How do you enable BASIC authentication using Tomcat?

[Question continues: I'm able to get the dialog box requesting the username and password to pop up, however, even though I insert one of the usernames and passwords from the tomcat-users.xml file, I always get an "Authorization failed. Retry?" dialog.]

Make sure that the user has been designated a role in the tomcat-users.xml that matches the role(s) defined in the auth-constraint section of the web.xml:

web.xml:
<auth-constraint>
<role-name>role1</role-name>
</auth-constraint>


tomcat-users.xml:
<tomcat-users>
<user name="test" password="tomcat" roles="role1" />
</tomcat-users>


Does this help?
