Re: Pass-Through Authentication

How hard would it be to create a new pass-through authentication mechanism (something other than SASL) for OpenLDAP? Can this be done in an overlay?
The reason I ask is that I'm investigating using two-factor authentication. If I understand the marketing materials correctly, both the RSA SecureID system and the WiKID system expose a RADIUS server that clients can authenticate with. The suggested set-up seems to be:
OpenLDAP -> SASL -> pam -> RADIUS (on 3rd party token server)
SASL/OTP already supports one-time password authentication. If that doesn't
directly do what you want, I suggest you explore
OpenLDAP -> SASL -> <something>
This seems like a lot of intermediaries, and a lot of potential "breaking" points. I wonder if there isn't any way to just cut the middle man out, so to speak, and have OpenLDAP talk directly to a RADIUS server, eliminating the other layers inbetween:
OpenLDAP -> RADIUS (on 3rd party token server)
Perhaps a password scheme like:
No. We really really don't like new password schemes.
I've worked with RADIUS before, and it's not all that bad from a client implementation perspective, especially if you ignore the challenge/response part of the protocol (which most simple authentication services seem to do).
Or should I just shut up and use the first method? :)
