VPN with XP using post dial terminal authentication (RSA)

[PapaSmurf]

I'm using a security system from RSA called secureid. To support windows 98 clients the server must use post dial terminal based authenticaton. The other method available (EAP client) works fine on the same server with Windows XP VPN clients dialing in.

I don't think that Windows XP clients can use post dial authentication with VPN at all.

Can anyone else confirm/disprove this theory?

Thanks
