Identity Manager and Identity Portal Integration is working and connecting however when we attempt to run the "SigmaViewGroupTask" It is failing with a Authentication error. 
Identity Portal 1.6.1
We were able to resolve this by leaving SSO enabled. Without it enabled it was failing with authentication. Please see the error below.
