If you look at the KerberosLoginModule code, it wants to be modified to retrieve roles from somewhere in your system. For example a user database that says that u...@realm is "manager". Then you can say <auth-constraint> ... manager </> in web.xml rather than u...@realm. Listing individual users clearly isn't practical.
Any authenticated user will be a member of "Everyone" or "DOMAIN\Authenticated Users" or "DOMAIN\Users", etc. If you are using Active Directory on Windows, you're probably not getting what you want with Kerberos alone. To use web.xml for authorization, you want something like roles = AD groups (and local groups). Retrieving user groups by name from AD is going to yield the wrong result in any kind of real world deployment - you will have hard time getting nested groups or anything from trusted domains. If you're running on Windows and your goal is single sign-on, you may want to try http://waffle.codeplex.com. There're several options, including a login filter and a JAAS authenticator. All use SSPI to login (will do Kerberos and NTLM) and will return not just the user identity, but the user local and domain groups.

If I hard-code the u...@realm in the web.xml file, authentication is successful. However obviously what one really wants is the actual user credentials as stored in the Principals class, javax.security.auth.kerberos.KerberosPrincipal, in the web.xml for each Subject authenticating, but I'm a bit lost as to how to get that information from the class into the web.xml. Any ideas would be appreciated?
