Hi!

I didn't find any information about this on the net so I made my own expand
function.
In short the function takes the users and groups added to the contact
selector and performs a search in the ad if the userobject is a group. The
search returns a adspath to the group in the ad, which can be used to access
the property member which contains the users in the group. Removing the group
from the contact selector while adding the new users solved the problem.

Best regards
