[Freeipa-devel] [PATCH] assign unique replica ID to all instances

[Rob Crittenden]

Ensure that every replica gets a unique replication ID. Otherwise
changes won't propogate between all replicas.

I create a new entry, cn=replication, cn=etc, that will hold the next 
replication ID to assign. When a new replica is being created it 
requests this number, then increments it and writes it back.

This does leave some amount of exposure to a collision but I think the 
risk is quite low. Creating replicas is a very uncommon activity.
