[keycloak-user] Programatic username/password access with KeyCloak using external IDP brokering

Hello, We're using Identity Brokering feature and we use external IDP. So, user logs in into external IDP UI, then KeyCloak broker client receives JWT token from external IDP and KeyCloak provides JWT with which we access our resources. We've set up "Default Identitiy Provider" feature, so external IDP login screen is displayed to the user on login. That means that users and their passwords are stored on external IDP. The problem occurs when we need to log in using "Direct Access Grant" (Resource Owner Password grant) programatically in our tests. As password is not stored on KeyCloak, we always get 401 Unauthorized error from KeyCloak on login. When I tried to change user password it started to work, so the problem is that user password is not provisioned on KeyCloak and using "Direct Access Grant" KeyCloak doesn't invoke external IDP. Is there any way it can be fixed? For example to call identity broker on "Direct Access Grant", so that KeyCloak provides us it's valid token? Regards, Yuriy
