I've 2 servers in MirrorMode, a part of the tree wil also be partially replicated to 3 slaves.
Do I really need an LDAP proxy or Load balancer(s) so writes are only directed to one server?
In our LDAP, the number of writes will be very very low, most of them will be reads (authentication, ssh keys, puppet nodes...)
Any benefit in using 'normal' n multimaster instead of MirrorMode?
