At the moment, we have a single LDAP server which we are using with LDAP Account Manager for web-based object management and Atlassian Crowd for authentication. The LDAP server is queried directly by other servers for UNIX-level authentication, i.e. SSH and group membership.
I'm looking at introducing a second LDAP server and I'm leaning towards choosing mirror mode as the replication methodology. Since the only writes to LDAP come via LAM or Crowd, and these are both web-based, I think I could set up an almost identical server to the one I have at the moment and use a system like Amazon's Route 53 DNS service with health checks to allow me to redirect users off to the second server if the first server fails.
Just curious, why would you do "mirror mode" MMR vs just plain MMR? Do you feel you have a specific requirement that only one master ever receive the write traffic?
