Syncrepl question

[Ivan Ordonez <iordonez@nature.berkeley.edu>]

Hi all,

We have a small size domain with about 500 users and computers.  We are 
using Samba with Openldap integration to authenticate user login and 
file sharing.  Our setup is consist of 3 servers running Gentoo Linux - 
1PDC and 2BDCs.  As for replication, we are still using "slurpd".  Any 
changes or modification is done through the PDC which replicates the 
changes to BDC1, then from BDC1, it then goes down to BDC2 - it's like a 
chain.

We want to start using "syncrepl" soon as a way to replicate our 
database but I'm not sure were to start.  We want to setup all of our 
machine to sync with each other everyday, and not worry which machine is 
use to make changes, modification, etc....  I'm not sure which syncrepl 
function to use to achieve what we want to do.  Is "N-Way Multi Master 
replication" the correct choice to do this?  We are using "BDB" database 
on each servers, and would like to achieve this with minimal downtime if 
possible.  What is the best way to do this?  Please advise.

Any help is greatly appreciated.
