Configuring Authentication for Network Access Chapter 17 Applying AAA for Network Access Step 5 hostname(config)# auth-prompt reject invalid-credentials text To show text when a user is rejected due to an expired password, enter the following command: hostname(config)# auth-prompt reject expired-pwd text This prompt is only used if the RADIUS server uses a Windows Active Directory server for the username and password. You must configure a prompt using the expired-pwd keyword for the user to be prompted for a new password. The following example sets the authentication prompt to the string "Please enter your username and password.": hostname(config)# auth-prompt prompt Please enter your username and password After this string is added to the configuration, users see the following: Please enter your username and password User Name: Password: You can also provide separate messages to display when the FWSM accepts or rejects the authentication attempt; for example: hostname(config)# auth-prompt reject Authentication failed. Try again. hostname(config)# auth-prompt accept Authentication succeeded. To set rejection messages for invalid credentials, expired password, and for unknown rejection reasons, enter the following commands: hostname(config)# auth-prompt reject Authentication failed. Try again. hostname(config)# auth-prompt reject invalid-credentials Incorrect username or password hostname(config)# auth-prompt reject expired-pwd Your password is expired. Reset your password and try again. Enabling Secure Authentication of Web Clients The FWSM provides a method of securing HTTP authentication. Without securing HTTP authentication, usernames and passwords provided to the FWSM would be passed to the destination web server. By using the aaa authentication secure-http-client command, you enable the exchange of usernames and passwords between a web client and the FWSM with HTTPS. HTTPS encrypts the transmission, preventing the username and password from being passed to the external web server by HTTP. After enabling this feature, when a user accesses a web page requiring authentication, the FWSM displays the Authentication Proxy Login Page shown in Figure 17-1. 17-6 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM OL-20748-01
