Are you talking about authentification, or PPP negotiation? The actual
authentification should only take a few milliseconds. The timeout value on
our NAS is 3 seconds, and I have never seen it exceeded.

Point-to-Point Protocol negotiation is another matter. This is strictly
between the client and the NAS, and has nothing to do with RadiusNT.
Windows 95/98 is not really that quick when it comes to negotiating PPP. I
story I here is that is because Windows defaults to CHAP (which doesn't
work that well), and then reverts to PAP. Generally, we find that it takes
2 to 3 seconds for PAP. If the client adds Post Dial-Up, that time can be
extended to 7 or 8 seconds. Its a saw off. PAP is faster and cleaner, but
it does not support messaging. Post Dial-Up is slower, but at least it
tells you what went wrong. We recommend the latter to our users.
