disable shutdown button on logout

[Eberhard Roloff]

Hi,

I am using more and more the XFCE 4.4 version that comes with SuSE 10.2.

Anything is running great.
Now I installed an LTSP (Linux Terminal Server Project) Server and I
would like to offer xfce sessions to the remote booting LTSP Users as a
lightweight alternative to KDE.

Now, in KDE is was easy for me to disable ordinary Users from shutting
down the machine. However I could not manage to find such a setting in
xfce. As a result, any "ordinary" user that uses XFCE can shutdown the
"local" machine via the "shutdown" button on Logout, which happens to be
 the Terminal Server in case the User logs in from an LTSP Terminal.

I searched any config setting I could find and used google, all to no avail.

Any hint how I could disable "shutdown" for "ordinary" users will be
appreciated.

Please accept my apologies if this has been discussed before and I
missed to find the obvious.

Thanks and kind regards
Eberhard
