Built-in Portal Authentication Verification
If the test-aaa command succeeds, use a real terminal to perform Portal authentication. Open the Portal authentication page and enter the user name and password for authentication. If the authentication still fails, the configuration of built-in Portal authentication may be incorrect. LDAP and AD authentication supports only PAP. Therefore, ensure that the built-in Portal authentication mode is set to PAP.
