4 Tap Additional Settings to assign an inner TLS authentication and set
options for server certificate validation and trust (page 204).
Additional Settings
1 Check Validate Server Certificate to verify the identity of the authenti-
cation server based on its certificate when using TLS.
2 Enter the Common Names of trusted servers. Note that if these fields are
left blank, the server certificate trust validation is not performed or required.
3 Click ok to return to the Security page.
TTLS (EAP-Tunneled TLS)
This protocol provides authentication like EAP-TLS (see page 202) but
does not require certificates for every user. Instead, authentication servers
are issued certificates. User authentication is done using a password or other
credentials that are transported in a securely encrypted “tunnel” established
using server certificates.
EAP-TTLS works by creating a secure, encrypted tunnel through which
you present your credentials to the authentication server. Thus, inside EAP-
TTLS there is another inner authentication protocol that you must configure
via Additional Settings.
Use “TTLS” to configure the use of EAP-TTLS as an authentication proto-
col, and select “Open,” “WPA,” or “Network EAP” as an association mode.
