[imp] load balancing

[Brian Clark]

We use BigIP from F5 to load balance our mail (smtp, pop, imap, ldap) 
traffic amongst three servers. We've got two of them that work in a 
fail-over configuration. If the primary fails, the secondary takes over 
for it.

However, I haven't figured out the best way load balance an IMP 
installation. I use LDAP to store all of my user information, and all of 
my user mailboxes are stored on an NFS server. How do I store _all_ of 
the user-specific configuration information for IMP in an LDAP 
directory?  Also, for true redundancy, would I need to install a 
database on each of my Horde/IMP servers? I use PostgreSQL for the one 
server that I have running IMP right now.
