You have R5 configured to authenticate R4 via CHAP (ppp authentication
chap) but you don't have R4's username and password in the global
configuration. If you want R5 to only act as a client in the
authentication process just remove the "ppp authentication chap" command
from under its interface.

Guys,
This one is starting to annoy me..we'll bypass the broadcast storm issue
caused by the vlan map and jump to the HDLC portion: Why is this
failing.?
On r4 I have the following:
username Rack1R5 password 0 C1SC0?2000
!
interface Serial0/0
ip address 187.1.45.4 255.255.255.0
encapsulation ppp
no fair-queue
ppp authentication chap
end
On r5 I have
interface Serial0/0
ip address 187.1.45.5 255.255.255.0
encapsulation ppp
no fair-queue
ppp authentication chap
ppp chap password 0 C1SC0?2000
a little debug
