Chapter 12 Configuring Web-Based Authentication
Configuring Web-Based Authentication
When configuring customized authentication proxy web pages, follow these guidelines:
• To enable the custom web pages feature, specify all four custom HTML files. If you specify fewer
than four files, the internal default HTML pages are used.
• The four custom HTML files must be present on the flash memory of the switch. The maximum size
of each HTML file is 8 KB.
• Any images on the custom pages must be on an accessible HTTP server. Configure an intercept ACL
within the admission rule.
• Any external link from a custom page requires configuration of an intercept ACL within the
admission rule.
• T o access a valid DNS server, any name resolution required for external links or images requires
configuration of an intercept ACL within the admission rule.
• If the custom web pages feature is enabled, a configured auth-proxy-banner is not used.
• If the custom web pages feature is enabled, the redirection URL for successful login feature is not
available.
• To remove the specification of a custom file, use the no form of the command.
Because the custom login page is a public web form, consider these guidelines for the page:
• The login form must accept user entries for the username and password and must show them as
uname and pwd.
• The custom login page should follow best practices for a web form, such as page timeout, hidden
password, and prevention of redundant submissions.
This example shows how to configure custom authentication proxy web pages:
Switch(config)# ip admission proxy http login page file flash:login.htm
Switch(config)# ip admission prox
y http success page file flash:success.htm
Switch(config)# ip admission prox
y http fail page file flash:fail.htm
Switch(config)# ip admission prox
y http login expired page flash flash:expired.htm
This example shows how to verify the configuration of a custom authentication proxy web pages:
Switch# show ip admission configuration
Authentication proxy webpage
Login page : flash:login.htm
Success page : flash:success.htm
Fail Page : flash:fail.htm
Login expired Page : flash:expired.htm
