    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:

    Best,
