Linux Mail Server Setup and Howto Guide

Hi, i'm running CentOS4.7 x64  and I'm having a hard time getting the netgroup filtering to work via PAM and the 389-Directory server.

I followed the same concept of editing nsswitch.conf to check netgroups and /etc/pam.d/system-auth to define my /etc/security/access.netgroup.com.  all pulled from the 389-directory server webpage.  I've got it all working fine in CentOS5 but in CentOS4.7 it seems to ignore my statements in nsswitch and system-auth to check which users can login based on their group.

Thanks, those two kbase articles are actually what I used to configure the CentOS4 host, but I thought i need the pam_ldap module in those files as well which was causing it not to work.
