ABSTRACT:
An apparatus and method for authenticating users on a data processing system is implemented. The present invention provides for aggregating authenticated identities and related authorization information. A security context created in response to a first user logon is saved in response to a second logon. A composite or aggregate security context is created based on the identity passed in the second logon. Access may then be granted (or denied) based on the current, aggregated security context. Upon logout of the user based on the second identity, the aggregate security context is destroyed, and the security context reverts to the context previously saved.
