OpenLDAP Servers and Availability

[Ishklight <ishklight@gmail.com>]

Hi,

I want to set up openldap servers to be available all the time.
In short, if one goes down, the other should automatically pick up and service the requests.
I looked at Master-Slave with Syncrepl and Multi-master configurations. I don't understand which configuration could help me.

Also, how would I test my requirement? 

Is it possible to set up highly available openLDAP servers? Please suggest.

Thanks in advance,


Regards,
Imran
