[Samba] ntlm_auth = NT_STATUS_NO_LOGON_SERVERS: No logon servers (0xc000005e)
I had to downgrade samba on a rh5.5 instance due to ntlm_auth not working
properly: https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=561325
Now, when I add the computer to the domain ('net ads join ?U
Administrator') it seems to work, is visible on the AD interface, but the
logs show an error:

And wbinfo gives me nothing ? so I am assuming there is a problem:
[root at rhclient samba]# wbinfo -u
[root at rhclient samba]# wbinfo -g
[root at rhclient samba]#
When trying to do a ntlm_auth, I get a funky error as well:
[root at rhclient samba]# ntlm_auth --request-nt-key
--domain=VMSECLAB.CABLE.COMCAST.COM --username=user
password:
NT_STATUS_NO_LOGON_SERVERS: No logon servers (0xc000005e)
Yet, there is a login server in the samba.conf, and dns/reverse dns works:
[root at rhclient samba]# grep 'password server' /etc/samba/smb.conf
password server = ad.vmseclab.cable.com
[root at rhclient samba]# nslookup ad.vmseclab.cable.com
Server: 10.252.159.138
Address: 10.252.159.138#53
Name: ad.vmseclab.cable.com
Address: 10.252.159.138
[root at rhclient samba]# nslookup 10.252.159.138
Server: 10.252.159.138
Address: 10.252.159.138#53
138.159.252.10.in-addr.arpa name = ad.vmseclab.cable.com.
The samba logs show this when trying to ntlm_auth:
==> /var/log/samba/log.winbindd-dc-connect <=[2010/11/11 16:16:55, 1]

Has anyone seen this, or have any clue what could be happening? It seems like my
DC does not have cldap open/working? What port does that run over? If its normal
ldap(389), I can telnet to that fine.
I am out of ideas, any help would be appreciated. Thanks.

[Samba] ntlm_auth = NT_STATUS_NO_LOGON_SERVERS: No logon servers (0xc000005e)
security = domain or security = user? I had problems with winbind using security = user.. I can't remember properly it's been a while..
