In spite of my (somewhat) recent work on the CredentialHandlers, I

login to my applications.

Is there any opportunity to obtain the user's IP address during login?
IIRC, the JASPIC scheme does allow this kind of information, but I'm
not sure if Tomcat actually supplies it. JASPIC is a rather
complicated solution when I am in fact authenticating against a simple
relational database.

What might be other ways to obtain the user's IP address during

If you run Tomcat only you may use request.getRemoteAddr() in the logic
and build IP based access management around this.

If you run Apache in front of Tomcat you may need to fiddle with
X-Forwarded-For header.


+1, I was just going to mention the same.
In case of any front-end proxy, getRemoteAddr() would probably give the IP of 
the proxy.
And to make matters a little bit more complicated, see this article :
This is perl, not Java, but it provides some additional information which might be useful (about nginx and HTTPS e.g.)
