Distribution Groups in alternate Global Addresslists



we are running E2k3SP1 Enterprise on W2k3, we have configured multiple global
address lists (for each company a GAL),based on the companyname but the
disadvantage of this construction we cannot see any distribution list ...
Is there a way to solve this problem that a user can see only the
distribution lists / users / contacts he is authorised to see .

thanx
