Using Keycloak as IDP frontend, with Radisys Media Server behind

Dear All,

I’m trying to configure Keycloak as a security IDP frontend to login to a Radisys Media Server. The only possible way is to use POST binding, as the Media Server does not handle redirection by itself.

For login, the KEycloak should send a SAML artifact, where the username and the SAML responder is encoded. This is what then the browser send to the Media Server, which then can query Keycloak.

I could get to the point in configuration, that the client is created, I get the login page, enter my credentials and the redirection is happening - but the Media Server GUI is not displayed. I think the SAML Artifact is not created properly.

Can you please help me - how to configure the URI and the username in Keycloak, so they will be sent in the SAML Artifact as the response for the user? And also, what should I configure as the redirection target so the Artifact is taken?

Sorry for my basic questions, I’m quite a beginner in this topic,…

Thanks, regards
Csaba
