[keycloak-user] Keycloak OAuth2 bearer token without using direct access grant

Hi, How can I obtain a bearer token from keycloak without using the direct access grant ( http://keycloak.github.io/docs/userguide/keycloak-server/html/direct-acce... ). I have configured a SAML Identity Broker in Keycloak which handles the login for my realm. As a result I do not have a username/password combination to POST it to: /{keycloak-root}/realms/{realm-name}/protocol/openid-connect/token How would I obtain a bearer token in this situation? Kind regards, Ton
