Both Tomcat 3.x and Catalina have the concept of a Realm that separates
the idea of looking up users and passwords from the idea of where they
are looked up (the implementation details are a little different, but the
concept is the same).  Both implementations default to an XML file in the
"conf" directory, but both of them let you configure something different
if you want it.  Both currently include a Realm implementation that lets
you go to a database for your authorization information.

Contributions for other sources of authentication would certainly be
