Yes, they work. I installed some similar solutions ten years ago. Then i began using freeipa and never looked back. > Alexander, when I mention migration, I think of the following actions > :> 1.

After that you'll want to tune openldap and add all the needed indexes. You should think about replication. You should think about security. You should think about ldap administration.
