Sounds like the chat script isn't correct.

I've never done it, but from comments on the net, the chat script needs
to take everything through to the point of starting PAP negotiations.
So you should have a PPP connection "up" at the end of chat'ting.

Then you add an option to /etc/ppp/options to select PAP, and tell pppd
the shared secret to use in PAP'ing.

man pppd should tell a bit more, and maybe ask on -current.

Good luck,

Bill
