SecurID authentication in a Linux C++ application

Question

Can anyone recommend how to implement SecurID authentication in Linux C++ based application? I I was thinking of the following options:

1. An apache module for SecurID (we're using Apache on the front-end)
2. PAM
3. Some combination of SecurID through Radius that I've heard about but don't understand

Answer 1

Using something like ace-radius together with a RADIUS server seems to me like the easiest solution.

If I recall right RSA provides a RADIUS server in the ACE/SecurID distribution, so this should be easy to setup.
