[Bug 341816] Re: samba PANIC: failed to set uid

[Jan Schneider]

Yes, i have seen a lot of similar bug reports too, but all of them were
unresolved.

When the problem appeared we checked a lot of configuration issues.
The problem seems NOT to be user or client specific.
The users where the PANIC appeared:
 - had a unix account
 - a samba account with the same uid
 - no special ulimits set
 - no group membership which seems to be responsible for the problem
 - su <user> did work, opening files as this user did work, no messages like: to many open files...

# getent passwd 11789
diehl:x:11789:11700::/home/diehl:/bin/bash

# pdbedit -L -u diehl
diehl:11789:

# su - diehl -c 'ulimit -u'
30720

# getent group 11700
<groupname>:x:11700:

# net groupmap list | grep <groupname>
<groupname> (<SID>) -> <groupname>

Samba worked without any problems if there were less than about 100
clients/users connected.

Volker Lendecke from SerNet proposed to set "change notify = no" as a
workaround, which we did not really test.

If you need more information, please let me know, but since this server
acts as a domain controller in an productive environment I cannot
reproduce the bug.
