I'm not sure I'm clear on your question. Are you saying you're trying to use a web browser to access the admin console web application and don't know the correct user name and password?
By default, the admin console (
http://localhost:8080/admin-console) uses the UsersRolesLoginModule, which gets the user names, passwords and role assignments from property files. The default login and password should be admin/admin.
If I'm not understanding your question, please excuse my response.
