No you only get the different logon screen after you go to that album and click on the lock icon within the album thumbnail picture. If you click the lock icon within the admin program to set the password for that album you get the standard fields to complete. Username, password, check box to see password, password hint, and etc.
You cannot use admin username and password from the screen that you get when clicking on the thumbnail of the album you want to access.
I will look at the logs.
