Bill,
Tomcat will use my authenticator regardless of "login-config/auth- method" setting? If it is the case, how my Authenticator can figure- out what auth-method was configured (normally my authentication method will be used in-addition to what ever standard method has been used)?
        Thanks,

Andrei

I understand. My problem it twofold. In order to make an authentication
decision ...
- I need to have an access to some information from HTTP Request,
- I need to be able build HTTP Response (basically, I need to be able to
issue challenge in response to authentication request).
As I stated in my original post, I think that right place to put this
kind of functionality is authenticator. My original question was, if it is possible to register new Authenticator without re-compiling Tomcat.



Yes, it is possible. You just create your own Authenticator class (probably
extending Tomcat's AuthenticatorBase and implementing the authenticate
method).  Then you do:
   <Context ......>
       <Valve className="com.myfirm.mypackage.MyAuthenticator" .... />
        ....
   </Context>
This will cause Tomcat to use your Authenticator instead of one of it's own.

I was just commenting that I can not see how JAASRealm
(or any Realm for that matter) can help me

Specifying JAASRealm as the <Realm> gives you the opportunity to
implement your own LoginModule.  Such a LoginModule can utilize any
number of authentication mechanisms - all under your control.
