Hmm, NSS is this linux stuff for auth modules if memory serves me right.
While I don't know if it is implemented as inefficient as many other things
there it has of course an overhead because i cannot fire up such a
specialized query as qmail-ldap can. As long as you hav an index on mail,
mailalternateaddress, uid and of course cn qmail-ldap + OpenLDAP is just
flying on a BSD system, it shouldn't be that worse on linux and will be bad
on Slowlaris.

Clustering is a bit misleading for this qmail-ldap technique. You want a big
NetApps Filer and mount the users maildirs on each machine via NFS.

Unix is very simple, but it takes a genius to understand the simplicity.
