  • Publication number: 20050257072
    Abstract: Implementations are described and claimed herein to enable credential roaming among a plurality of different computing devices. An exemplary system may include an event handler to receive event notifications such as, e.g., a client logon. The event handler may invoke a management service in response to receiving an event notification. The management service may include a synchronizing module to synchronize a user's credentials with a remote directory service, such as, e.g., Active Directory, so that the user's credentials are available from any of a number of different computing devices.
