If memo is about what should happen when a User from collab1 ( collab.humanbrainproject.eu ) try to login with his user MitreId to Iam
Case 1 : User have an account in MitreId but not in IAM
Case 1.1 : User has a personal email ( not institutional ) such as gmail.com
When he attemps to loggin on an existing service from the new collab, lets take https://wiki.ebrains.eu
Nothing happen, Iam reject it, this username is unknow from IAM, and we don't look for it in MitreId because it's an unauthorized email
Possible action : You should Register by Getting Access or ask the support to create you exceptionnaly an account with personal email
