Radius question

[Jason Dixon]

I apologize if this is not the most appropriate forum for this  
question, but it seems close enough.  I need to setup a new RADIUS  
server on OpenBSD, but I'm looking for one that will allow me to run  
an external command for authentication.  Is this possible?  Do either  
of the RADIUS ports on OpenBSD (cistron, lucent) support this?

Thanks in advance,
