Why no GenericPrincipal?

Hi,

I set up a JSP to get the user principal. But when trying to access the 
principal by
   request.getUserPrincipal(),
I'll always get a plain Principal class. I expected to get a 
GenericPrincipal class by the container's UserDatabaseRealm.

I'm using the Tomcat default configuration with the UserDatabaseRealm. I 
tried this with TC 5.0.27 on Windows 2000 and TC 5.0.28 on Debian Linux.

Any thoughts?

So I hope it's "No one knows the answer".

Mh, is this not the right list for these kind of questions?
