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

The way it is currently implemented, slapo-memberof(5) needs the memberOf attribute to be populated from scratch. If you enable this overlay on an existing database, you need to repopulate the database, or at least to delete and re-add the group entries. A function that allows to enable the overlay on an existing database needs to be added. I suggest you file an ITS for a feature request.
