[keycloak-user] R: Need to log in to all realms with unique admin users

[Mattia Bello]

Dmitry, 
           the solution is acceptable. 

However, the documentation does not explain how to configure each non-master realm to do broker with master realm. 

Please, could you support me in the steps to be taken: 

1. Which identity provider should i choose? openID Connect or Keycloak OpenID Connect? 
2. How do I configure it? 
3. Where do I get information? (Authorization URL, token URL, ..)

Thank you.

Mattia,

Thanks for your explanation, the problem is clear now.

I think you can solve it with the help of identity brokering [1]. For each non-master realm, you will have to configure brokering to master. After that, a badge will appear on the login screen, and after clicking it your users will be able to authenticate with their master realm credentials.

If you're ok with this additional step, this could be an easy solution.
