how users and subsites (gruoups) are related?
what tables are used? acs_rels and user?
acs_rels.object_id_one and acs_rels.object_id_two does not hold the object_id from the acs_objects table to subsites.
Neither the API to get the gruop_id work as expected
subsite::get -array subsite_info
set group_id [group::get_id -group_name $subsite_info(name)]
