Hello list, Iam using Samba4 alpha18 with Debian Squeeze. Mi primary
domain have Windows Server 2003 and my Secundary Domain have Samba4. When
i create a user in active directory user and computer in Windows Server, i
can see the user in active directory user and computer in samba4, and when
i create a user in samba4 i can see this user en active directory windows
server. the principal problem is in Active Directory Sites and Services.
When a replicate from Windows to Samba 4 sometime is succefull, and
sometime give some error. but when i replicate from samba4 to windows
server, the replicate take very much time,  so so 6 hours.
somebody have some procedure to make replication between windows and samba4.
