[Samba] Samba PANIC

Sun Sep 9 01:06:18 GMT 2007

Hi all,
Hope somebody can help. I am obviously not a samba guru...

I've installed a new server and tried to migrate my existing configuration and users..
I'm using FC6 and Version 3.0.24-7.fc6.

Unfortunately when I performed the install on the new server, I didn't make sure my user
UID and GID's where the same as the previous server which resulted in all sorts of odd
behaviour particulary with the joining of the domains.

I then manually altered all the user UID's and GID's (redoing groups almost entirely) to
reflect the original configuration.

Lo and behold it worked. After redoing all the 'Machine trust accounts' I'm now in a
situation where Samba seems to be working HOWEVER.....

After logon when I first try to access a share samba does a dump and I get an error
message. On retrying all seems to work.

Below is a copy of the dump messages and smb.conf .. Any help would be appreciated
