If this option is set to No -(the default) then if a vetoed directory contains any non-vetoed files or -directories then the directory delete will fail. This is usually what you -want. <P> -If this option is set to Yes, then Samba will attempt to recursively delete -any files and directories within the vetoed directory. This can be useful -for integration with file serving systems such as Netatalk, which create -meta-files within directories you might normally veto DOS/Windows users -from seeing (eg. .AppleDouble) <P> -Setting 'delete veto files = Yes' allows these directories to be -transparently deleted when the parent directory is deleted (so long as the -user has permissions to do so). <P> -<B>Default:</B> delete veto files = No <P> -<B>Example:</B> delete veto files = Yes <P> -See <A HREF="#veto files">veto files</A> <P> - -<H3><A NAME="dfree command">dfree command (G)</A></H3> -The dfree command setting should only be used on systems where a problem -occurs with the internal disk space calculations.

Under POSIX semantics, only the owner of the file or root -may change the timestamp. By default, Samba runs with POSIX semantics and -refuses to change the timestamp on a file if the user smbd is acting on -behalf of is not the file owner. Setting this option to Yes allows DOS -semantics and smbd will change the file timstamp as DOS requires. This is a -correct implementation of a previous compile-time options (UTIME_WORKAROUND) -which was broken and is now removed. <P> -<B>Default:</B> dos filetimes = No <P> -<B>Example:</B> dos filetimes = Yes <P> - -<H3><A NAME="dos filetime resolution">dos filetime resolution (S)</A></H3> -Under the DOS and Windows FAT filesystem, the finest granulatity on time -resolution is two seconds. Setting this parameter for a share causes Samba -to round the reported time down to the nearest two second boundary when a -query call that requires one second resolution is made to smbd. <P> -This option is mainly used as a compatibility option for Visual C++ when -used against Samba shares. If oplocks are enabled on a share, Visual C++ -uses two different time reading calls to check if a file has changed since -it was last read. One of these calls uses a one-second granularity, the -other uses a two second granularity. As the two second call rounds any odd -second down, then if the file has a timestamp of an odd number of seconds -then the two timestamps will not match and Visual C++ will keep reporting -the file has changed. Setting this option causes the two timestamps to -match, and Visual C++ is happy. <P> -<B>Default:</B> dos filetime resolution = No <P> -<B>Example:</B> dos filetime resolution = Yes <P> - -<H3><A NAME="encrypt passwords">encrypt passwords (G)</A></H3> -This boolean controls whether encrypted passwords will be negotiated with -the client. Note that Windows NT 4.0 SP3 and above will by default expect -encrypted passwords unless a registry entry is changed.

It takes the usual substitutions. <P> -An interesting example is to send the users a welcome message every time -they log in. Maybe a message of the day? Here is an example: <P> -exec = csh -c 'echo \"Welcome to %S!\" | \ /usr/local/samba/bin/smbclient -M %m -I %I' & <P> -Of course, this could get annoying after a while :-) <P> -See also <A HREF="#postexec">postexec</A> <P> -<B>Default:</B> none (no command executed) <P> -<B>Example:</B> exec = echo \"%u connected to %S from %m (%I)\" >> /tmp/log <P> - - -<H3><A NAME="fake directory create times">fake directory create times (S)</A></H3> -NTFS and Windows VFAT file systems keep a create time for all files and -directories. This is not the same as the ctime - status change time - that -Unix keeps, so Samba by default reports the earliest of the various times -Unix does keep. Setting this parameter for a share causes Samba to always -report midnight 1-1-1980 as the create time for directories. <P> -This option is mainly used as a compatibility option for Visual C++ -when used against Samba shares. Visual C++ generated makefiles have the -object directory as a dependency for each object file, and a make rule -to create the directory. Also, when NMAKE compares timestamps it uses the -creation time when examining a directory. Thus the object directory will -be created if it does not exist, but once it does exist it will always -have an earlier timestamp than the object files it contains. <P> -However, Unix time semantics mean that the create time reported by Samba -will be updated whenever a file is created or deleted in the directory. -NMAKE therefore finds all object files in the object directory bar the last -one built are out of date compared to the directory and rebuilds them. -Enabling this option ensures directories always predate their contents and -an NMAKE build will proceed as expected. <P> -<B>Default:</B> fake directory create times = No <P> -<B>Example:</B> fake directory create times = Yes <P> - -<H3><A NAME="fake oplocks">fake oplocks (S)</A></H3> -Oplocks are the way that SMB clients get permission from a server to locally -cache file operations. If a server grants an oplock (opportunistic -lock) then the client is free to assume that it is the only one accessing -the file and it will aggressively cache file data. With some oplock types -the client may even cache file open/close operations. This can give enormous -performance benefits. <P> -When you set "fake oplocks = yes" Samba will always grant oplock requests -no matter how many clients are using the file. <P> -By enabling this option on all read-only shares or shares that you know -will only be accessed from one client at a time you will see a big performance -improvement on many operations. If you enable this option on shares where -multiple clients may be accessing the files read-write at the same time -you can get data corruption. Use this option carefully! <P> -It is generally much better to use the real oplock support except for -physically read-only media such as CDROMs. <P> -<B>Default:</B> fake oplocks = No <P> -<B>Example:</B> fake oplocks = Yes <P> - -<H3><A NAME="follow symlinks">follow symlinks (S)</A></H3> -This parameter allows the Samba administrator to stop smbd from following -symbolic links in a particular share. Setting this parameter to "No" prevents -any file or directory that is a symbolic link from being followed (the -user will get an error). This option is very useful to stop users from -adding a symbolic link to /etc/pasword in their home directory for instance. -However it will slow filename lookups down slightly. <P> -<B>Default:</B> follow symlinks = Yes (smbd will follow symbolic links)<P> - -<H3><A NAME="force create mode">force create mode (S)</A></H3> -This parameter specifies a set of UNIX mode bit permissions that will *always* -be set on a file created by Samba. This is done by bitwise 'OR'ing these -bits onto the mode bits of a file that is being created.

For unix systems that use -an automounter, the user's home directory will often be mounted on a -workstation on demand from a remote server. When the Samba logon server is -not the actual home directory server, two network hops are required to access -the home directory and this can be very slow especially with writing via -Samba to an NFS mounted directory. This option allows samba to return the -home share as being on a different server to the logon server and as long as -a samba daemon is running on the home directory server, it will be mounted -on the Samba client directly from the directory server.

By default this -option is disabled so a client can supply a username to be used by the -server. <P> -Note that this also means Samba won't try to deduce usernames from the -service name. This can be annoying for the [homes] section. To get around -this you could use "<A HREF="#username">username</A> = %S" which means your -"username" list will be just the service name, which for home directories -is the name of the user. <P> -<B>Default: </B> only user = No <P> -<B>Example: </B> only user = Yes <P> - -<H3><A NAME="oplocks">oplocks (S)</A></H3> -This boolean option tells smbd whether to issue oplocks (opportunistic locks) -to file open requests on this share.

In this mode the strings passed to and received from the -passwd chat are printed in the smbd log with a debug level of 100. This -is a dangerous option as it will allow plaintext passwords to be seen -in the smbd log. It is available to help Samba admins debug their passwd -chat scripts and should be turned off after this has been done.

