Abstract
Logon certificates are provided to support disconnected operation within the distributed system. Each logon certificate is a secure package holding credentials information sufficient to establish the identity and rights and privileges for a user/machine in a domain that is not their home domain. When a user/machine attempts to connect to the system at a domain other than the home domain of the user/machine, the user/machine presents a logon certificate that evidences his credentials. The domain where the user/machine attempts to connect to the system, decrypts and unseals the secure package as required to obtain the credentials information contained therein. If the user/machine has sufficient credentials, the user/machine is permitted to connect to the system. If the user/machine lacks sufficient credentials, the user/machine is not permitted to connect to the system.
