We have implemented onea functionality via the Core Service and we want to control thehave this functionality toonly available to only one SDL Tridion group (For ee.g. TridionGrp) and all others should get an unauthorized error.
We are able to check for the users who are directly part of this TridionGrp however how can we check if a user part of another group (For ee.g. TridAccess) and TridAccesswhile that other group is part of TridionGrp.
So how can we recursively check the user membership in order to validate the access?
