samba - Mar 2006 - SFU Permission Denied

This appears to be an old problem, but is a complete show stopper for us
at the moment.

We are trying to access an NFS file system, via Samba, from a WinXP
client. Within Windows itself everything is fine, but when accessing the
shares from within an SFU cshell, an error is returned when a file is
created. The file is successfully created, but a "Permission Denied"
error is returned.

We receive the "Unable to validate owner sid" message in the log file.

Has any found a solution to this problem yet?

We are using Samba 3.0.21c and SFU 3.5.

Thanks,

Mat

Debug level 10 log please ? I'm guessing that the problem
might be the uid/gid's on the file can't be looked up in
the LSA. What authentication/domain system are you using ?

Jeremy,

We have found a solution to our problem, although it is not ideal. We
have used the "force unknown acl user" flag in the smb.conf file,
setting it to "yes". We have used this at the moment as a quick fix to
get around the problem, as we have not set up any authentication
mechanism (winbind) within Samba.

I'll send you the log file when I get a change to copy it over.

Cheers,

Mat
