Hi, Running CentOS 5.4 with stock OpenLDAP distro 2.3.43. Both classes, posixgroup and groupofnames are structural causing conflicts if one wants to use both. And while RFC2307bis is deleted by IETF, RFC2307 doesn't seem to have the same traction (or, does it)? So, what's a good option? Simply switch posixgroup to AUX in /etc/openldap/schema/nis.schema? Thanks, Siddhartha
