[X2Go-User] Seahorse via X2Go Custom Desktop: Insufficient Priviliges

[Alexanderstr Miete]

Dear X2go users and team,

As it seems there is no easy solution to allow the X2Go session user have
the same privileges in Ubuntu (when connecting via: connect with  "Custom
Desktop" Command: MATE) as a local user (i.e. via VNC)

Some issues can be solved via editing settings in

/var/lib/polkit-1 , for example to allow the remote user to access Network
settings.

However, I did not manage to allow Seahorse to show / properly work with
passwords when accessed during an X2Go session:

When accessing via VNC, network credentials can be edited and stored in
Seahorse.

With X2Go access via connect with "Custom Desktop" Command: MATE , all
these sections seem to be missing in Seahorse even though the same user is
used,  and Caja (the file manager in Mate) seems to requests a password for
SMB access every time.

See attached screenshot.

Help would be much appreciated.  How can Seahorse get the same privileges
during that X2Go session as for a local session/VNC?

Thanks
