Real HA cluster implementation

[pgentoo]

Can't openldap be configured via pam so standard "useradd" and similar commands add to ldap instead of /etc/{passwd,shadow,group}

I'm wondering if the same thing could be accomplished without actually changing ispcp... ?

I'm also setting up an HA environment for another project i'm wokring on, but once it's done i'll piggyback my hosting setup on it, so i'm very interested.
