Hi,
We are running Samba-2.2.6pre2 as a PDC with Win2kSP2-clients and we had
the same problem running samba-2.2.5 and Win2k. We had NT4-client
running previous versions of samba-2.2.x and have never had the same
problem.
Samba is compiled from source on Solaris8 running YP.
We have everything up and running but sometimes users get a dialog-box
just saying "Access denied" when they try to access any
network-resources. They have logged in ok and can open some files before
the problem appears. The problem doesn't seem to be user-depedent, it
can happen to any user on any machine randomly.
Is this a known bug or something you can do anything about? Killing the
smbd-process makes the win2k-client reconnect and everything works
again. The user can open files and work.
If you truss the smbdprocess when the problem have ocurred you see:
root at dune:>truss -p 12325
*** SUID: ruid/euid/suid = 0 / 0 / 60001 ***
*** SGID: rgid/egid/sgid = 0 / 0 / 60001 ***
Before the problem:
root at dune:>truss -p 14245
*** SUID: ruid/euid/suid = 0 / 0 / 18097 ***
*** SGID: rgid/egid/sgid = 0 / 0 / 18097 ***
60001 matches the user and group nobody from /etc/passwd and 18097
matches the current users UID and GID from YP.
The samba-log says (log level = 2) when the error occured:
