Technical Tip

Problem

A Forum reader recently asked:

"I'm trying to mirror what the AD Group Entitlement is doing, except for Groups in eDirectory. I created the Loopback driver and created an entitlement named "Group" underneath that. The entitlement is an exact match of the AD entitlement and seems to be working fine with setting up the RBE. The only thing in the filter is the DirXML-EntitlementRef on the
Subscriber Channel set to Notify. I'm trying to figure out what I'm doing wrong or missing in the add/remove from group logic.

It's selecting the correct RBE; I'm just not sure how to get it to select the correct group."

And here's the response from Father Ramon ...

Solution

Setting up a loopback driver with a group entitlement for eDirectory is significantly different than for the AD driver. Here is an export of a configuration that works:
