OTP(e.g. OPIE or FreeAuth) - authentication on FW

  • Hello,

    I would like to use OTP authentication(like OPIE or FreeAuth) in order to be able a access (from remote workstations) different applications, e.g. a webmailer like Zimbra/ZCS (behind the FW).

    I heard that - if the application does not use PAM-calls - it's not easy to setup such an environment :-(

    Due to security reasons we would prefer to have this authentication-process done directly on the firewall
    instead of using an authentication portal like capitve.

    Is there a way to integrate OPT-authentication directly on pfSense, or are there better approaches?

    Thank you very much in advance for every feedback!
