I can't find any direct mechanism either, if you don't want to use Tomcat 
internal classes.  Here's a rather ugly method, but it might work.  The web.xml 
for the webapp is accessible as a String via the JMX path:

Catalina:WebModule://[host]/[appName]:none:none:Attributes:deploymentDescriptor

Once retrieved, you could parse that for the <login-config> element.  (You 
could also just read in the web.xml file, if running from an expanded war file.)

It does seem odd that there's not a standard API to retrieve the <login-config> 
values, but I suppose that's because it's intended to be used only by 
container-managed authentication.

Note that if you leave out the <realm-name> element, it defaults to 
[host]:[port], which is easily retrievable from the Request object via 
getServerName() and getServerPort().
