[Samba] Intermittent guest user instead of normal user

[Mike Fedyk]

Hi,

Sometimes when a user connects to a samba share they will be logged in as
the guest user(shown in smbstatus) on samba "Version 2.2.3a-6 for Debian".

This has been happening for a while now, but now it's happening on our new
server and I want to get it fixed.

Also, most times this only happens with one specific share while the rest of
the shares use the correct user, but it happens with other shares too.

Has anyone else seen this too?  I'm sending this message while I'm starting
to find out why it's happening here.

I'm posting my smb.conf and the file it references.  The "zbackup" share is
the one acting up at the moment. I can post more information if needed.

Thanks,

Mike
