ad_get_group_id

Returns the group_id cookie value. Returns 0 if the group_id cookie is missing, if the user is not logged in, or if the user is not a member of the group.

Source code:

    # 1 verifies the user_id cookie 
    # 2 gets the group_id cookie
    # 3 verifies that the user_id is mapped to group_id
