Yes. It is possible ;)
Write a custom Realm, probably extending RealmBase. Methods such as
authenticate(username,credentials) return your custom Principal.
The custom realm has to be packaged in to commons/lib. The way we got
around classloader hell was to have an interface in common/lib which was
an(other) abstraction for user authentication. The realm looks up an
implementation of this type by JNDI. The implementation specified in the
context.xml Resource element is just a wrapper that is populated by your
webapp (again by JNDI) with the real authenticator.
It's a round the houses mechanism but keeps the real logic out of
commons/lib and in the webapp where it belongs.

If you're implementing JAAS... no. No idea about the rest. Its not supported
in Tomcat (But should be). Stick it in the session, and then you have to
override the Tomcat HttpRequestProcessor (isUserInRole()) to get your
Principal out of the session and call the validation.

Subject: Is it even possible to retrieve a custom user principal? (Was:
Tomcat user principal)
Hello,
As this has become a bit of a roadblock in implementing security, I'd
like to ask anyone out there two things:
1) Is it even possible to use a custom user princpal within a realm that
is retrievable within a servlet (via presumably the request or
otherwise) in Tomcat?
2) If the answer to #1 is yes, how is this done? Does anyone have a
working code snippet that demonstrates this?
Thanks, I'm about to head to the developer list to ask this question, as
its pretty crucial for our security implementation.

I would have expected that designation of the user class name would
have resulted in my being returned the class I specified for the
user class name from the requestion.getUserPrincpal() method, but it
doesn't.
What version of Tomcat are you using? As far as I know, it works the
way you want on 5.0.28. I remember trying it with and without the
class name, and writing that comment to remind myself.
Could this be it?
http://issues.apache.org/bugzilla/show_bug.cgi?id=37044
I am using 5.0.28, and I'm not seeing the expected behavior.
Hmmm.....was there anything else that has to be done to be able to
access your own custom user principal?
