+ + Samba FAQ + +<author>Paul Blackman, <tt>ictinus@lake.canberra.edu.au</tt> + +<date>, v 0.5 + +<abstract> This is the Frequently Asked Questions (FAQ) document for +Samba, the free and very popular SMB server product. An SMB server +allows file and printer connections from clients such as Windows, +OS/2, Linux and others. Current to version 1.9.16. Please send any +corrections to the author. +</abstract> + +<toc> + +<sect> General Information<p> <label id="general_info"> + +All about Samba - what it is, how to get it, related sources of +information, how to understand the version numbering scheme, pizza +details + +<sect1> What is Samba? <p> <label id="introduction"> + +Samba is a suite of programs which work together to allow clients to +access to a server's filespace and printers via the SMB (Server +Message Block) protocol. Initially written for Unix, Samba now also +runs on Netware, OS/2 and VMS. + +In practice, this means that you can redirect disks and printers to +Unix disks and printers from Lan Manager clients, Windows for +Workgroups 3.11 clients, Windows NT clients, Linux clients and OS/2 +clients. There is also a generic Unix client program supplied as part +of the suite which allows Unix users to use an ftp-like interface to +access filespace and printers on any other SMB servers. This gives the +capability for these operating systems to behave much like a LAN +Server or Windows NT Server machine, only with added functionality and +flexibility designed to make life easier for administrators. + +The components of the suite are (in summary): + +<itemize> + +<item> smbd, the SMB server. This handles actual connections from +clients, doing all the file, permission and username work + +<item>nmbd, the Netbios name server, which helps clients locate +servers, doing the browsing work and managing domains as this +capability is being built into Samba + +<item>smbclient, the Unix-hosted client program + +<item>smbrun, a little 'glue' program to help the server run external +programs + +<item>testprns, a program to test server access to printers + +<item>testparms, a program to test the Samba configuration file for +correctness + +<item>smb.conf, the Samba configuration file + +<item> smbprint, a sample script to allow a Unix host to use smbclient +to print to an SMB server + +<item> documentation! DON'T neglect to read it - you will save a great +deal of time! + +</itemize> + +The suite is supplied with full source (of course!) and is GPLed. + +The primary creator of the Samba suite is Andrew Tridgell. Later +versions incorporate much effort by many net.helpers. The man pages +and this FAQ were originally written by Karl Auer. + +<sect1> What is the current version of Samba? <p> <label id="current_version"> + +At time of writing, the current version was 1.9.16. If you want to be +sure check the bottom of the change-log file. <url +url="ftp://samba.anu.edu.au/pub/samba/alpha/change-log"> + +For more information see <ref id="version_nums" name="What do the +version numbers mean?"> + +<sect1> Where can I get it? <p> <label id="where"> + +The Samba suite is available via anonymous ftp from +samba.anu.edu.au. The latest and greatest versions of the suite are in +the directory: + +/pub/samba/ + +Development (read "alpha") versions, which are NOT necessarily stable +and which do NOT necessarily have accurate documentation, are +available in the directory: + +/pub/samba/alpha + +Note that binaries are NOT included in any of the above. Samba is +distributed ONLY in source form, though binaries may be available from +other sites. Recent versions of some Linux distributions, for example, +do contain Samba binaries for that platform. + +<sect1> What do the version numbers mean? <p> <label id="version_nums"> + +It is not recommended that you run a version of Samba with the word +"alpha" in its name unless you know what you are doing and are willing +to do some debugging. Many, many people just get the latest +recommended stable release version and are happy. If you are brave, by +all means take the plunge and help with the testing and development - +but don't install it on your departmental server. Samba is typically +very stable and safe, and this is mostly due to the policy of many +public releases. + +How the scheme works: + +1) when major changes are made the version number is increased. For +example, the transition from 1.9.15 to 1.9.16. However, this version +number will not appear immediately and people should continue to use +1.9.15 for production systems (see next point.) + +2) just after major changes are made the software is considered +unstable, and a series of alpha releases are distributed, for example +1.9.16alpha1. These are for testing by those who know what they are +doing. The "alpha" in the filename will hopefully scare off those who +are just looking for the latest version to install. + +3) when Andrew thinks that the alphas have stabilised to the point +where he would recommend new users install it, he renames it