Global roles with EUS not working for me

Prenner-Oracle

I have setup EUS, added enterprise users and enterprise roles. I have a database that I connected to EUS. I can successfully log in to that database using an enterprise user now. However: I have created a global role in that database, assigned it to an enterprise role and assigned this enterprise role to an enterprise user. When I log in with that user, the rights to that global role are simply not been granted to my user. When I select * from session_roles, I do not find the global role in the list. Any hints for me, where to look for?
