DISCONNECTED CREDENTIAL VALIDATION USING PRE-FETCHED SERVICE TICKETS

One or more user service tickets are obtained (i.e. pre-fetched) from an authentication server and stored in a ticket cache. The user service tickets facilitate a login device communicating with one or more users or group members associated with the login device. Login credentials for the users or group members may be subsequently authenticated against the user service tickets within the ticket cache thereby eliminating the need for immediate access to the authentication server or a previous login session by the users or group members. The user service tickets within the ticket cache may be refreshed as needed. In one embodiment, the user service tickets are refreshed daily and also in response to login attempts if the authentication service is readily accessible.
