I'm pretty much an LDAP-ignoramus.  However, if you have a copy of the
data through a drbd mirror, then most databases can deal with it without
using external synchronization methods.  However, I have heard that LDAP
has it's own synchronization methods, and they are probably easier to
configure, and perhaps lower-bandwidth.

Certainly you can't do load sharing when using the drbd approach.
