Now, your Tomcat server is enabled with two-factor authentication, and the access to the web page “/sample/hello.jsp” requires two-factor authentication. 

To make a quick test, visit the /sample application in a web browser by URL:
http://acme.org/sample

Clicking the link “page protected by 2FA”, you’ll be redirected to the DualShield SSO server to be authenticated with MFA:
http://dualshield.deepnetsecurity.local/...

Once you have been successfully authenticated, you will be redirected back to your web application and granted access to the protected page,  /sample/hello.jsp
