How do I change my affiliation?

I am studying/working at multiple faculties. Do I need to make any other adjustments so that I can use ER without a problem?

Due to the incomplete implementation of Shibboleth on the part of some resource providers, it is not possible to use so-called multiple roles (affiliations), e.g. in the case of simultaneous studies at several faculties or employment in parallel with studies. Therefore, the user must select their main role, which will be sent to the resource provider. The settings can be changed at any time, and it becomes active after re-login to the resource. You make the adjustments on the CAS CU server.
