Keycloak provider

[carlroeber98]

Hi there,

I am using an external provider keycloak and I am trying to authenticate my request to a specific path.
So for example my frontend needs to be secured. Traefik redirects to it under the path /frontend (PathPrefix(/frontend) and I have added the labels for the forward-auth according to the documentation. The redirection to the provider is working fine but then I am getting redirected to that URL_PATH (_oauth?sessionState...,redirectURL=myhost/frontend).
Which basically means my path is getting changed from /frontend to /oauth and I am not sure what to do about it ?
Where does this URL_PATH needs to redirect to ? And how do I handle step 4. Token, user and CSRF cookie is validated (this request in intercepted and is never passed to your application) ?

Also worth mentioning is that I am not using the forward-auth container as entrypoint. Can this be an issue ?
If more information about my setup is required let me know.

I would really appreciate an answer since I am not too deep into that topic.
Thanks :)
