If you have access to Arubapedia (for Partners and Aruba employees), you could check
this page with a section on the Authentication Text and an example.
Note that the Authentication text only works on HTTP sites, as the HTML on the server is checked for the authentication text when the client retrieves it. It may be hard to find a non-HTTPS web service these days... and the user's browser may complain about an unencrypted connection. With HTTPS the AP cannot detect the HTML (as it is encrypted), so that is incompatible with Authentication Text. Don't hear this feature is used a lot, which may be because HTTP starts to slowly disappear.
