I have added Grouper integration to my CAS server. I am able to get the grouperGroups attribute returned, but I need to refine it. How can I narrow down the groups returned to only those in a particular stem? I've tried
cas.authn.attribute-repository.grouper.parameters=scope=app:Experience:service:roles
which generated a stack trace, so I modified it to
cas.authn.attribute-repository.grouper.parameters=scope:app:Experience:service:roles
This didn't seem to do anything, so I tried
cas.authn.attribute-repository.grouper.parameters=stemName=app:Experience:service:roles
which also didn't seem to work. Any pointers in the right direction would be very much appreciated.
