[Samba] Samba4 Domain Member Server "Getent show diferents UID"
Rowland, a question. "is to copy idmap.ldap from the first DC to all others and then keep them in sync, the other is to use RFC2307 attributes." I can do the same with my member server? Maybe it works, or not for beign a member server. Maybe i can change my Member Server to a Domain Controller and after use idmap, sync. Its ok? Analista Inf.