Any occurrences of %u will be replaced with the user name. <P> -Also note that many passwd programs insist in "reasonable" -passwords, such as a minimum length, or the inclusion of mixed case chars -and digits. This can pose a problem as some clients (such as Windows for -Workgroups) uppercase the password before sending it. <P> -<B>Default:</B> passwd program = /bin/passwd <P> -<B>Example:</B> passwd program = /sbin/passwd %u <P> - -<H3><A NAME="password level">password level (G)</A></H3> -Some client/server combinations have difficulty with mixed-case -passwords. One offending client is Windows for Workgroups, which for some -reason forces passwords to upper case when using the LANMAN1 protocol, -but leaves them alone when using COREPLUS! <P> -This parameter defines the maximum number of characters that may be upper -case in passwords. <P> -For example, say the password given was "FRED". If password level is set to -1 (one), the following combinations would be tried if "FRED" failed: "Fred", -"fred", "fRed", "frEd", "freD". If password level was set to 2 (two), the -following combinations would also be tried: "FRed", "FrEd", "FreD", "fREd", -"fReD", "frED". And so on. <P> -The higher value this parameter is set to the more likely it is that a mixed -case password will be matched against a single case password. However, you -should be aware that use of this parameter reduces security and increases the -time taken to process a new connection. <P> -A value of zero will cause only two attempts to be made - the password -as is and the password in all-lower case. <P> -If you find the connections are taking too long with this option then you -probably have a slow crypt() routine. Samba now comes with a fast "ufc crypt" -that you can select in the Makefile. You should also make sure the -PASSWORD_LENGTH option is correct for your system in local.h and includes.h. -On most systems only the first 8 chars of a password are significant so -PASSWORD_LENGTH should be 8, but on some longer passwords are significant. -The includes.h file tries to select the right length for your system. <P> -<B>Default:</B> password level = 0 <P> -<B>Example:</B> password level = 4 <P> - -<H3><A NAME="password server">password server (G)</A></H3> -By specifying the name of another SMB server (such as a WinNT box) with this -option, and using "<A HREF="#security">security</A> = server" you can get -Samba to do all its username/password validation via a remote server. <P> -This options sets the name of the password server to use. It must be a netbios -name, so if the machine's netbios name is different from its internet name -then you may have to add its netbios name to /etc/hosts. <P> -Note that with Samba 1.9.18p4 and above the name of the password server is -looked up using the <A HREF="#name resolve order">name resolve order</A> -parameter and so may resolved by any method and order described in that -parameter. <P> -The password server much be a machine capable of using the "LM1.2X002" -or the "LM NT 0.12" protocol, and it must be in user level security mode. <P> -NOTE: Using a password server means your UNIX box (running Samba) is -only as secure as your password server. DO NOT CHOOSE A PASSWORD SERVER -THAT YOU DON'T COMPLETELY TRUST. <P> -Never point a Samba server at itself for password serving. This will cause a -loop and could lock up your Samba server! <P> -The name of the password server takes the standard substitutions, but -probably the only useful one is %m, which means the Samba server will -use the incoming client as the password server. If you use this then you -better trust your clients, and you better restrict them with -<A HREF="#hosts allow">hosts allow</A>! <P> -If you list several hosts in the "password server" option then smbd will -try each in turn till it finds one that responds. This is useful in case -your primary server goes down. <P> -If you are using a WindowsNT server as your password server then you will -have to ensure that your users are able to login from the Samba server, as -the network logon will appear to come from there rather than from the users -workstation. <P> - -<H3><A NAME="path">path (S)</A></H3> -A synonym for this parameter is "directory". <P> -This parameter specifies a directory to which the user of the service is to -be given access.

Typically the command -specified will submit the spool file to the host's printing subsystem, but -there is no requirement that this be the case. The server will not remove -the spool file, so whatever command you specify should remove the spool file -when it has been processed, otherwise you will need to manually remove old -spool files. <P> -The print command is simply a text string. It will be used verbatim, with -two exceptions: All occurrences of "%s" will be replaced by the appropriate -spool file name, and all occurrences of "%p" will be replaced by the -appropriate printer name. The spool file name is generated automatically by -the server, the <A HREF="#printer name">printer name</A> is discussed below. <P> -The full path name will be used for the filename if %s is not preceded by a -/. If you don't like this (it can stuff up some lpq output) then use %f -instead. Any occurrences of %f get replaced by the spool filename without -the full path at the front. <P> -The print command MUST contain at least one occurrence of "%s" or %f - -the "%p" is optional. At the time a job is submitted, if no printer name is -supplied the "%p" will be silently removed from the printer command. <P> -If specified in the [global] section, the print command given will be used for -any printable service that does not have its own print command specified.<P> -If there is neither a specified print command for a printable service nor a -global print command, spool files will be created but not processed and (most -importantly) not removed. <P> -Note that printing may fail on some UNIXes from the "nobody" account. If this -happens then create an alternative guest account that can print and set the -<A HREF="#guest account">guest account</A> in the [global] section. <P> -You can form quite complex print commands by realising that they are -just passed to a shell.

