  3. Enabling the Browser to Return Kerberos Tokens.


  4. Test WNA for WLS Console.
    e.g.:
          http://server:7001/console

    Note you are authenticated without providing user credentials as expected.

  5. Test WNA for WebCenter Content.
    e.g.:
         http://server:16200/cs

    • You will get the welcome page for WebCenter Content with a Logon Link.

    • Click the Logon Link.

    • Note you are authenticated to WebCenter Content without providing user credentials.

       

  6. Test WNA for WebCenter Portal with public page access.
    This is with -oracle.webcenter.spaces.osso=true flag when starting the WC_Spaces managed server.

    28.4.3 Configuring Microsoft Clients
    28.4.3.3 Configuring WebCenter Portal

    e.g.:
          http://server:8888/webcenter

    • You will get the welcome page with a Login button.

    • Click the Login button.

    • You will see the following message:

      Sorry, you do not have access.
      If you have an account, please login first.
       
    • Click the "here" link in the "Click here to go to home" message.
      You will get back to the Welcome page with the Login button.

    • Click the Login button again.
      This time you should see the Login form.

    • Provide the Username and password and click Login.
      This time you are logged in.
      But you should not need to provide user credentials (This is the issue).

  7. Test WNA for WebCenter Portal turning off public page access.

    This is removing View access from the Public-User role.

    • This time you should see the Login form right away, this is wrong!

    • Provide the Username and password and click Login.
      You will see the following message:

      Sorry, you do not have access.
       

    • Click the "here" link in the "Click here to go to home" message.

      Now you are authenticated.
      But this is wrong, you should not need to provide user credentials.
