I'm glad that this works at your side as well!

Please, provide more information about all versions that you use. For
example, I'm using X2goclient 3.01-13 under Windows7 as client, because the
latest version 3.01-14 doesn't work.

You have to investigate deeper. Try these tips:

1. Change your ssh logging by changing inside file: /etc/ssh/sshd_config -
LogLevel INFO change to LogLevel DEBUG3
Then watch the authentication log: tail -f /var/log/auth.log .And login
again
(I know that you said that it authenticate successfully, still check this
out)

2. Login locally on the Ubuntu server with: USERNAME at DOMAIN (although you
can't see them through gdm or kdm), if you can successfully login to the
domain locally. If you have troubles with that, then the problem is with
likewise. BTW, are you using likewise-open? How you've configured it? Using
domainjoin-gui? Can you see from System -> Administration -> Active
Directory Membership. (You can see that with Local user of Ubuntu).

3. Try to login with SSH client (like putty for windows) using again
USERNAME at DOMAIN, and the password. Then check if this login is successful.

4. If authentication is good, but there is blank/black screen, then try
another: OS, Client, Client version. As I said above, the latest version
doesn't work in my scenario. Hint: Don't try to connect with client from the
same server, as it is not possible. If you use Windows, try to find other
OS, install other (virtual if possible) Windows, Linux, whatever is easy for
you.

Bottom line: It seem to be client problem, but you need to do further
investigations to find out.

Best Regards
Ivan