If the amount of data being transferred in several of the SMB -commands (currently SMBwrite, SMBwriteX and SMBreadbraw) is larger than this -value then the server begins writing the data before it has received the -whole packet from the network, or in the case of SMBreadbraw, it begins -writing to the network before all the data has been read from disk. <P> -This overlapping works best when the speeds of disk and network access are -similar, having very little effect when the speed of one is much greater -than the other. <P> -The default value is 2048, but very little experimentation has been done -yet to determine the optimal value, and it is likely that the best value -will vary greatly between systems anyway. A value over 65536 is pointless -and will cause you to allocate memory unnecessarily. <P> -<B>Default:</B> read size = 2048 <P> -<B>Example:</B> read size = 8192 <P> - -<H3><A NAME="remote announce">remote announce (G)</A></H3> -This option allows you to setup nmbd to periodically announce itself to -arbitrary IP addresses with an arbitrary workgroup name. <P> -This is useful if you want your Samba server to appear in a remote workgroup -for which the normal browse propagation rules don't work. The remote -workgroup can be anywhere that you can send IP packets to. <P> -For example: <P> -remote announce = 192.168.2.255/SERVERS 192.168.4.255/STAFF <P> -the above line would cause nmbd to announce itself to the two given IP -addresses using the given workgroup names. If you leave out the workgroup -name then the one given in the <A HREF="#workgroup">workgroup</A> option is -used instead. <P> -The IP addresses you choose would normally be the broadcast -addresses of the remote networks, but can also be the IP addresses of -known browse masters if your network config is that stable. <P> -This option replaces similar functionality from the nmbd lmhosts file. <P> - -<H3><A NAME="remote browse sync">remote browse sync (G)</A></H3> -This option allows you to setup nmbd to periodically request -synchronisation of browse lists with the master browser of a samba server -that is on a remote segment. This option will allow you to gain browse -lists for multiple workgroups across routed networks. This is done in a -manner that does not work with any non-samba servers. <P> -This is useful if you want your Samba server and all local clients to appear -in a remote workgroup for which the normal browse propagation rules don't -work. The remote workgroup can be anywhere that you can send IP packets to.<P> -For example: <P> -remote browse sync = 192.168.2.255 192.168.4.255 <P> -the above line would cause nmbd to request the master browser on the -specified subnets or addresses to synchronise their browse lists with the -local server. <P> -The IP addresses you choose would normally be the broadcast addresses -of the remote networks, but can also be the IP addresses of known browse -masters if your network config is that stable. If a machine IP address -is given Samba makes NO attempt to validate that the remote machine is -available, is listening, nor that it is in fact the browse master on it's -segment. <P> - -<H3><A NAME="revalidate">revalidate (S)</A></H3> -This options controls whether Samba will allow a previously validated -username/password pair to be used to attach to a share. Thus if you connect -to \\server\share1 then to \\server\share2 it won't automatically allow the -client to request connection to the second share as the same username as the -first without a password. <P> -If "revalidate" is Yes then the client will be denied automatic access as -the same username. <P> -<B>Default:</B> revalidate = No <P> -<B>Example:</B> revalidate = Yes <P> - -<H3><A NAME="root directory">root directory (G)</A></H3> -Synonyms for this parameter are 'root dir' and 'root'. <P> -The server will chroot() to this directory on startup. This is not strictly -necessary for secure operation. Even without it the server will deny access -to files not in one of the service entries. It may also check for, and deny -access to, soft links to other parts of the filesystem, or attempts to use -.. in file names to access other directories (depending on the setting of -the <A HREF="#wide links">wide links</A> parameter). <P> -Adding a "root dir" entry other than "/" adds an extra level -of security, but at a price. It absolutely ensures that no access is given -to files not in the sub-tree specified in the "root dir" option, *including* -some files needed for complete operation of the server. To maintain full -operability of the server you will need to mirror some system files into -the "root dir" tree. In particular you will need to mirror /etc/passwd -(or a subset of it), and any binaries or configuration files needed for -printing (if required). The set of files that must be mirrored is operating -system dependent. <P> -<B>Default:</B> root directory = / <P> -<B>Example:</B> root directory = /homes/smb <P> - -<H3><A NAME="root postexec">root postexec (S)</A></H3> -This is the same as <A HREF="#postexec">postexec</A> except that -the command is run as root.

