[yannicschroeer]

As for your question regarding Keycloak v17, there are no known issues with v17 yet. We didn't fully test it yet though.

Is anyone working on this already? Maybe @JonasScholl ?

Hi @DaGuich, I started working on it but I think I didn't have the time to finish it because it wasn't straight forward and it fell under the table 😅 We're always welcome for contributiond since we don't have much time to work on this project, so feel free to assign this to you if you want to work on it 😄 Otherwise I'll put it on top of my priority list, but I can't give an estimate on how long it will take...

After I've played around a little bit I am not so sure what to change here. As far as I can tell all functionality is working if you strip /auth from the end of the server URL.
