This file format -has been evolving with Samba and has had several different formats in the -past. -File Format -The format of the smbpasswd file used by Samba 2.0 is very -similar to the familiar Unix passwd (5) file. It is an ASCII file containing -one line for each user. Each field within each line is separated from the -next by a colon. Any entry beginning with # is ignored. The smbpasswd file -contains the following information for each user: -name - -This is the user name. It must be a name that already exists in the standard -UNIX passwd file. uid - -This is the UNIX uid. It must match the uid field for the same user entry -in the standard UNIX passwd file. If this does not match then Samba will -refuse to recognize this smbpasswd file entry as being valid for a user. -Lanman Password Hash - -This is the LANMAN hash of the users password, encoded as 32 hex digits. -The LANMAN hash is created by DES encrypting a well known string with the -users password as the DES key. This is the same password used by Windows -95/98 machines. Note that this password hash is regarded as weak as it is -vulnerable to dictionary attacks and if two users choose the same password -this entry will be identical (i.e. the password is not "salted" as the UNIX -password is). If the user has a null password this field will contain the -characters CW"NO PASSWORD" as the start of the hex string. If the hex string -is equal to 32 CW'X' characters then the users account is marked as disabled -and the user will not be able to log onto the Samba server. WARNING !!. Note -that, due to the challenge-response nature of the SMB/CIFS authentication -protocol, anyone with a knowledge of this password hash will be able to -impersonate the user on the network. For this reason these hashes are known -as "plain text equivalent" and must NOT be made available to anyone but -the root user. To protect these passwords the smbpasswd file is placed in -a directory with read and traverse access only to the root user and the -smbpasswd file itself must be set to be read/write only by root, with no -other access. NT Password Hash - -This is the Windows NT hash of the users password, encoded as 32 hex digits. -The Windows NT hash is created by taking the users password as represented -in 16-bit, little-endian UNICODE and then applying the MD4 (internet rfc1321) -hashing algorithm to it. This password hash is considered more secure than -the Lanman Password Hash as it preserves the case of the password and uses -a much higher quality hashing algorithm. However, it is still the case that -if two users choose the same password this entry will be identical (i.e. -the password is not "salted" as the UNIX password is). WARNING !!. Note that, -due to the challenge-response nature of the SMB/CIFS authentication protocol, -anyone with a knowledge of this password hash will be able to impersonate -the user on the network. For this reason these hashes are known as "plain -text equivalent" and must NOT be made available to anyone but the root -user. To protect these passwords the smbpasswd file is placed in a directory -with read and traverse access only to the root user and the smbpasswd file -itself must be set to be read/write only by root, with no other access. -Account Flags - -This section contains flags that describe the attributes of the users account. -In the Samba2.0 release this field is bracketed by CW'[' and CW']' characters -and is always 13 characters in length (including the CW'[' and CW']' characters). -The contents of this field may be any of the characters. o'U' This means this -is a "User" account, i.e. an ordinary user. Only User and Workstation Trust -accounts are currently supported in the smbpasswd file. o'N' This means the -account has no password (the passwords in the fields Lanman Password Hash -and NT Password Hash are ignored). Note that this will only allow users -to log on with no password if the null passwords parameter is set in the -smb.conf (5) config file. o'D' This means the account is disabled and no SMB/CIFS -logins will be allowed for this user. o'W' This means this account is a "Workstation -Trust" account. This kind of account is used in the Samba PDC code stream -to allow Windows NT Workstations and Servers to join a Domain hosted by -a Samba PDC. Other flags may be added as the code is extended in future. -The rest of this field space is filled in with spaces. Last Change Time - -This field consists of the time the account was last modified. It consists -of the characters CWLCT- (standing for "Last Change Time") followed by a -numeric encoding of the UNIX time in seconds since the epoch (1970) that -the last change was made. Following fields - -All other colon separated fields are ignored at this time. -Notes -In previous -versions of Samba (notably the 1.9.18 series) this file did not contain the -Account Flags or Last Change Time fields. The Samba 2.0 code will read and -write these older password files but will not be able to modify the old -entries to add the new fields. New entries added with smbpasswd (8) will -contain the new fields in the added accounts however. Thus an older smbpasswd -file used with Samba 2.0 may end up with some accounts containing the new -fields and some not. -In order to convert from an old-style smbpasswd file -to a new style, run the script convert_smbpasswd, installed in the Samba -CWbin/ directory (the same place that the smbd and nmbd binaries are installed) -as follows: - - - - - - cat old_smbpasswd_file | convert_smbpasswd > new_smbpasswd_file - - - - - -The convert_smbpasswd script reads from stdin and writes to stdout so -as not to overwrite any files by accident. -Once this script has been run, -check the contents of the new smbpasswd file to ensure that it has not -been damaged by the conversion script (which uses awk), and then replace -the CW<old smbpasswd file> with the CW<new smbpasswd file>. -Version -This man -page is correct for version 2.0 of the Samba suite. -See Also -smbpasswd (8), -samba (7), and the Internet RFC1321 for details on the MD4 algorithm. -Author -The -original Samba software and related utilities were created by Andrew Tridgell -samba@samba.org.

