I was looking through list archives and a few weeks ago, someone posted some configurations for the memberOf overlay.  I modified the configurations slightly and it looks like everything is installed (with no errors) and working, but when run an ldapsearch, it does not return the memberOf.  Below is the install and configuration method.  Any guidance on what to change or error logs to look at?
 
Thx Bill
