Mender user-authentication by external Identity Management and Access Management

Hello everyone,
i did some digging in the documentation & forum to try and find some information about this, but was unable to find clarification about my question.

My question is, that it would be possible for mender to let the identity & acces to it’s mender-dashboard to an external identity management & access management service, for example Keycloak which is the one i intend to use.

i’m aware of this post where OAuth2 support is not yet implemented, but OAuth2 is more for ‘giving’ resource acces & not really for identity & acces if i’m not mistaken.
As always thanks in advance!
