I’m happy to announce my latest how-to, Setting up a Samba PDC setup using OpenLDAP on CentOS, is now available in the wiki.
Setting up a Samba PDC setup using OpenLDAP on CentOS describes how to setup a Samba PDC using OpenLDAP as the user database instead of the default flat files Samba uses.  It provides full sample configuration files and instructions on how to install and configure the smbldap tools.
I’ll be adding helper scripts for maintaining users, groups and machines at the command just like the ones in the Setting up a small scale Samba PDC on CentOS how-to.
