Splitting data for replication

[Jorge Ortiz Claver <jortiz@idsk.com>]

Hi,

I have a ldap database I'd like to replicate to different slaves. Data 
is organized as follows:

                                      o=mycompany
                                                  |
                         -----------------------------------------
                        |                         |                     
   |
                ou=domain1         ou=domain2         ou=domain3

Replication would be made at domains level, replicating domain1data to 
one server, domain2 to another one and so on. I know I can't have all 
the data in the same database so I need to chop the data out into 
different databases.

Here is my questions: what is the better way to distribute the data 
among different databases but keep a "virtual" view of the whole tree 
for clients? I mean I don't want the clients to send three or four 
queries in order to search for a user. I'd like to make organization 
transparent to clients.

Another requirement is (I guess that's not too complex) I need to 
maintain some domains data out of the main server so for example, I'd 
need to maintain domain3 data in a different server and replicate it to 
the main server.

Any idea, suggestion or advice?

Thanks in advance
