likewise remote users authentication failure

likewise remote users authentication failure

I have been trying to add my ubuntu box to the windows AD domain. On that
box, I see the the domain users when i do
lw-enum-users
And if I am already logged into my local user, i can 'su' to a domain user
and that works. However, when I switch user, I have to do
'sudo su domain\user'
which gives
su: Authentication failure (Ignored)
and continues to switch me to that user. If I just do a normal su, it
gives me Authentication Failure
What I can't do, is
ssh 'domain\user'@host
to get into the ubuntu server
When I do, I get the following
Sep 30 15:20:02 ubuntu-trac sshd[1420]: error: PAM: Authentication failure
for domain\user from 10.22.1.220
