[Samba] Re: ldapsearch and getent passd/group with nss winbind differs
There is one "UNIX attribute" tab and one "Members Of" tab. During some tests we discover the following facts = In "UNIX attribute" tab: winbind is only interested in the UID field -> in ldap tree the attribute "uidnumber". If you're talking SFU, it doesn't use uidnumber. It uses attribute msSFU30UidNumber and displays UID on the Unix Attributes tab. I don't have a Windows 2003 R2 for comparison. Are you really using SFU (Services For Unix 3.0) or do you have the newer 2003 R2? I use 2003 R2 and did install the "Unix plugin" for AD schemata extension from Windows component setup. The other attributes from "UNIX attribute" tab are written to ldap tree, but not used by winbind on linux side. For example we set the following parameter in smb.conf: winbind nss info = sfu Of course we could define our own template bash/home with the "template home" and "template shell" parameter, but its better the "sfu" will work, so we would configure this parameter by the tab. Winbind only uses this parameter when it creates a Unix account. Which shouldn't happen for your AD domain members if your AD is mapped correctly. winbind uses this parameter only if "it" creates a unix account ? In case if i create a unix account with "adduser" on terminal ? The mapping seems to be correctly if i have a look at "getent passwd + getent group" The "primary Group" is written to the ldap tree but not used by winbind on the unix side. I meant the "primary Group" text field from: "UNIX attribute" tab seems to be NOT used by winbind. The "primary group" which you can set: by clicking the button "primary group" in "Members Of" tab IS USED by winbind perfectly. Iam sorry if my explanation wasnt clear at my last posting. # net ads testjoin Join is OK # wbinfo -i forest\\jdoe FOREST\jdoe:*:525:100:John Doe:/home/jdoe:/bin/bash # getent passwd|grep jdoe FOREST\jdoe:*:525:100:John Doe:/home/jdoe:/bin/bash # getent group|grep 100 FOREST\domain users:x:100: You can set the value msSFU30Gecos and winbind will report it, otherwise "Display Name" is used. In "Members Of" tab: In this tab you can choose a group from a list and there is a button you could set a Unix primary group by klicking. This will be read by winbind only. But this have no force to the primary group ID on the "UNIX attribute" tab. What do you say ? Did we configure something wrong ? Is this the normal function ? I needed to use the "idmap config" values: idmap domains = FOREST idmap config FOREST:readonly = yes idmap config FOREST:backend = ad idmap config FOREST:range = 0 - 2 idmap config FOREST:schema_mode = sfu idmap alloc backend = tdb idmap alloc config:range = 5-50999 and of course in nsswitch.conf: passwd: compat winbind group: compat winbind some people like to use "files" instead of "compat", but that's about NIS semantics and doesn't matter to winbind. winbind separator = / winbind enum users = yes winbind enum groups = yes winbind cache time = 60 idmap backend = ad idmap uid = 6000-27000 idmap gid = 600-7000 template shell = /bin/bash template homedir = /home/%U winbind use default domain = yes winbind refresh tickets = yes allow trusted domains = yes winbind nss info = sfu template My nsswitch.conf is like yours. We want to use the "compat" mode because we hope we could exclude some users for login. This isnt possible to winbind ?! Alternatively i know pam_require. Do you know an opportunity to do this task ? Is there a part of documentation where the ldap attributes are shown which are used by winbind ? Or do i have to look up this at source code :-) Thanks a lot for your posting, Andy Regards, Doug -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba

[Samba] Performance problem when tagging mp3 files
Hello you, maybe you can help me with a performance problem i´ve when tagging mp3 files from a windows vista system where the files are located on a samba share hosted by a suse linux 9.3. these are my performance relevant settings. # These settings are a suggestion for a local network. Cf. section # 'socket options' in the man page of smb.conf and socket(7). time server = yes getwd cache = yes level2 oplocks = yes preserve case = yes case sensitive = no map archive = no socket options = SO_KEEPALIVE IPTOS_LOWDELAY TCP_NODELAY the performance when transferring large files is great in my opinion. I´ve hand stopped 72 seconds for transferring about 800MB to a share (in a 100MBit network). But tagging mp3 files is incredibly slow. For example: If i just change the album tag of 10 mp3 files and save the result, saving lasts about 30 seconds or more. And my samba log (with log level 2) shows something like: [2008/08/24 10:01:04, 2] smbd/open.c:open_file(352) js opened file mp3/Rock/U2/U218 Singles/U2 And Green Day - U218 Singles - 17 - The Saints Are Coming.mp3 read=Yes write=No (numopen=1) [2008/08/24 10:01:04, 2] smbd/close.c:close_normal_file(344) ftp closed file mp3/Rock/U2/U218 Singles/U2 And Green Day - U218 Singles - 17 - The Saints Are Coming.mp3 (numopen=0) [2008/08/24 10:01:04, 2] smbd/open.c:open_file(352) js opened file mp3/Rock/U2/U218 Singles/U2 And Green Day - U218 Singles - 17 - The Saints Are Coming.mp3 read=Yes write=Yes (numopen=1) [2008/08/24 10:01:07, 2] smbd/close.c:close_normal_file(344) ftp closed file mp3/Rock/U2/U218 Singles/U2 And Green Day - U218 Singles - 17 - The Saints Are Coming.mp3 (numopen=0) [2008/08/24 10:01:07, 2] smbd/open.c:open_file(352) js opened file mp3/Rock/U2/U218 Singles/U2 And Green Day - U218 Singles - 17 - The Saints Are Coming.mp3 read=Yes write=No (numopen=1) there is this strange 3 seconds delay on the write operation?
