1.) Create a local user Account from Control Panel(user should be created on Qlik sense server system).
2.) Try to access the Qlik Sense with the newly created User Account.(you will be probably able to access the Qlik).
3.) once the Qlik is accessible login with the Admin access user and check if the user is visible in QMC userlist or not. If user is visible allocate the license and access the Qlik.
