Use ppp auth chap callin with a class map on the dialer interface.
PPP Callback Server
interface bri 0
ip address 10.1.1.7 255.255.255.0
encapsulation ppp
dialer callback-secure
dialer enable-timeout 2
dialer map ip 10.1.1.8 name atlanta class dial1 81012345678901
dialer-group 1
ppp callback accept
ppp authentication chap
!
map-class dialer dial1
dialer callback-server username
PPP Callback Client
interface bri 0
ip address 10.1.1.8 255.255.255.0
encapsulation ppp
dialer map ip 10.1.1.7 name dallas 81012345678902
dialer-group 1
ppp callback request
ppp authentication chap callin
Another option would be to use ISDN caller id, since technically only
the receiving end is authenticating (by received number). From the
original question at the bottom of this thread, it says authenticate and
use chap, not necessarily authenticate by chap!

Since the requirement said to use chap authentication I don't think
using
pap would be the solution. I would imagine callin is the solution...

I know where this question came from due to taking the lab this past
Oct.
but believe me when I say this. This is not the solution (chap callin).
I
tried it myself. I think using PAP is the correct answer but if I knew
for
sure, I would be replying with a ccie number at the end of my name. But
I
don't want to go into to much detail and go against my NDA.

Just for curiosity sake, where did you see this requirement? I would be
interested in the material.
