RE: [Samba] Corrupted userid in mail folders - Crisis
Hi, another thing popes to my mind, check if a nscd process is running on your box. if yes stop it and remove it from the startup-scripts. It is not compatible with with samba and windbindd and may create strange effects. Christoph Yes, nscd was running, but I have stopped it now. What is nscd? Also, further to our discussion before, the userid actually get's changed Look at this: [EMAIL PROTECTED] root]# ls -l /home/RHENGHS/canhal total 12 drwx-- 7 monsla Domain Users 4096 Aug 17 13:48 Maildir/ drwx-- 2 monsla Domain Users 4096 Feb 23 2002 tmp/ drwxr-xr-x 2 monsla Domain Users 4096 Jun 20 2002 webpage/ [EMAIL PROTECTED] root]# ls -ln /home/RHENGHS/canhal total 12 drwx-- 7 10585 1 4096 Aug 17 13:48 Maildir/ drwx-- 2 10585 1 4096 Feb 23 2002 tmp/ drwxr-xr-x 2 10585 1 4096 Jun 20 2002 webpage/ [EMAIL PROTECTED] root]# getent passwd canhal canhal:x:10167:1::/home/RHENGHS/canhal:/bin/bash So you can see that the correct user should be 10167, not 10585 Also SMB hangs after a few hours.

RE: [Samba] Corrupted userid in mail folders - Crisis
A really silly question, but bear with me please... How do I remove a service from the cron.d directory? I can just delete the nscd file, but what if I want to run it again? Of course I can copy it somewhere into a backup dir to get it there again later, but it there is standard practice for disabling a service?

RE: [Samba] Corrupted userid in mail folders - Crisis
I've run the script that I posted earlier, and everything seems fine. I'll monitor the situation over the next hour or more to see what happens. The only effective change I made is that I stopped the nscd service.

I'm going to run it again, since I change the slow hub to a switch and stopped the nscd service. The I'll see what happens. Roland Also SMB hangs after a few hours. When I left last night, everything had been running fine for about 2 hours. When I got to work this morning, no-one was authenticated. When I tried to ls a user dir, I got not response. On issuing the reboot command I saw on the console that there was no process SMB. Here are the SMB messages in syslog. How was your samba installed? Was it compiled from source or are the package(s) from your distribution installed?

I can just delete the nscd file, but what if I want to run it again? Of course I can copy it somewhere into a backup dir to get it there again later, but it there is standard practice for disabling a service? To stop a SuSE service: rc'servicename' stop ie: rcnscd stop For Red Hat Linux: /etc/rc.d/init.d/nscd stop Note: The path may be: /etc/init.d/'servicename' or /etc/rc.d/'servicename', or /etc/rc.d/init.d/'servicename' depending on your version and Linux vendor. To configure the service to prevent it from restarting when the server is rebooted: chkconfig nscd off To list all services and the status of each: chkconfig list Enjoy! - John T.

It is not compatible with with samba and windbindd and may create strange effects. Christoph Yes, nscd was running, but I have stopped it now. What is nscd? The Name Service Caching Daemon. It can cause symptoms similar to what you are seeing. Do not run nscd with Samba, but also make certain that winbindd_idmap.tdb is not being deleted. - John T.

RE: [Samba] Corrupted userid in mail folders - Crisis
I run a network for a school as part of my duties and cannot resolve this problem. If I haven't given enough technical detail, please let me know, but I really need help with this. Thanks in advance Roland -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Roland Giesler Sent: 21 September 2004 14:48 To: [EMAIL PROTECTED] Subject: [Samba] Corrupted userid in mail folders I have a Mandrake 10.0 Official server running Samba3, Shorewall, Squid 2.5, Postfix and Courier-IMAP. Samba uses winbind to authenticate mail and proxy users against a windows 2000 ADS server. I get corruption happening in the user's home directories and elsewhere. The directory ownership changes all the time. One moment a dir belongs to roland:Domain Users and the next moment it's marjou:elahyl. The group and userid change, causing absolute havoc with mail delivery as wrong mail lands in people's mailboxes and users cannot be authenticated. My senior support technician is on honeymoon so I'm stuck. Restarting services makes no difference. If I run getent passwd username the results are 100% correct. Also for getend group groupname. Has anynone expereinced this or know of a fix. I'm somewhat clueless on some aspects, like I cannot check the version of Samba, since the doesn't appear to be a command switch for this. thanks Roland -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba
RE: [Samba] Corrupted userid in mail folders - Crisis
Christoph Scheeder asked Hi, 1.) is this a new installation No, it was Mandrake 8.2 box, but was recently upgraded to Mandrake 10. 2.) if not what was changed when the failure first occured? Thing were running fine, at least that's what it appeared like. Then sporadically people started getting authentication error when logging into their IMAP mailboxes. Next the deputy principal reported that she had received other people's mail. So I ran the following script to reset all the folders: #!/bin/bash export IFS=: echo Auto-creating home directories for windows domain users getent passwd|grep :10[0-9][0-9][0-9]|while read USER FLAG USERUID USERGID USER_LONG USERHOME USERSHELL; do if [ -e $USERHOME ]; then echo Setting ownership of existing $USERHOME chown -R $USERUID.$USERGID $USERHOME else echo Creating $USERHOME for $USER with $USERUID/$USERGID mkdir $USERHOME; cp -a /etc/skel/* $USERHOME chown -R $USERUID.$USERGID $USERHOME fi done; After this the all appeared to be fine. But then a few hours later thing got even worse. Even squid's cache file got wrong ownership and stopped squid from spawning child processes. Eventually the machine hangs and I cannot see why. Btw is the a log where hanging processes can be logged? Or could I enable logging to syslog? I restarted the machine about an hour ago and all folders seem fine now 3.) please could you verify if the numeric user/group id's of the files in question change? use ls -ln on the files for this check. I would bet the numeric user/group id's don't change even when the usernames mapped to them change. please verify and post the result back to me. I'm checking that now. As soon as I have an id that's changed, I test and post the result.
