Thanks Sebastian Me again, I hot fixed the problem for me by adding and deleting a dummy user a couple of times: # for i in `seq 0 50 ` ; do # net rpc user add username -U root%geheim # net rpc user delete username -U root%geheim # done but I still guess this is a bug in the net command.

[Samba] net rpc user add produces duplicate SID
Hi list, The task is to move an old samba installation (ubuntu with samba 3.0 brachch) to a new debian installation with samba 3.3.9. Both setups work as pdcs and have an ldap backend which I try to move from one setup to the next. In this new setup I tried to ldapsam:editposix = yes. Therefore I also installed winbind. I moved the domain SID and the local SID to the new pdc and filled the ldap directory with all users and machines from the old machine. I can access the smb via smbclient, id user works and getent passwd, etc. BUT when I try to add a new user with # net rpc user add newusername the user gets a SID which is already used by a machine account. The command responds with Faild to add user 'newusername' with: No such user. # pdbedit -L reports this user and this machine account with ldapsam_getsampwsid: More than one user with SID [S-1-5-21]. Failing. count=2. Deleting the user via # net rpc user delete newusername works. I know how to increase the used uid but I don't know to let winbind use the next free RID. Extracts from my smb.conf: passdb backend = ldapsam ldap suffix is set ldap admin dn is set ldap user/group/machine/idmap suffix are set ldapsam:trusted = yes ldapsam:editposix = yes idmap uid = 1 - 2 idmap gid = 1 - 2 Hope anyone can help and merry christmas to the list Sebastian -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
[Samba] Samba freezes server when writing 50MB MS Word document (sometimes)
Hi list for a couple of days we have the problem that our samba pdc server (ubuntu 8.04 LTS [kernel 2.6.24-24] with 3.0.28a samba package) freezes sometimes when someone saves a specific word document (about 50MB) from MS Word. It's not always the same person. Saving the document - as nearly any huge MS Office document - takes some time, about one minute (guessed). First the server gets really slow. Some user programs on clients fail to write. The CPU usage of the smb process of the user writing the document goes up to nearly 100%. After a while it's not possible to log on to the server - even locally. It asks for a password but there won't be a prompt. Sometimes there is nothing on the console/screen. Hitting a button does not change a thing. It's not possible to kill the process. Another thing is that there are a couple of smbd processes for one user (see attached user smbd log). When rebooting the server it does not shut down properly. I guess the process blocks the harddrive thus it cannot be unmounted. A ALT+Print+u and ALT+Print+b helps. ### This is what the syslog says: Jul 3 15:01:44 [..] BUG: soft lockup - CPU#1 stuck for 11s!

If it's not possible to kill smbd, even with -9, this really sounds like a kernel problem. Look for example at https://bugs.launchpad.net/linux/+bug/254326 Volker Hi Volker thanks for your reply. You are right, it sounds more or less like that. The difference is that the kernel was running for quite a while without any problems and we are using a different board (Intel server board S3210SHLX with Core2Duo CPU). Being Saturday today it was possible to install the lasted Ubuntu server kernel update 8.04.3 (Linux xx 2.6.24-24-server #1 SMP Tue Jun 30 21:03:25 UTC 2009 i686 GNU/Linux). I tried to reproduce the fail but with just me in the office and no real traffic it's hard to do so. Maybe it just helped. I will wait and see.
