[X2Go-User] Not Working with changes in PAM

[segurah h]

Hi :

I was using x2go server and it worked fine until I follow this guide
in order to add my linux box (the x2go server) to a Microsoft Active
Directory ( https://help.ubuntu.com/community/ActiveDirectoryWinbindHowto
) , now I can't initiate a session from x2goclient to this box but can
do perfectly ssh sessions with Unix local users also mircrosoft
domains users, export X display works fine. Putting x2go server in
debug mode shows :

Also, at the client side (x2goclient), the error is :

Error: The remote NX proxy closed the connection
Error: Failure negotiating the session in stage '7
Error: Wrong version or invalid session authentication cookie
Session: Terminating session at .....

A popup message says :

x2go -51
The remote proxy closed the connection while negotiating the session.
This may be due to the wrong authentication credentials passed to the
server.


What do you think that can be happening? I can't understand. Any help?

Best regards,