This is useful for mounting filesystems (such as CDROMS) before a -connection is finalised. <P> - -<H3><A NAME="security">security (G)</A></H3> -This option affects how clients respond to Samba. <P> -The option sets the "security mode bit" in replies to protocol negotiations -to turn share level security on or off. Clients decide based on this bit -whether (and how) to transfer user and password information to the server.<P> -The default is "security=SHARE", mainly because that was the only option at -one stage. <P> -The alternatives are "security = user" or "security = server". <P> -If your PCs use usernames that are the same as their usernames on the -UNIX machine then you will want to use "security = user". If you mostly -use usernames that don't exist on the UNIX box then use "security = share".<P> -There is a bug in WfWg that may affect your decision. When in user level -security a WfWg client will totally ignore the password you type in the -"connect drive" dialog box. This makes it very difficult (if not impossible) -to connect to a Samba service as anyone except the user that you are logged -into WfWg as. <P> -If you use "security = server" then Samba will try to validate -the username/password by passing it to another SMB server, such as an -NT box. If this fails it will revert to "security = USER". <P> -See the <A HREF="#password server">password server</A> option for more -details. <P> -<B>Default:</B> security = SHARE <P> -<B>Example:</B> security = USER <P> - -<H3><A NAME="server string">server string (G)</A></H3> -This controls what string will show up in the printer comment box in print -manager and next to the IPC connection in "net view". It can be any string -that you wish to show to your users. <P> -It also sets what will appear in browse lists next to the machine name. <P> -A %v will be replaced with the Samba version number. <P> -A %h will be replaced with the hostname. <P> -<B>Default:</B> server string = Samba %v <P> -<B>Example:</B> server string = University of GNUs Samba Server <P> - -<H3><A NAME="set directory">set directory (S)</A></H3> -If 'set directory = No', then users of the service may not use the setdir -command to change directory. <P> -The setdir command is only implemented in the Digital Pathworks -client. See the Pathworks documentation for details. <P> -<B>Default:</B> set directory = No <P> -<B>Example:</B> set directory = Yes <P> - -<H3><A NAME="shared mem size">shared mem size (G)</A></H3> -This parameter is only useful when Samba has been compiled with -FAST_SHARE_MODES. It specifies the size of the shared -memory (in bytes) to use between smbd processes. You should never change -this parameter unless you have studied the source and know what you are -doing. This parameter defaults to 1024 multiplied by the setting of the -maximum number of open files in the file local.h in the Samba source code. -MAX_OPEN_FILES is normally set to 100, so this parameter defaults to 102400 -bytes. <P> -<B>Default</B> shared mem size = 102400 <P> - -<H3><A NAME="smb passwd file">smb passwd file (G)</A></H3> -This option sets the path to the encrypted smbpasswd file. This is a -*VERY DANGEROUS OPTION* if the smb.conf is user writable. By default the -path to the smbpasswd file is compiled into Samba. <P> - -<H3><A NAME="smbrun">smbrun (G)</A></H3> -This sets the full path to the smbrun binary. This defaults to the value in -the Makefile. <P> -You must get this path right for many services to work correctly. <P> -<B>Default:</B> taken from Makefile <P> -<B>Example:</B> smbrun = /usr/local/samba/bin/smbrun <P> - -<H3><A NAME="share modes">share modes (S)</A></H3> -This enables or disables the honouring of the "share modes" during a file -open. These modes are used by clients to gain exclusive read or write access -to a file. <P> -These open modes are not directly supported by UNIX, so they are simulated -using lock files in the <A HREF="#lock dir">lock dir</A>. The "lock dir" -specified in smb.conf must be readable by all users. <P> -The share modes that are enabled by this option are DENY_DOS, DENY_ALL, -DENY_READ, DENY_WRITE, DENY_NONE and DENY_FCB. <P> -Enabling