I failed to log in to TDM Portal using the initial username and password. Even though we gave correct username password details, authentication is failing with an error "Invalid Username/password"
Component :TDM Portal
Go through the startup.log file from TDM portal logs. If you see an error as Illegal argument exception, authentication will fail.

Please change the ARD hostname details in application.properties file by removing special characters and then restart the portal service.
