IIS and Tomcat security

[Insyde]

Hi

Does JK2 connector pass a security information to Tomcat, like the authenticated user? 
I coudn't find any information about this in JK2 documentation. In my project, I need 
that the IIS authenticates the users, and then, the Tomcat executes my web application 
with users and roles information.

Thanks