to the +same version number without the alpha, for example 1.9.16. + +4) inevitably bugs are found in the "stable" releases and minor patch +levels are released which give us the pXX series, for example +1.9.16p2. + +So the progression goes: + + 1.9.15p7 (production) + 1.9.15p8 (production) + 1.9.16alpha1 (test sites only) + : + 1.9.16alpha20 (test sites only) + 1.9.16 (production) + 1.9.16p1 (production) + +The above system means that whenever someone looks at the samba ftp +site they will be able to grab the highest numbered release without an +alpha in the name and be sure of getting the current recommended +version. + +<sect1> What platforms are supported? <p> <label id="platforms"> + +Many different platforms have run Samba successfully. The platforms +most widely used and thus best tested are Linux and SunOS. + +At time of writing, the Makefile claimed support for: + + * SunOS + * Linux with shadow passwords + * Linux without shadow passwords + * SOLARIS + * SOLARIS 2.2 and above (aka SunOS 5) + * SVR4 + * ULTRIX + * OSF1 (alpha only) + * OSF1 with NIS and Fast Crypt (alpha only) + * OSF1 V2.0 Enhanced Security (alpha only) + * AIX + * BSDI + * NetBSD + * NetBSD 1.0 + * SEQUENT + * HP-UX + * SGI + * SGI IRIX 4.x.x + * SGI IRIX 5.x.x + * FreeBSD + * NeXT 3.2 and above + * NeXT OS 2.x + * NeXT OS 3.0 + * ISC SVR3V4 (POSIX mode) + * ISC SVR3V4 (iBCS2 mode) + * A/UX 3.0 + * SCO with shadow passwords. + * SCO with shadow passwords, without YP. + * SCO with TCB passwords + * SCO 3.2v2 (ODT 1.1) with TCP passwords + * intergraph + * DGUX + * Apollo Domain/OS sr10.3 (BSD4.3) + +<sect1> How can I find out more about Samba? <p> <label id="more"> + +There are two mailing lists devoted to discussion of Samba-related +matters. There is also the newsgroup, comp.protocols.smb, which has a +great deal of discussion on Samba. There is also a WWW site 'SAMBA Web +Pages' at http://samba.canberra.edu.au/pub/samba/samba.html, under +which there is a comprehensive survey of Samba users. Another useful +resource is the hypertext archive of the Samba mailing list. + +Send email to listproc@samba.anu.edu.au. Make sure the subject line is +blank, and include the following two lines in the body of the message: + + subscribe samba Firstname Lastname + subscribe samba-announce Firstname Lastname + +Obviously you should substitute YOUR first name for "Firstname" and +YOUR last name for "Lastname"! Try not to send any signature stuff, it +sometimes confuses the list processor. + +The samba list is a digest list - every eight hours or so it +regurgitates a single message containing all the messages that have +been received by the list since the last time and sends a copy of this +message to all subscribers. + +If you stop being interested in Samba, please send another email to +listproc@samba.anu.edu.au. Make sure the subject line is blank, and +include the following two lines in the body of the message: + + unsubscribe samba + unsubscribe samba-announce + +The From: line in your message MUST be the same address you used when +you subscribed. + +<sect1> Something's gone wrong - what should I do? <p> <label id="wrong"> + +[#] *** IMPORTANT! *** [#] +DO NOT post messages on mailing lists or in newsgroups until you have +carried out the first three steps given here! + +Firstly, see if there are any likely looking entries in this FAQ! If +you have just installed Samba, have you run through the checklist in +DIAGNOSIS.txt? It can save you a lot of time and effort. + +Secondly, read the man pages for smbd, nmbd and smb.conf, looking for +topics that relate to what you are trying to do. + +Thirdly, if there is no obvious solution to hand, try to get a look at +the log files for smbd and/or nmbd for the period during which you +were having problems. You may need to reconfigure the servers to +provide more extensive debugging information - usually level 2 or +level 3 provide ample debugging info. Inspect these logs closely, +looking particularly for the string "Error:". + +Fourthly, if you still haven't got anywhere, ask the mailing list or +newsgroup. In general nobody minds answering questions provided you +have followed the preceding steps. It might be a good idea to scan the +archives of the mailing list, which are available through the Samba +web site described in the previous +section. + +If you successfully solve a problem, please mail the FAQ maintainer a +succinct description of the symptom, the problem and the solution, so +I can incorporate it in the next version. + +If you make changes to the source code, _please_ submit these patches +so that everyone else gets the benefit of your work. This is one of +the most important aspects to the maintainence of Samba. Send all +patches to samba-bugs@samba.anu.edu.au, not Andrew Tridgell or any +other individual and not the samba team mailing list. + +<sect1> Pizza supply details <p> <label id="pizza"> + +Those who have registered in the Samba survey as "Pizza Factory" will +already know this, but the rest may