I have a RHEL 5 system, with Samba 3.0.33 installed, that _used_ to
authenticate against the corporate Active Directory system without any
problems. However, about a month ago the connection broke, but the users
didn't complain until some time went buy. I've spent quite a few hours
trying to reconnect this system, but nothing works. I do not believe it is
a simple configuration problem, as it used to work... and am afraid that
something changed on the corporate domain controllers. Unfortunately,
corporate doesn't believe in non-Windows solutions to anything and will not
support me in this effort. They also don't support an NFS services, which
are critical for my user community. sigh...
Kerberos authentication still works;
--------------------------------------------------------------------------------------
# kinit -V username
Password for username@WKG.COMPANY.COM:
Authenticated to Kerberos v5
[root@palsrv6] klist
Ticket cache: *FILE:/tmp/krb5cc_0*
Default principal: username@WKG.COMPANY.COM
Valid starting Expires Service principal
03/16/09 09:42:42 03/16/09 19:42:51 krbtgt/WKG.COMPANY.COM@WKG.COMPANY.COM
renew until 03/17/09 09:42:42
--------------------------------------------------------------------------------------
Samba can talk to the Primary Domain Controller as a client, but doesn't
seem to
recognize the PDC as a server.
