HTTP authentication over form authentication
About this task
In some instances an application may use both types of authentication. HTTP authentication may be used generally on all pages, while Form authentication is used to protect specific administrator areas. In such cases you will probably want to run both types of test.
HTTP Authentication: This is tested as described above (see HTTP authentication)
Form Authentication: To test this you need to provide Authentication Tester with the actual username and password for the HTTP authentication. This will enable it to "get past" the HTTP authentication and test the Form authentication on these pages.
