Using OTP authentication with Freeradius 2

[Greg Woods]

I am trying to migrate from freeradius 1.1.7 to freeradius 2.0.5 and I
cannot get the OTP module to work. Basically it instantiates, but when I
specify "Auth-Type = OTP" in a users file entry, it complains that this
is not a valid value for that attribute. This worked fine under 1.1.7 .
I have been Googling, grepping the source code and reading the wiki for
a couple of days now without finding anything that directly pertains to
this problem. I don't know if I messed up compiling the code or
configuring the server. If this is documented somewhere, please forgive
me, as I have been unable to find it.

Here are the relevant snippets from the -X output; the full output is
attached:

including configuration file /usr/local/etc/raddb/modules/otp
[...]
including configuration file /usr/local/etc/raddb/otp.conf
[...]
 Module: Linked to module rlm_otp
Module: Instantiating otp
  otp {
        otpd_rp = "/var/run/otpd/socket"
        challenge_prompt = "Challenge: %s  Response: "
        challenge_length = 6
        challenge_delay = 30
        allow_sync = yes
        allow_async = no
        mschapv2_mppe = 2
        mschapv2_mppe_bits = 2
        mschap_mppe = 2
        mschap_mppe_bits = 2
  }

And then it craps out at the end with:

/usr/local/etc/raddb/users[4]: Parse error (check) for entry DEFAULT:
Unknown value otp for attribute Auth-Type
Errors reading /usr/local/etc/raddb/users

The entry that worked under 1.1.7 (and which results in the above error
under 2.0.5) is:

DEFAULT Auth-Type = OTP
        Fall-Through = No

Thanks for any pointers; I am pretty much dead in the water in my
migration at this point.
