PrivacyIDEA Access-Challange

totp
#1

Hi,
We’ve setup PrivacyIDEA in our environment using ubuntu packages. It works quite well with a policy requiring user to provide password followed by the TOKEN code through FreeRadius so PAP + TOTP scenario. This works great.

Now we are currently setting up OpenConnect server (ocserv) which supports access-challenge type of authentication in clients out of the box (unlike eg. OpenVPN).
So the way we want to have it done is:
User authenticates using his AD username and normal password then is challenged through Radius’ access-challenge for the TOTP token. This challenge comes up as a 2nd pop-up for password but is titled appropriately.

Our policy currently is:
authentication { "challenge_response": "hotp totp", "otppin": "userstore" }

Radius config:

authorize {

if ( NAS-IP-Address == “x.x.x.x” ) {
update control {
Auth-Type := Perl
}
}

This seems to be working but unfortunately only partially.
The user is prompted for username and password when that is sent another popup (access-challenge) is issued for the TOTP token (please enter otp: ). When just the token number is provided Radius returns “wrong otp pin” because that’s what it gets from PrivacyIDEA. The user can only authenticate when he/she provides the password in a form of “AD password + TOTP token”.
The interesting bit is that we are sure that PrivacyIDEA does validate the 1st credentials (AD user + AD password) correctly when they are sent in the first request because it behaves differently when you provide incorrect password. When that’s the case it will simply say “wrong otp pin” rather than: "please enter otp: ".

So the question is:
Is it possible to construct the policy in a way that:

  1. Radius client sends Username + password
  2. Radius server, through the perl module authenticates the user against PrivacyIDEA
  3. PrivacyIDEA issues access-challenge for OTP Token
  4. User gets prompted for the Token and supplies JUST the token code
  5. This code is sent to Radius server, which then passes it to PrivacyIDEA which then checks it against stored user token and if all OK sends Access-Accept.

?

Here are the relevant RADIUS logs from when it doesn’t quite work:

Hi,

welcome to privacyIDEA.

Yes, this should work depending on the transaction_id.
See:

And obviouly this works according to your logs:

Kind regards

Yeah but for some reason it gets rejected unless I specify the actual user password + OTP Token code:

I’ll try enabling debugging in PrivacyIDEA and seeing if it shows anything more. Somehow I forgot that there was this option.

It looks as if in the ACCESS-REQUEST, that follows the ACCESS-CHALLENGE for some reason the transaction_id/state is missing.

The RADIUS client (Open AnyConnect) should handle this.

Hi,
Yeah I can see that.
I had a look in the OpenConnect source and it doesn’t support the State attribute.
Thanks for your help @cornelinux.
