AdminUI: In 5.64 new basic search shows group names to users who, according to ACLs, don't have access to those groups
The new basic search ('Find Contacts') in 5.64 that uses SK correctly restricts visibility of contacts for users with access limited by ACLs, but still shows the group names that those users should not be able to see. If the user then searches those groups, they appear to have zero contacts which is confusing. Users with access limited by ACLs should only be able to see those group names that they have access to. Disabling the AdminUI extension and restoring the old basic search solves the problem - those groups are not then displayed.
