    LDAP: Add enum request with custom connection
    
    This commit changes the enumerate-sdap-domain request to accept a
    connection context per object that can be enumerated. Internally in the
    request, an sdap_id_op is also created per enumerated object type.
    
    This change will allow i.e. users to be enumerated using GC connection,
    while keeping the LDAP connection for groups and services.