this option gives full share compatibility but may cost a bit of -processing time on the UNIX server. They are enabled by default. <P> -<B>Default:</B> share modes = Yes <P> -<B>Example:</B> share modes = No <P> - -<H3><A NAME="short preserve case">short preserve case (S)</A></H3> -This controls if new short filenames are created with the case that the client -passes, or if they are forced to be the "default" case. <P> -<B>Default:</B> short preserve case = No <P> -See the section on <A HREF="#NAME MANGLING">NAME MANGLING</A> for a fuller -discussion. <P> - -<H3><A NAME="socket address">socket address (G)</A></H3> -This option allows you to control what address Samba will listen for -connections on. This is used to support multiple virtual interfaces on the -one server, each with a different configuration. <P> -By default samba will accept connections on any address. <P> -<B>Example:</B> socket address = 192.168.2.20 <P> - -<H3><A NAME="socket options">socket options (G)</A></H3> -This option (which can also be invoked with the -O command line option) allows -you to set socket options to be used when talking with the client. <P> -Socket options are controls on the networking layer of the operating systems -which allow the connection to be tuned. <P> -This option will typically be used to tune your Samba server for optimal -performance for your local network. There is no way that Samba can know what -the optimal parameters are for your net, so you must experiment and choose -them yourself. I strongly suggest you read the appropriate documentation for -your operating system first (perhaps "man setsockopt" will help). <P> -You may find that on some systems Samba will say "Unknown socket option" when -you supply an option. This means you either mis-typed it or you need to add -an include file to includes.h for your OS. If the latter is the case please -send the patch to me (samba-bugs@samba.anu.edu.au). <P> -Any of the supported socket options may be combined in any way you like, as -long as your OS allows it. <P> -This is the list of socket options currently settable using this option: <P> -SO_KEEPALIVE <BR> -SO_REUSEADDR <BR> -SO_BROADCAST <BR> -TCP_NODELAY <BR> -IPTOS_LOWDELAY <BR> -IPTOS_THROUGHPUT <BR> -SO_SNDBUF * <BR> -SO_RCVBUF * <BR> -SO_SNDLOWAT * <BR> -SO_RCVLOWAT * <P> -Those marked with a * take an integer argument. The others can optionally take -a 1 or 0 argument to enable or disable the option, by default they will -be enabled if you don't specify 1 or 0. <P> -To specify an argument use the syntax SOME_OPTION=VALUE for example -SO_SNDBUF=8192. Note that you must not have any spaces before or after the = -sign. <P> -If you are on a local network then a sensible option might be <P> -socket options = IPTOS_LOWDELAY <P> -If you have an almost unloaded local network and you don't mind a lot -of extra CPU usage in the server then you could try <P> -socket options = IPTOS_LOWDELAY TCP_NODELAY <P> -If you are on a wide area network then perhaps try setting IPTOS_THROUGHPUT. <P> -Note that several of the options may cause your Samba server to fail -completely. Use these options with caution! <P> -<B>Default:</B> no socket options <P> -<B>Example:</B> socket options = IPTOS_LOWDELAY <P> - -<H3><A NAME="status">status (G)</A></H3> -This enables or disables logging of connections to a status -file that <B>smbstatus</B> can read. <P> -With this disabled <B>smbstatus</B> won't be able to tell you what connections -are active. <P> -<B>Default:</B> status = Yes <P> -<B>Example:</B> status = No <P> - -<H3><A NAME="strict locking">strict locking (S)</A></H3> -This is a boolean that controls the handling of file locking in the server. -When this is set to yes the server will check every read and write access -for file locks, and deny access if locks exist. This can be slow on some -systems. <P> -When strict locking is "no" the server does file lock checks only when the -client explicitly asks for them. <P> -Well behaved clients always ask for lock checks when it is important, -so in the vast majority of cases "strict locking = no" is preferable. <P> -<B>Default:</B> strict locking = No <P> -<B>Example:</B> strict locking = Yes <P> - -<H3><A NAME="strip dot">strip dot (G)</A></H3> -This is a boolean that controls whether to strip trailing dots off -UNIX filenames. This helps with some CDROMs that have filenames ending -in a single dot. <P> -<B>Default:</B> strip dot = No <P> -<B>Example:</B> strip dot = Yes <P> - -<H3><A NAME="syslog">syslog (G)</A></H3> -This parameter maps how Samba debug messages are logged onto -the system syslog logging levels. Samba debug level zero maps onto syslog -LOG_ERR, debug level one maps onto LOG_WARNING, debug level two maps to -LOG_NOTICE, debug level three maps onto LOG_INFO. The paramter sets the -threshold for doing the mapping, all Samba debug messages above this threashold -are mapped to syslog LOG_DEBUG messages. <P> -<B>Default:</B> syslog = 1 <P> - -<H3><A NAME="syslog only">syslog only (G)</A></H3> -If this parameter is set then Samba debug messages are logged -into the system syslog only, and not to the debug log files. <P> -<B>Default:</B> syslog only = no <P> - -<H3><A NAME="sync always">sync always (S)</A></H3> -This is a boolean parameter that controls whether writes will always be -written to stable storage before the write call returns. If this is No then -the server will be guided by the client's request in each write call (clients -can set a bit indicating that a particular write should be synchronous). If -this is Yes then every write will be followed by a fsync() call to ensure the -data is written to disk. <P> -<B>Default:</B> sync always = No <P> -<B>Example:</B> sync always = Yes <P> - -<H3><A NAME="time offset">time offset (G)</A></H3> -This parameter is a setting in minutes to add to the normal GMT to local time -conversion.

If this is set to Yes the -<A HREF="#passwd program">passwd program</A> -program is called *AS ROOT* - to allow the new UNIX password to be set -without access to the old UNIX password (as the SMB password has change -code has no access to the old password cleartext, only the new).

This is useful for setting up mail -clients and WWW browsers on systems used by more than one person. <P> -<B>Default:</B> unix realname = No <P> -<B>Example:</B> unix realname = Yes <P> - -<H3><A NAME="update encrypted">update encrypted (S)</A></H3> -This boolean parameter allows a user logging on with a plaintext password to -have their encrypted (hashed) password in the smbpasswd file to be updated -automatically as they log on. This option allows a site to migrate from -plaintext password authentication (users authenticate with plaintext -password over the wire, and are checked against a UNIX account database) to -encrypted password authentication (the SMB challenge/response authentication -mechanism) without forcing all users to re-enter their passwords via smbpasswd -at the time the change is made. This is a convenience option to allow the -change over to encrypted passwords to be made over a longer period. Once all -users have encrypted representations of their passwords in the smbpasswd file \ -this parameter should be set to "No". <P> -In order for this parameter to work correctly the -i<A HREF="#encrypt passwords">encrypt passwords</A> must be set to "No" when -this parameter is set to "Yes". <P> -Note that even when this parameter is set a user authenticating to smbd must -still enter a valid password in order to connect correctly, and to update their -hashed (smbpasswd) passwords. <P> -<B>Default:</B> update encrypted = No <P> - -<H3><A NAME="use rhosts">use rhosts (S)</A></H3> -<B>Default:</B> use rhosts = No <P> - -<H3><A NAME="username">username (S)</A></H3> -A synonym for this parameter is 'user'. <P> -Multiple users may be specified in a comma-delimited list, in which case the -supplied password will be tested against each username in turn (left to -right). <P> -The username= line is needed only when the PC is unable to supply its own -username. This is the case for the coreplus protocol or where your users have -different WfWg usernames to UNIX usernames. In both these cases you may also -be better using the \\server\share%user syntax instead. <P> -The username= line is not a great