Retry Login Page (retry_login.html).Figure 17. Retry Login Page

The retry_login.html file is the web page displayed to a client that has entered an invalid username and/or password, and is given another opportunity to log in.

The WAUTHRETRIESLEFTGET ESI displays the number of login retries that remain for a client that entered invalid login credentials. You can configure the number of times that a client can enter their user name and password before authentication fails with the aaa port-accessweb-basedmax-retriescommands when you enable Web Authentication. This ESI should not be modified.
