[keycloak-user] getting keycloak token with curl from PC

[John Norris]

Just to add, the keycloak has a log message of

08:06:20,217 WARN [org.keycloak.events] (default task-1)
type=LOGIN_ERROR, realmId=master, clientId=bikes-app, userId=null,
ipAddress=192.168.0.5, error=invalid_client_credentials,
grant_type=password

Not sure why userid is null when the curl command uses "username" (which does work from the server)
