TTLS and PEAP bypassed the certificate issue by tunneling TLS, and thus eliminating the need for a certificate on the client side.
PEAP supports only EAP-compliant authentication protocols within the tunnel structure, and is rapidly becoming the most widely
supported of the EAP methods. TTLS supports pre-EAP authentication protocols within the tunnel structure, and should be used
in those circumstances when pre-EAP interior protocols are desirable.
LEAP is a pre-EAP, Cisco-proprietary protocol, with many of the features of EAP protocols. Cisco controls the ability of other
vendors to implement this protocol, so it should be selected for use only when limited vendor choice for client, access-point, and
server products is not a concern.
