We have a contract with username and password to protect a resource. If a user is in a specific group then we do a re-authenticate with another contract (step-up authentication).
This another contract is a radius contract with username and Tokencode. This is all working fine.

Now I want to achieve te following. On this second Radius contract I want to fill in the username automatically. Is there a way to auto populated this username in this contract?

I've read the other posts in the form of this certain topic but cannot find a solution.