need some help. Andrew doesn't ask +for payment, but he does appreciate it when people give him +pizza. This calls for a little organisation when the pizza donor is +twenty thousand kilometres away, but it has been done. + +Method 1: Ring up your local branch of an international pizza chain +and see if they honour their vouchers internationally. Pizza Hut do, +which is how the entire Canberra Linux Users Group got to eat pizza +one night, courtesy of someone in the US + +Method 2: Ring up a local pizza shop in Canberra and quote a credit +card number for a certain amount, and tell them that Andrew will be +collecting it (don't forget to tell him.) One kind soul from Germany +did this. + +Method 3: Purchase a pizza voucher from your local pizza shop that has +no international affiliations and send it to Andrew. It is completely +useless but he can hang it on the wall next to the one he already has +from Germany :-) + +Method 4: Air freight him a pizza with your favourite regional +flavours. It will probably get stuck in customs or torn apart by +hungry sniffer dogs but it will have been a noble gesture. + +<sect>Compiling and installing Samba on a Unix host<p> +<label id="unix_install"> + +<sect1>I can't see the Samba server in any browse lists!<p> +<label id="no_browse"> + +*** Until the FAQ can be updated, please check the file: +*** ftp://samba.anu.edu.au/pub/samba/BROWSING.txt +*** for more information on browsing. + +If your GUI client does not permit you to select non-browsable +servers, you may need to do so on the command line. For example, under +Lan Manager you might connect to the above service as disk drive M: +thusly: + + net use M: \\mary\fred + +The details of how to do this and the specific syntax varies from +client to client - check your client's documentation. + +<sect1>Some files that I KNOW are on the server doesn't show up when I +view the files from my client!<p> +<label id="missing_files"> + +<sect1>Some files on the server show up with really wierd filenames when +I view the files from my client!<p> +<label id="strange_filenames"> + +If you check what files are not showing up, you will note that they +are files which contain upper case letters or which are otherwise not +DOS-compatible (ie, they are not legal DOS filenames for some reason). + +The Samba server can be configured either to ignore such files +completely, or to present them to the client in "mangled" form. If you +are not seeing the files at all, the Samba server has most likely been +configured to ignore them. Consult the man page smb.conf(5) for +details of how to change this - the parameter you need to set is +"mangled names = yes". + +<sect1>My client reports "cannot locate specified computer" or similar<p> +<label id="cant_see_server"> + +This indicates one of three things: You supplied an incorrect server +name, the underlying TCP/IP layer is not working correctly, or the +name you specified cannot be resolved. + +After carefully checking that the name you typed is the name you +should have typed, try doing things like pinging a host or telnetting +to somewhere on your network to see if TCP/IP is functioning OK. If it +is, the problem is most likely name resolution. + +If your client has a facility to do so, hardcode a mapping between the +hosts IP and the name you want to use. For example, with Man Manager +or Windows for Workgroups you would put a suitable entry in the file +LMHOSTS. If this works, the problem is in the communication between +your client and the netbios name server. If it does not work, then +there is something fundamental wrong with your naming and the solution +is beyond the scope of this document. + +If you do not have any server on your subnet supplying netbios name +resolution, hardcoded mappings are your only option. If you DO have a +netbios name server running (such as the Samba suite's nmbd program), +the problem probably lies in the way it is set up. Refer to Section +Two of this FAQ for more ideas. + +By the way, remember to REMOVE the hardcoded mapping before further +tests :-) + +<sect1>My client reports "cannot locate specified share name" or +similar<p> +<label id="cant_see_share"> + +This message indicates that your client CAN locate the specified +server, which is a good start, but that it cannot find a service of +the name you gave. + +The first step is to check the exact name of the service you are +trying to connect to (consult your system administrator). Assuming it +exists and you specified it correctly (read your client's doco on how +to specify a service name correctly), read on: + + * Many clients cannot accept or use service names longer than +eight + characters. + * Many clients cannot accept or use service names containing +spaces. + * Some servers (not Samba though) are case sensitive with service +names. + * Some clients force service names into upper case. + +<sect1>My client reports "cannot find domain controller", "cannot log +on to the network" or similar <p> +<label id="cant_see_net"> + +Nothing