I have not tried your suggestion, but I think it will work.  The reason 
why I have not done that is because I was looking at the general case of 
other applications that may have auth constraints, not just Tomcat 
Manager.  Especially if the auth constraints are more complex than the 
ones Tomcat Manager has.  Plus, by understanding what is happening and 
why, I learn more about Tomcat.

Right now, I am experimenting with implementing my own realm; I think it 
may be possible to get the desired functionality under Tomcat that way.  
If this does not work or if it is too hard for me, I will use your 
suggestion.  But I am new to both Java and Tomcat, and so I wonder if 
there is yet another way of which I am ignorant.

Thank you for your help!
