[keycloak-user] Refresh token error

[Michael Gerber]

Hi 

A tester in our team had the following error:

2015-12-09 15:46:39,702 WARN  [org.keycloak.events] (default task-94) type=REFRESH_TOKEN_ERROR, realmId=6b201710-e4df-4c80-9b03-852d97c63eb7, clientId=web, userId=1, ipAddress=172.25.104.2, error=invalid_token, grant_type=refresh_token, refresh_token_type=Refresh, refresh_token_id=153e0143-b0f1-4714-821a-9bb50fce301f, client_auth_method=client-secret
2015-12-09 15:46:39,702 ERROR [org.keycloak.adapters.RefreshableKeycloakSecurityContext] (default task-92) Refresh token failure status: 400 {"error_description":"Session not active","error":"invalid_grant"}

I can't reproduce it, do you have any idea what the cause could be?
