Grouper Users - Open Discussion List

["T-Heetderks" <>]

I am trying to setup GROUPER 2.5 from the deployed Docker container (latest)
with Auth via Shib to our campus IDP. When I complete the Auth, I get an ERROR
message: Your username could not be found in the system as an entity.
LOGGED:
POST /grouper/grouperExternal/public/UiV2Public.postIndex?
function=UiV2Public.error&code=authenticatedSubjectNotFound HTTP/1.1" 200 818
How do I either make it recognize Auth from Shib as a valid Subject -OR-
manually enter the Shib user as a valid Subject

Thanks for the help!!