is wrong - Samba does not implement the primary domain name +controller stuff for several reasons, including the fact that the +whole concept of a primary domain controller and "logging in to a +network" doesn't fit well with clients possibly running on multiuser +machines (such as users of smbclient under Unix). Having said that, +several developers are working hard on building it in to the next +major version of Samba. If you can contribute, send a message to +samba-bugs! + +Seeing this message should not affect your ability to mount redirected +disks and printers, which is really what all this is about. + +For many clients (including Windows for Workgroups and Lan Manager), +setting the domain to STANDALONE at least gets rid of the message. + +<sect1>Printing doesn't work :-(<p> <label id="no_printing"> + +Make sure that the specified print command for the service you are +connecting to is correct and that it has a fully-qualified path (eg., +use "/usr/bin/lpr" rather than just "lpr"). + +Make sure that the spool directory specified for the service is +writable by the user connected to the service. In particular the user +"nobody" often has problems with printing, even if it worked with an +earlier version of Samba. Try creating another guest user other than +"nobody". + +Make sure that the user specified in the service is permitted to use +the printer. + +Check the debug log produced by smbd. Search for the printer name and +see if the log turns up any clues. Note that error messages to do with +a service ipc$ are meaningless - they relate to the way the client +attempts to retrieve status information when using the LANMAN1 +protocol. + +If using WfWg then you need to set the default protocol to TCP/IP, not +Netbeui. This is a WfWg bug. + +If using the Lanman1 protocol (the default) then try switching to +coreplus. Also not that print status error messages don't mean +printing won't work. The print status is received by a different +mechanism. + +<sect1>My programs install on the server OK, but refuse to work properly<p> +<label id="programs_wont_run"> + +There are numerous possible reasons for this, but one MAJOR +possibility is that your software uses locking. Make sure you are +using Samba 1.6.11 or later. It may also be possible to work around +the problem by setting "locking=no" in the Samba configuration file +for the service the software is installed on. This should be regarded +as a strictly temporary solution. + +In earlier Samba versions there were some difficulties with the very +latest Microsoft products, particularly Excel 5 and Word for Windows +6. These should have all been solved. If not then please let Andrew +Tridgell know. + +<sect1>My "server string" doesn't seem to be recognised<p> +<label id="bad_server_string"> + +my client reports the default setting, eg. "Samba 1.9.15p4", instead +of what I have changed it to in the smb.conf file. + +You need to use the -C option in nmbd. The "server string" affects +what smbd puts out and -C affects what nmbd puts out. In a future +version these will probably be combined and -C will be removed, but +for now use -C + +<sect1>My client reports "This server is not configured to list shared +resources" <p> <label id="cant_list_shares"> + +Your guest account is probably invalid for some reason. Samba uses the +guest account for browsing in smbd. Check that your guest account is +valid. + +See also 'guest account' in smb.conf man page. + +<sect1>Log message "you appear to have a trapdoor uid system" <p> +<label id="trapdoor_uid"> + +This can have several causes. It might be because you are using a uid +or gid of 65535 or -1. This is a VERY bad idea, and is a big security +hole. Check carefully in your /etc/passwd file and make sure that no +user has uid 65535 or -1. Especially check the "nobody" user, as many +broken systems are shipped with nobody setup with a uid of 65535. + +It might also mean that your OS has a trapdoor uid/gid system :-) + +This means that once a process changes effective uid from root to +another user it can't go back to root. Unfortunately Samba relies on +being able to change effective uid from root to non-root and back +again to implement its security policy. If your OS has a trapdoor uid +system this won't work, and several things in Samba may break. Less +things will break if you use user or server level security instead of +the default share level security, but you may still strike +problems. + +The problems don't give rise to any security holes, so don't panic, +but it does mean some of Samba's capabilities will be unavailable. +In particular you will not be able to connect to the Samba server as +two different uids at once. This may happen if you try to print as a +"guest" while accessing a share as a normal user. It may also affect +your ability to list the available shares as this is normally done as +the guest user. + +Complain to your OS vendor and ask them to fix their system. + +Note: the reason why 65535 is a VERY bad choice