[keycloak-user] Is bearer token auth supported in commonly used REST client libraries?

Hi, is bearer token auth method supported in commonly used REST client libraries (eg. RESTEasy and HttpClient in java)? I tried to google around this, but no success. I was not able to find anything useful (except stuff implemented inside of Keycloak Admin Client). You know, http basic auth and ssl client cert auth is commonly available and (relatively) easy to use, so it is widely used. I believe good, easy to use, support of bearer token auth in client libraries is crucial to drive adoption of this technology, including OpenID Connect protocol, which then can drive use of Keycloak itself. By "good, easy to use, support" I mean things like automatic obtaining of access token based on the config (using OIDC "Client Credentials Grant" and "Direct Access Grants"), its automatic renewal, and automatic use of this token in REST calls performed by the client library, without any complicated coding. Any references to existing libraries? Any plans in Keycloak project itself? Vlastimil -- Vlastimil Elias Principal Software Engineer, Middleware Engineering Services Red Hat
