Application Tracking: User role integration into AppTrack logs

User identity details such as user name and user role are added to the AppTrack session create, session close, and volume update logs. This information is obtained from the Unified Access Control (UAC) connection or from the local authentication table. These fields will contain the user name and role associated with the policy match. One can enable the logging of user name and roles for security policies that provide UAC enforcement or with an entry in the local authentication table. For security policies without Userfw enforcement, the user name and the user role field in the log is displayed as N/A. The user name is displayed as unauthenticated-user and user role is displayed as N/A, if the device cannot retrieve information for that session because there is no authentication table entry for that session or because logging of this information is disabled. The user role field in the log will contain the list of all the roles performed by the user if match criteria is specific, authenticated-user, or any and the user name field in the log contains the correct user name. The user role field in the log will contain N/A if the match criteria and the user name field in the log contains unauthenticated user or unknown user.
