samba - Jun 2012 - Unable to join Samba PDC with version 3.6.5 (works with 3.3.15)

Hello Folks,

I am unable to join any linux Samba clients to my Samba-3.6.5 PDC with clients
running 3.4.x, 3.5.x, or 3.6.x versions.   However, 3.3.x works fine and so do
my Windows clients.

When I do a 'net rpc join' I get a 'successfuly joined domain'
message with say 3.6.5, but I am unable to authenticate on the domain
thereafter.

Any clues?  I can send the configurations (smb.conf) of the server and client if
it can help solve this mystery.  I suspect I'm just missing a configuration
directive on the client side... but I can't seem to find any reference in
the documentation.

On the Samba-3.6.5 PDC, we're using a LDAP backend.

Thanks in advance!
