• CHAP. RADIUS-Challenge Handshake Authentication Protocol (CHAP).
• MSCHAP. RADIUS-Microsoft CHAP (MSCHAP).
• MSCHAPv2. RADIUS-Microsoft CHAP version 2 (MSCHAPv2).

domain that supports the authentication method (see Configure Domains on page 388) and have added the
L2TP users to the domain (see Configure User Accounts on page 401).
