If I were going to do this, I would probably try moving to a Windows 
200x AD domain controller, and implementing RSA SecurID on that 
machine.  I have not worked with other OTP solutions.

As far as I understand, if Samba is configured as a domain controller, 
it expects to be able to handle the authentication itself.

OTP is , in my opinion, most valuable when you are exposing resources to 
the Internet (e.g. a remote access solution, web-based corporate e-mail
