TTLS (EAP-Tunneled TLS)
This protocol provides authentication like EAP-TLS (see page 382) but
does not require certificates for every user. Instead, authentication servers
are issued certificates. User authentication is done using a password or oth-
er credentials that are transported in a securely encrypted “tunnel” estab-
lished 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.
