The wireless controller acts only as a POP3 client to authenticate a user by contacting an external POP3 server. This authentication option is available for IPsec, PPTP/L2TP Server and Captive Portal users. Note that POP3 for PPTP / L2TP servers is supported only with PAP and not with CHAP / MSCHAP / MSCHAPv2 encryption. To configure POP3 Server: 1.