On a UNIX machine the encrypted SMB passwords -are usually stored in the smbpasswd (5) file. -When run by an ordinary user -with no options. smbpasswd will prompt them for their old smb password and -then ask them for their new password twice, to ensure that the new password -was typed correctly. No passwords will be echoed on the screen whilst being -typed.

This option -is ignored if the username following already exists in the smbpasswd file -and it is treated like a regular change password command. Note that the -user to be added must already exist in the system password file (usually -/etc/passwd) else the request to add the user will fail. This option is -only available when running smbpasswd as root. -xThis option specifies that -the username following should be deleted from the local smbpasswd file. -This option is only available when running smbpasswd as root. -dThis option -specifies that the username following should be disabled in the local smbpasswd -file. This is done by writing a 'D' flag into the account control space in -the smbpasswd file. Once this is done all attempts to authenticate via SMB -using this username will fail. If the smbpasswd file is in the 'old' format -(pre-Samba 2.0 format) there is no space in the users password entry to write -this information and so the user is disabled by writing 'X' characters into -the password space in the smbpasswd file. See smbpasswd (5) for details -on the 'old' and new password file formats. This option is only available -when running smbpasswd as root. -eThis option specifies that the username -following should be enabled in the local smbpasswd file, if the account -was previously disabled. If the account was not disabled this option has -no effect. Once the account is enabled then the user will be able to authenticate -via SMB once again. If the smbpasswd file is in the 'old' format then smbpasswd -will prompt for a new password for this user, otherwise the account will -be enabled by removing the 'D' flag from account control space in the smbpasswd -file. See smbpasswd (5) for details on the 'old' and new password file formats. -This option is only available when running smbpasswd as root. -D debugleveldebuglevel -is an integer from 0 to 10. The default value if this parameter is not -specified is zero. The higher this value, the more detail will be logged -to the log files about the activities of smbpasswd. At level 0, only critical -errors and serious warnings will be logged. Levels above 1 will generate -considerable amounts of log data, and should only be used when investigating -a problem. Levels above 3 are designed for use only by developers and generate -HUGE amounts of log data, most of which is extremely cryptic. -nThis option -specifies that the username following should have their password set to -null (i.e. a blank password) in the local smbpasswd file. This is done by -writing the string "NO PASSWORD" as the first part of the first password -stored in the smbpasswd file. Note that to allow users to logon to a Samba -server once the password has been set to "NO PASSWORD" in the smbpasswd -file the administrator must set the following parameter in the [global] -section of the smb.conf file : null passwords = true This option is only -available when running smbpasswd as root. -r remote machine nameThis option -allows a user to specify what machine they wish to change their password -on. Without this parameter smbpasswd defaults to the local host. The "remote -machine name" is the NetBIOS name of the SMB/CIFS server to contact to -attempt the password change. This name is resolved into an IP address using -the standard name resolution mechanism in all programs of the Samba suite. -See the -R name resolve order parameter for details on changing this resolving -mechanism. The username whose password is changed is that of the current -UNIX logged on user. See the -U username parameter for details on changing -the password for a different username. Note that if changing a Windows NT -Domain password the remote machine specified must be the Primary Domain -Controller for the domain (Backup Domain Controllers only have a read-only -copy of the user account database and will not allow the password change). -Note that Windows 95/98 do not have a real password database so it is not -possible to change passwords specifying a Win95/98 machine as remote machine -target. -R name resolve orderThis option allows the user of smbclient to -determine what name resolution services to use when looking up the NetBIOS -name of the host being connected to. The options are :"lmhosts", "host", -"wins" and "bcast". They cause