The LTSP user session is running on the server through ssh -X. The shutdown will need to be executed on the client. LTSP is using xprops as a mechanism for the server to notify the client to execute something. It is indeed a hack, but that's the "standard" way we do it in LTSP. That's also the way localapps are implemented.
So when the user initiates shutdown, either from the indicator-session applet or from the session dialog (tested and working), an xprop is set. LTSP sessions are remote (ssh) sessions, so ConsoleKit does not consider them active. So a logoff is performed instead of a shutdown/reboot. After the logoff, the LTSP display manager reads the xprop and sees if it needs to reboot or halt the client. One better way to resolve this would be to implement appropriate dbus hooks so that the session bus running on the server "talks" to the system bus running on the client. Unfortunately, I don't think any LTSP developer is working on implementing this, and I don't even know if it can be accomplished. In previous Ubuntu releases there was a patch in fusa that was hiding the reboot/shutdown menus for LTSP clients. This isn't used anymore, so now those menus are there but are just performing "logoff" instead, confusing the users. So I'm not aware of any other realistic way to have working shutdown/reboot menus in LTSP, other than the attached patch.
