                       Hello,

                        
                        In a first time  I configured the
                        synchronisation between one AD and one

                        389DS. it is working fine. Now, I would like to
                        mount a new one 389DS

                        that will be a replica read-only of the first :

                        I read this doc :

                        http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/8.2/html/Administration_Guide/Managing_Replication-Configuring_Multi_Master_Replication.html

                        http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/7.1/html/Administrators_Guide/sync.htm#2876133

                         From this picture I want something more simple
                        like :

                        
                        Consumer read-only (replica)<----->
                        Supplier Read-Write <----Sync--->

                        Windows AD

                        
                        I don't see how I can configure the replication
                        on the Supplier

                        The supplier sync with AD a database that
                        contains user and group of the AD

                        The supplier has one more database with Unix
                        user and group (I can

                        enable replica on this database and it is
                        working (it is a single

                        master) , I got the replication  of this
                        database on the consumer)

                        
                        The problem is for the first database (AD) that
                        is a dedicated consumer

                        for the Windows AD. I dont see how configure as
                        a single master to do

                        the replication to the consumer.

                        Support or explanation will help me

                        Thanks,

                        
                   It's documented in the section 9.5.1
                    and 9.5.2.
                
                Yes, but I don't find the answer to my question in the
                documentation.

                In my configuration of the replica settings are :

                In replica role : "Dedicated consumer" (Must  I change
                it to "Multiple Master" ? )

                Common settings : Replica ID = 65535  (now I read this
                must be a digit between 1 and 65534) Must I change it
                and what are therefore if I change the value
                ?
            
          
        Only writable masters use the ReplicaID.  For a hub or dedicated
        consumer, use 65535.

      
      Actually the 389ds syncing with the AD is in "dedicated consumer".
      So do you mean that I need to change from dedicated consumer to
      (single or multi) Master ?
    It needs to be a supplier, which means it needs to either be a hub
    or a master.  If you want it to be read-only from clients, use hub,
    otherwise use master.

    but
      what will be the consequence of this change on the syncing with
      the AD , is there a possibility that the synchronisation doesn't
      work anymore ?

      
                    Question, what version of AD are you using?
                      Because I was able to configure Windows Sync
                      agaisnt AD 2008r2 but it doesn't work with 2003. I
                      wrote a patch to the windows sync pluging to get
                      it working.
                  
                
                I use 2008r2 
            
          
          Yes, let it configured as "Multiple Master". If you have a
          read-only consumer, the master could be configured as
          "multi-master"  or "single master".
          

           If don't remember the allowed range for ID, but don't
            use 65535 to be sure.

            
          Thanks for the information about 2008r2. 
          

          Regards,
           Diego
