Can´t access keycloak due to wrong client password

I need a Java Keycloak(2.3) connection to return tokens, however I've ran into problems much earlier. When POST-requesting my Keycloak instance in Postman I get following errors in the particular console.

This is the example from Keycloak my code is based on.

Keycloak:

17:54:47,586 WARN  [org.keycloak.events] (default task-25) type=LOGIN_ERROR, realmId=master, clientId=admin-cli, userId=null, ipAddress=127.0.0.1, error=invalid_client_credentials, grant_type=password

Wildfly:

17:55:14,310 ERROR [stderr] (default task-48) javax.ws.rs.BadRequestException: HTTP 400 Bad Request

Java:

Keycloak keycloak = Keycloak.getInstance(
           KEYCLOAK_TOKEN_RESOURCE_URI,
           REALM,
           KEYCLOAK_USERNAME,
           KEYCLOAK_PASSWORD,
            KEYCLOAK_CLIENT);
    RealmRepresentation realm = keycloak.realm(REALM).toRepresentation();
Solution

  • I was able to fix the issue by changing my java code to the following 

    Keycloak keycloak = KeycloakBuilder.builder()
.serverUrl(KEYCLOAK_TOKEN_RESOURCE_URI)
.realm(REALM)
.username(KEYCLOAK_USERNAME)
.password(KEYCLOAK_PASSWORD)
.clientId(KEYCLOAK_CLIENT)
.clientSecret(CLIENT_SECRET)
.build();