solution in many cases as it means Samba -will try to validate the supplied password against each of the usernames in -the username= line in turn. This is slow and a bad idea for lots of users in -case of duplicate passwords. You may get timeouts or security breaches using -this parameter unwisely. <P> -Samba relies on the underlying UNIX security. This parameter does not restrict -who can login, it just offers hints to the Samba server as to what usernames -might correspond to the supplied password. Users can login as whoever they -please and they will be able to do no more damage than if they started a -telnet session. The daemon runs as the user that they log in as, so they -cannot do anything that user cannot do. <P> -To restrict a service to a particular set of users you can use the -<A HREF="#valid users">valid users</A> line. <P> -If any of the usernames begin with a @ then the name will be looked -up in the groups file and will expand to a list of all users in the group -of that name. Note that searching though a groups file can take quite some -time, and some clients may time out during the search. <P> -See the section below on -<A HREF="#USERNAME/PASSWORD VALIDATION">USERNAME/PASSWORD VALIDATION</A> -for more information on how this parameter determines access to the services.<P> -<B>Default:</B> The guest account if a guest service, else the name of the service. <P> -<B>Examples:</B>username = fredusername = fred, mary, jack, jane, @users, @pcgroup <P> - -<H3><A NAME="username level">username level (G)</A></H3> -This option helps Samba to try and 'guess' at the real UNIX username, -as many DOS clients send an all-uppercase username. By default Samba tries -all lowercase, followed by the username with the first letter capitalized, -and fails if the username is not found on the UNIX machine. <P> -If this parameter is set to non-zero the behaviour changes. This parameter -is a number that specifies the number of uppercase combinations to try whilst -trying to determine the UNIX user name. The higher the number the more -combinations will be tried, but the slower the discovery of usernames will be. -Use this parameter when you have strange usernames on your UNIX machine, -such as 'AstrangeUser'. <P> -<B>Default:</B> username level = 0 <P> -<B>Example:</B> username level = 5 <P> - -<H3><A NAME="username map">username map (G)</A></H3> -This option allows you to to specify a file containing -a mapping of usernames from the clients to the server. This can be used -for several purposes. The most common is to map usernames that users use -on DOS or Windows machines to those that the UNIX box uses. The other is -to map multiple users to a single username so that they can more easily -share files. <P> -The map file is parsed line by line. Each line should contain -a single UNIX username on the left then a '=' followed by a list of usernames -on the right. The list of usernames on the right may contain names of the -form @group in which case they will match any UNIX username in that group. -The special client name '*' is a wildcard and matches any name. <P> -The file is processed on each line by taking the supplied username and -comparing it with each username on the right hand side of the '=' signs. If -the supplied name matches any of the names on the right hand side then it is -replaced with the name on the left. Processing then continues with the next -line. <P> -If any line begins with a '#' or a ';' then it is ignored <P> -If any line begins with an ! then the processing will stop after that line if -a mapping was done by the line. Otherwise mapping continues with every line -being processed. Using ! is most useful when you have a wildcard mapping line -later in the file. <P> -For example to map from the name "admin" or "administrator" to the UNIX name -"root" you would use <P> -root = admin administrator <P> -Or to map anyone in the UNIX group "system" to the UNIX name "sys" you would -use <P> -sys = @system <P> -You can have as many mappings as you like in a username map file. <P> -You can map Windows usernames that have spaces in them by using -double quotes around the name.