of uid and gid is that +it casts to -1 as a uid, and the setreuid() system call ignores (with +no error) uid changes to -1. This means any daemon attempting to run +as uid 65535 will actually run as root. This is not good! + +<sect>Common client questions<p> <label id="client_questions"> + +<sect1>Are any Macintosh clients for Samba<p> <label id="mac_clients"> + +In Rob Newberry's words (rob@eats.com, Sun, 4 Dec 1994): + +The answer is "No." Samba speaks SMB, the protocol used for Microsoft +networks. The Macintosh has ALWAYS spoken Appletalk. Even with +Microsoft "services for Macintosh", it has been a matter of making the +server speak Appletalk. It is the same for Novell Netware and the +Macintosh, although I believe Novell has (VERY LATE) released an +extension for the Mac to let it speak IPX. + +In future Apple System Software, you may see support for other +protocols, such as SMB -- Applet is working on a new networking +architecture that will --> -- make it easier to support additional +protocols. But it's not here yet. + +Now, the nice part is that if you want your Unix machine to speak +Appletalk, there are several options. "Netatalk" and "CAP" are free, +and available on the net. There are also several commercial options, +such as "PacerShare" and "Helios" (I think). In any case, you'll have +to look around for a server, not anything for the Mac. + +Depending on you OS, some of these may not help you. I am currently +coordinating the effort to get CAP working with Native Ethertalk under +Linux, but we're not done yet. + + +<sect1>"Session request failed (131,130)" error<p> <label id="sess_req_fail"> + +The following answer is provided by John E. Miller: + +I'll assume that you're able to ping back and forth between the +machines by IP address and name, and that you're using some security +model where you're confident that you've got user IDs and passwords +right. The logging options (-d3 or greater) can help a lot with that. +DNS and WINS configuration can also impact connectivity as well. + +Now, on to 'scope id's. Somewhere in your Win95 TCP/IP network +configuration (I'm too much of an NT bigot to know where it's located +in the Win95 setup, but I'll have to learn someday since I teach for a +Microsoft Solution Provider Authorized Tech Education Center - what an +acronym...) [Note: It's under Control Panel | Network | TCP/IP | WINS +Configuration] there's a little text entry field called something like +'Scope ID'. + +This field essentially creates 'invisible' sub-workgroups on the same +wire. Boxes can only see other boxes whose Scope IDs are set to the +exact same value - it's sometimes used by OEMs to configure their +boxes to browse only other boxes from the same vendor and, in most +environments, this field should be left blank. If you, in fact, have +something in this box that EXACT value (case-sensitive!) needs to be +provided to smbclient and nmbd as the -i (lowercase) parameter. So, if +your Scope ID is configured as the string 'SomeStr' in Win95 then +you'd have to use smbclient -iSomeStr [otherparms] in connecting to +it. + +<sect1>How do I synchronise my PC's clock with my Samba server? <p> +<label id="synchronise_clock"> + +To syncronize your PC's clock with your Samba server: + +* Copy timesync.pif to your windows directory + * timesync.pif can be found at: + http://samba.canberra.edu.au/pub/samba/binaries/miscellaneous/timesync.pif +* Add timesync.pif to your 'Start Up' group/folder +* Open the properties dialog box for the program/icon + * Make sure the 'Run Minimized' option is set in program +'Properties' + * Change the command line section that reads \\sambahost to reflect +the name + of your server. +* Close the properties dialog box by choosing 'OK' + +Each time you start your computer (or login for Win95) your PC will +synchronize it's clock with your Samba server. + +<sect1>Problems with WinDD, NTrigue, WinCenterPro etc<p> +<label id="multiple_session_clients"> + +All of the above programs are applications that sit on an NT box and +allow multiple users to access the NT GUI applications from remote +workstations (often over X). + +What has this got to do with Samba? The problem comes when these users +use filemanager to mount shares from a Samba server. The most common +symptom is that the first user to connect get correct file permissions +and has a nice day, but subsequent connections get logged in as the +same user as the first person to login. They find that they cannot +access files in their own home directory, but that they can access +files in the first users home directory (maybe not such a nice day +after all?) + +Why does this happen? The above products all share a common heritage +(and code base I believe). They all open just a single TCP based SMB +connection to the Samba server, and requests from all users are piped +over this connection. This is unfortunate, but not fatal. + +It means that if you run your Samba server in share level security +(the default) then things will definately