Since these have unique results, you should create another map file and do not try to reuse another. Note: using LDAP is certainly allowed, just make sure the source is highly available. Recommend a local, replicated LDAP server for such a purpose You may wish to dump these to a hashed file via script if you do not want to store the relay server in the LDAP. Brian
