[Samba] Samba 3.0.23c + Win2K AD, can't mount shares (PANIC: internal error)
Hi,
I've got a big problem since my new samba servers are in 3.0.23c
version, no problems before.
The server is only a file server and domain member in a Win2K Active
Directory domain (4 replicated DC, 1 domain, no forest).
My problem:
Anytime I try to connect a share through any kind of client (MacOS
cifs client, smbclient, windows win2K pro, ...) the client can't
mount the share and I've got this in my user log on the samba server :

Sounds like the groupmap change "problem" in 3.0.23 but I can't
find
anything on the web that can help me solving that problem.
I'm not even sure that my problem come from the groupmap changes in
the 3.0.23 samba version.
Best regards,
Sebastien.
