OpenVPN + Radius mOTP question

  • Hello.

    I'm having trouble with freeradius2. I have OpenVPN working perfectly with authentication being used on the local database. I am aware this is not very secure and so I want to set up mOTP.

    Running pfSense 2.0.2

    In short, I followed these steps:

    I installed freeradius2 and set up NAS/Client with the IP being the local IP gateway. 10.X.X.1

    I set up a user with 'Enable one-time-password for this user', inputted the init-secret and PIN.

    Under the settings tab, 'Enabled mobile-one-time-password'.

    Under the interface tab, I put in '*' and port 1812.

    When I typed in the plugin command into the openVPN box under 'OpenVPN' > 'Server' (the page where info is inputted to create/server remote users… i.e. tunnel IP, local IP etc.) on the bottom of the page and clicked 'save', it says in the OpenVPN Logs:

    PLUGIN_INIT: could not load plugin shared object plugin /usr/lib64/openvpn/plugins/ Cannot open "/usr/lib64/openvpn/plugins/": Invalid arguement (errno=22)

    I believe this is the reason why I keep getting the 'Failed to authenticate' in the OpenVPN logs on the client when I try the mOTP.

    I made sure I was inputting the commands correctly in the shell where it told me to.

    I'm lost as to what to do.

    If someone could help me with this, I would be most appreciative.
