Yes. After more than a year running Postfix 2.1.5 on a given RHAS3 site
and having 1150+ users really hammering OpenLDAP 2.2.17 both with
ns_ldap and LDAP searches, no problems whatsoever, present uptime 90+
days (downtimes due to RHAS3 kernel updates).
All Postfix local(8) delivery is local. And no use whatsoever is made of
nss for LDAP.
This is to OP:
