[X2Go-User] Failure negotiating the session in stage '7'. Wrong version or invalid session authentication cookie.

[Kjell Otto]

Hi Roland,

have you seen what's mentioned here:
http://developer.berlios.de/bugs/?func=detailbug&bug_id=18258&group_id=2978

Wether it helps or not, it would be great to see the server side of this,
so please post the corresponding entries of your /var/log/syslog after
configuring the x2goserver for debugging(set it in
/etc/x2go/x2goserver.conf).

Nevertheless, the only Cookies I can think used by x2go are the MIT magic
cookies of X... maybe try to delete the .Xauthority of the user trying to
log in and retry...

Greetings,
@Kjellski
