If you are serving one site (it sounds like you are) then Martin's solution
makes perfect sense.

If you have geographically dispersed users, then you may wish to put an OUD in
each location fronted by a load balancer that is geographically aware.

LeRoy,

OUD in bidirectional replication  is the way to go.
You can avoid the load balancer as you can put all OUDs into your ldap.ora:
DIRECTORY_SERVERS=(ldap-server:389, raffles:400:636)

Folks,

I am looking for some advice on how to set up this high availability OUD
environment.  We are currently running OID 11 on a single Oracle Linux 7.2
physical server.  This is a single point of failure so we are looking at
creating this new env.

We are looking at using VMware Oracle Linux 7.*, Oracle ASM 12.2, and Oracle
RAC.  I am planning on setting up a 2 node RAC to start and can scale up if
needed later.  For OUD, I was planning on adding 2 servers with OUD 12
installed on each and replicating to each other.  I was then going to add a
load balancer – OVD proxy server – to the front end to handle the failover.

What are people doing for high availability for OVD proxy server?

LeRoy
