[Samba] Samba 2.2.5-10, W2K PDC and Winbind - Authentication issues
I've gotten passed the problem I had with joining the domain. However, I
am still having problems with the authentication of domain user accounts
against the samba server.
wbinfo -u shows my users from the domain correctly.
wbinfo -g does the same for my domain groups.
getent passwd shows the domain users as expected.
wbinfo -t shows a good trust.
wbinfo -a allows me to authenticate any user (although I've noticed only
plain text seems to work?)
NOTE: If I add entries into the smbpasswd in the format of domain+user and
set the password then all works as expected, save of course the fact I have
to manually add the users which basically defeats the purpose of setting up
winbind?
Any ideas, thoughts, suggestions, or glasses filled with hard liquor are
welcome. I see the following quite frequently in the logs on Samba, but
nothing on the audit logs of the PDC. "connect_to_domain_password_server:
machine SERVER rejected the tconX on the IPC$ share. Error was :
NT_STATUS_ACCESS_DENIED."
PDC is a W2K SP2 Advanced Server.
Samba is on RedHat 7.1 Kernel 2.4.9-34
When I try to access a share, or even browse the root of the same server I
get various examples of the following in my log.smbd:
