One observation from keycloak log is as below:

2016-01-16 18:12:33,067 WARN  [org.keycloak.events] (default task-30) type=IDENTITY_PROVIDER_LOGIN_ERROR, realmId=UnileverHR, clientId=null, userId=null, ipAddress=180.107.103.49, error=identityProviderAuthenticationFailedMessage

In this case, we use the same account to lgoin from different  clients  at the same time.  That is ,we may use two machines's browser to try to login into the same IDP account.   

I am not sure this is a legal case or not . 

Thanks a lot
