[X2Go-User] X authorization issues

[Michael DePaulo]

With tcsh, I have observed:

1. X2Go Client for Windows Kerberos 5 (GSSAPI) authentication failing.
2. Sessions not being cleaned up after a user logs out of the desktop
environment. (But the session being gracefully terminated from the
user's perspective.) To see if this is happening, run:
sudo x2golistsessions_root

I need to try to reproduce these issues at home.