break as described +above. The share level SMB security model has no provision for +multiple user IDs on the one SMB connection. See security_level.txt in +the docs for more info on share/user/server level security. + +If you run in user or server level security then you have a chance, +but only if you have a recent version of Samba (at least 1.9.15p6). In +older versions bugs in Samba meant you still would have had problems. + +If you have a trapdoor uid system in your OS then it will never work +properly. Samba needs to be able to switch uids on the connection and +it can't if your OS has a trapdoor uid system. You'll know this +because Samba will note it in your logs. + +Also note that you should not use the magic "homes" share name with +products like these, as otherwise all users will end up with the same +home directory. Use \\server\username instead. + +<sect1>Problem with printers under NT<p> <label id="nt_printers"> + +This info from Stefan Hergeth +hergeth@f7axp1.informatik.fh-muenchen.de may be useful: + + A network-printer (with ethernetcard) is connected to the NT-Clients +via our UNIX-Fileserver (SAMBA-Server), like the configuration told by + Matthew Harrell harrell@leech.nrl.navy.mil (see WinNT.txt) + + 1.) If a user has choosen this printer as the default printer in his + NT-Session and this printer is not connected to the network + (e.g. switched off) than this user has a problem with the SAMBA- + connection of his filesystems. It's very slow. + + 2.) If the printer is connected to the network everything works fine. + + 3.) When the smbd ist started with debug level 3, you can see that +the + NT spooling system try to connect to the printer many times. If +the + printer ist not connected to the network this request fails and +the + NT spooler is wasting a lot of time to connect to the printer +service. + This seems to be the reason for the slow network connection. + + 4.) Maybe it's possible to change this behaviour by setting different +printer properties in the Print-Manager-Menu of NT, but i didn't try +it yet. + +<sect1>Why are my file's timestamps off by an hour, or by a few hours?<p> +<label id="dst_bugs"> + +This is from Paul Eggert eggert@twinsun.com. + +Most likely it's a problem with your time zone settings. + +Internally, Samba maintains time in traditional Unix format, +namely, the number of seconds since 1970-01-01 00:00:00 Universal Time +(or ``GMT''), not counting leap seconds. + +On the server side, Samba uses the Unix TZ variable to convert +internal +timestamps to and from local time. So on the server side, there are +two +things to get right. + + 1. The Unix system clock must have the correct Universal +time. + Use the shell command "sh -c 'TZ=UTC0 date'" to check this. + + 2. The TZ environment variable must be set on the server + before Samba is invoked. The details of this depend on the + server OS, but typically you must edit a file whose name is + /etc/TIMEZONE or /etc/default/init, or run the command `zic +-l'. + + 3. TZ must have the correct value. + + 3a. If possible, use geographical time zone settings + (e.g. TZ='America/Los_Angeles' or perhaps + TZ=':US/Pacific'). These are supported by most + popular Unix OSes, are easier to get right, and are + more accurate for historical timestamps.

The format for a date +is + `Mm.n.d', which specifies the dth day (0 is +Sunday) + of the nth week of the mth month, where week 5 +means + the last such day in the month. The format +for a + time is [h]h[:mm[:ss]], using a 24-hour clock. + + Other Posix string formats are allowed but you don't +want + to know about them. + +On the client side, you must make sure that your client's clock and +time zone is also set appropriately. [[I don't know how to do this.]] +Samba traditionally has had many problems dealing with time zones, due +to the bizarre ways that Microsoft network protocols handle time +zones. A common symptom is for file timestamps to be off by an hour. +To work around the problem, try disconnecting from your Samba server +and then reconnecting to it; or upgrade your Samba server to +1.9.16alpha10 or later. + +<sect1> How do I set the printer driver name correctly? <p> +<label id="printer_driver_name"> + +Question: +> On NT, I opened "Printer Manager" and "Connect to Printer". +> Enter "\\ptdi270\ps1" in the box of printer.

This tells the client what driver to use. For +example, I have: + + printer driver = HP LaserJet 4L + +and NT knows to use the right driver. You have to get this string +exactly right. + +To find the exact string to use, you need to get to the dialog box in +your client where you select which printer driver to install. The +correct strings for all the different printers are shown in a listbox +in that dialog box. + +You could also try setting the driver to NULL like this: + + printer driver = NULL + +this is effectively what older versions of Samba did, so if that +worked for you then give it a go. If this does work then let me know +and I'll make it the default.
