Re: [FW-1] Radius authentication with OTP (One time Password) sup port



Getting the Open Source radius server to work with fw1 has never been a
problem.  Works really well.  The problem is getting the radius server to
authenticate the user via some sort of OTP authentication.  Both gnu-radius
and freeradius support PAM, and freeradius supports EAP (Extensible
Authentication Protocol), but I can't seem to get it to work properly.  For
instance, I configured gnu-radius to authenticate through PAM which pointed
to a pam_opie module. If I connect locally to the server using radauth, I
see the radius server pass back the opie challenge.  The connection still
fails because radius still wants a username and pass up front.  I could be
missing something in the users file though.  Have you successfully
implemented an Open Source radius server using OTP authentication?  Thanks
for your input.

Aaron,
Does these free radius servers support other otp schemes than opie/skey?
skey is supported natively in firewall-1. But usinf a calculator is of
course a much better solution. Can you install token certs for e.g.
activcard on one of these free servers? I know you can implement SecurID
auth in ssh/openssh, but you still need the SecurID server.

I've tested several different RADIUS servers with firewall-1 and it's
usually not to complicated getting to communicate with firewall-1. Just make
sure that you define both the internal and the licensed interface as radius
clients on the radius server.
