AEM 6550 - Log AEM Form Login User (j_username) Password (j_password) doing j_security_check Authentication by Sreekanth Choudry Nalabotu

Abstract

If you are unsure the user authentication information like j_username, j_password are passed to /libs/granite/core/content/login.html/j_security_check or being stripped off from the request by intermediate proxies before reaching AEM, you can use the following code to log them...

Solution

Add the following custom authentication handler in a separate bundle (independent of your project) or install this package with the auth handler and log configuration logging to http://localhost:4502/system/console/slinglog/tailer.txt?tail=10000&grep=*&name=%2Flogs%2Feaem-jsecurity.log
