Overview of Functionality ???: Crystal Reports Server 11.5 2004

Is there a way to get Crystal Server to pull existing Users and Groups from AD so I donu2019t have to create them manually?

In a typical implementation, how much security can be handled by AD and how much must be done in Crystal server.

Must I create accounts for all users intending to view reports available in Crystal Server or can I configure Crystal Server to use AD completely for security and authentication?
