If you have that kind of need for high availability, you could provide better redundancy in other ways.  Why do you need MMR for this?  You could simply setup a 389 consumer, and use something like LVS to provide automatic failover, or even just do a DNS switch to point to the consumer if ever needed.  I have nothing against ubuntu, its a nice desktop distro, but it wouldn't be my choice on a mission critical server.

hope this helps..

Hi,

It's ok.as per my request, how can i proceed further ?

Shall i go ahed as per the Redhat site ? or any other method to implementation ? 

Note: more then 2500 users are, right now accessing web applications through single 389-ds on my Ubuntu LTS. I am planning to go for one more server, if main server will go down,another one will automatically provide auth service.

I am struck for multimaster replication and pls guide me further...
