[keycloak-dev] OAuth2 with SAML Authentication

Hi folks I am working with some legacy systems that rely on an identity server based on SAML tokens. Therefore, I do not have the excellent features provided by the OAuth2, OpenID, and UMA specifications on these systems. I am looking for some documents to help me activate Keycloak as an identity server that works with OAuth2, but using SAML tokens for authentication. It would help a lot if such configurations were possible. Please, if anyone knows documents to help me, let me know. Kind regards, Mauricio.