names to be resolved as follows : olmhosts -: Lookup an IP address in the Samba lmhosts file. ohost : Do a standard -host name to IP address resolution, using the system /etc/hosts, NIS, or -DNS lookups. This method of name resolution is operating system dependent. -For instance on IRIX or Solaris, this may be controlled by the /etc/nsswitch.conf -file). owins : Query a name with the IP address listed in the wins server -parameter in the smb.conf file. If no WINS server has been specified this -method will be ignored. obcast : Do a broadcast on each of the known local -interfaces listed in the interfaces parameter in the smb.conf file. This -is the least reliable of the name resolution methods as it depends on the -target host being on a locally connected subnet. If this parameter is not -set then the name resolve order defined in the smb.conf file parameter -name resolve order will be used. The default order is lmhosts, host, wins, -bcast and without this parameter or any entry in the smb.conf file the -name resolution methods will be attempted in this order. -mThis option tells -smbpasswd that the account being changed is a MACHINE account. Currently -this is used when Samba is being used as an NT Primary Domain Controller. -PDC support is not a supported feature in Samba2.0 but will become supported -in a later release. If you wish to know more about using Samba as an NT -PDC then please subscribe to the mailing list samba-ntdom@samba.org. This -option is only available when running smbpasswd as root. -j DOMAINThis option -is used to add a Samba server into a Windows NT Domain, as a Domain member -capable of authenticating user accounts to any Domain Controller in the -same way as a Windows NT Server. See the security=domain option in the smb.conf -(5) man page. In order to be used in this way, the Administrator for the -Windows NT Domain must have used the program "Server Manager for Domains" -to add the primary NetBIOS name of the Samba server as a member of the -Domain. After this has been done, to join the Domain invoke smbpasswd with -this parameter. smbpasswd will then look up the Primary Domain Controller -for the Domain (found in the smb.conf file in the parameter password server -and change the machine account password used to create the secure Domain -communication. This password is then stored by smbpasswd in a file, read -only by root, called CW<Domain>.<Machine>.mac where CW<Domain> is the name of the -Domain we are joining and CW<Machine> is the primary NetBIOS name of the -machine we are running on. Once this operation has been performed the smb.conf -file may be updated to set the security=domain option and all future logins -to the Samba server will be authenticated to the Windows NT PDC. Note that -even though the authentication is being done to the PDC all users accessing -the Samba server must still have a valid UNIX account on that machine. This -option is only available when running smbpasswd as root. -U usernameThis -option may only be used in conjunction with the -r option. When changing -a password on a remote machine it allows the user to specify the user name -on that machine whose password will be changed. It is present to allow users -who have different user names on different systems to change these passwords. --hThis option prints the help string for smbpasswd, selecting the correct -one for running as root or as an ordinary user. -sThis option causes smbpasswd -to be silent (i.e. not issue prompts) and to read it's old and new passwords -from standard input, rather than from CW/dev/tty (like the passwd (1) -program does). This option is to aid people writing scripts to drive smbpasswd -usernameThis specifies the username for all of the root only options to -operate on. Only root can specify this parameter as only root has the permission -needed to modify attributes directly in the local smbpasswd file. NotesSince -smbpasswd works in client-server mode communicating with a local smbd for -a non-root user then the smbd daemon must be running for this to work. A -common problem is to add a restriction to the hosts that may access the -smbd running on the local machine by specifying a "allow hosts" or "deny -hosts" entry in the smb.conf file and neglecting to allow "localhost" access -to the smbd. In addition, the smbpasswd command is only useful if Samba -has been set up to use encrypted passwords. See the file ENCRYPTION.txt in -the docs directory for details on how to do this. VersionThis man page is -correct for version 2.0 of the Samba suite. AuthorThe original Samba software -and related utilities were created by Andrew Tridgell samba@samba.org.

