I was reading this other topic, and was wondering if the solution found there might not help out with your issue here: Unable to get membership group after aggregation - #2 by ismaelmoreno1
I believe the main issue here is that it is not currently working with “groupOfMembers”, which is different from the “groupOfUniqueNames”, “posixGroupsd”, “group” and “nisNetGroup”.
Does anyone else have experience using “groupOfMembers”?
