Mmm, you mean if two master replica's are disconnected by a network failure? Guess this might cause
some problems, but if you simply have a master replica down for the duration of a password update
as soon as it restarts it should sync up with it's peer?? This should cater for server redundency but
maybe leaves some issues open with relation to network connectivity...

My worry is if two independent client update to two independent,
disconnected LDAP peers.  This particularly applies when we are doing an
atomic increment in LDAP, like we do in IDMAP, and like a good 'add user
script' should do.
