When I assign a bundle to an Active Directory user group, it doesn't get deployed. Only bundles assigned to the user's primary group get installed.

Reproducing this:
1. create two bundles (the easiest is web url's in the users start menu).
2. assign one of them to the "Domain Users" group (all users are member of this and have this as their primary group).
3. assign the other to an other group of which the user is a member.

result: only the first app gets installed

4. switch the users primary group in AD and refresh (or logff)

result: now only the other app gets installed
