[keycloak-dev] OIDC Discovery-enabled IdentityProvider

[Tomas Kyjovsky]

Please disregard my previous message.

Looking at the docs [1] and the Admin Console UI this should be already possible with the OIDC identity provider.
When creating a OIDC identity provider in the Admin Console there is an option at the bottom of the page to import OIDC configuration metadata from URL.

Does this cover your use case?

Tomas
