the idea once was to create a meta package, for ubuntu that incorporated a couple of functions...
1 pam-ldapauth to auth users agains zentyal users&groups
2 pam-mount to auto mount required shares.
3 thunderbird if mail module enabled
4 some scripts a way to auto configure them to work with the local zentyal server.
5 an agent a way to check what desktops you have and what thair status is... (basic info).
up to this date lack of priority (taking ubuntu serriously) prevented this from being develloped..