When run as a normal -user it allows the user to change the password used for their SMB -sessions on any machines that store SMB passwords. -<p>By default (when run with no arguments) it will attempt to change the -current users SMB password on the local machine. This is similar to -the way the <strong>passwd (1)</strong> program works. <strong>smbpasswd</strong> differs from how -the <strong>passwd</strong> program works however in that it is not <em>setuid root</em> -but works in a client-server mode and communicates with a locally -running <a href="smbd.8.html"><strong>smbd</strong></a>. As a consequence in order for this -to succeed the <a href="smbd.8.html"><strong>smbd</strong></a> daemon must be running on -the local machine.

No passwords will be echoed on the screen whilst being -typed. If you have a blank smb password (specified by the string "NO -PASSWORD" in the <a href="smbpasswd.5.html"><strong>smbpasswd</strong></a> file) then just -press the <Enter> key when asked for your old password. -<p><strong>smbpasswd</strong> can also be used by a normal user to change their SMB -password on remote machines, such as Windows NT Primary Domain -Controllers.

When run as a normal user it allows the user to change +the password used for their SMB sessions on any machines that store +SMB passwords. +.PP +By default (when run with no arguments) it will attempt to +change the current users SMB password on the local machine. This is +similar to the way the \fBpasswd(1)\fR program works. +\fBsmbpasswd\fR differs from how the passwd program works +however in that it is not \fBsetuid root\fR but works in +a client-server mode and communicates with a locally running +\fBsmbd(8)\fR. As a consequence in order for this to +succeed the smbd daemon must be running on the local machine. On a +UNIX machine the encrypted SMB passwords are usually stored in +the \fIsmbpasswd(5)\fR file. +.PP +When run by an ordinary user with no options. smbpasswd +will prompt them for their old smb password and then ask them +for their new password twice, to ensure that the new password +was typed correctly. No passwords will be echoed on the screen +whilst being typed. If you have a blank smb password (specified by +the string "NO PASSWORD" in the smbpasswd file) then just press +the <Enter> key when asked for your old password. +.PP +smbpasswd can also be used by a normal user to change their +SMB password on remote machines, such as Windows NT Primary Domain +Controllers. See the (-r) and -U options below. +.PP +When run by root, smbpasswd allows new users to be added +and deleted in the smbpasswd file, as well as allows changes to +the attributes of the user in this file to be made. When run by root, +\fBsmbpasswd\fR accesses the local smbpasswd file +directly, thus enabling changes to be made even if smbd is not +running. +.SH "OPTIONS" +.TP +\fB-a\fR +This option specifies that the username +following should be added to the local smbpasswd file, with the +new password typed (type <Enter> for the old password). This +option is ignored if the username following already exists in +the smbpasswd file and it is treated like a regular change +password command. Note that the user to be added must already exist +in the system password file (usually \fI/etc/passwd\fR) +else the request to add the user will fail. + +This option is only available when running smbpasswd +as root. +.TP +\fB-x\fR +This option specifies that the username +following should be deleted from the local smbpasswd file. + +This option is only available when running smbpasswd as +root. +.TP +\fB-d\fR +This option specifies that the username following +should be disabled in the local smbpasswd +file. This is done by writing a 'D' flag +into the account control space in the smbpasswd file. Once this +is done all attempts to authenticate via SMB using this username +will fail. + +If the smbpasswd file is in the 'old' format (pre-Samba 2.0 +format) there is no space in the users password entry to write +this information and so the user is disabled by writing 'X' characters +into the password space in the smbpasswd file. See \fBsmbpasswd(5) +\fRfor details on the 'old' and new password file formats. + +This option is only available when running smbpasswd as +root. +.TP +\fB-e\fR +This option specifies that the username following +should be enabled in the local smbpasswd file, +if the account was previously disabled.
