I'm not sure i understand the question but are you doing something along
these lines?

R1
user R2 pass CISCO
interface virtual-template1
  ip add 10.1.1.1 255.255.255.0
  encap ppp
  ppp authen chap
R2
user R1 pass CISCO
interface virtual-template1
  ip add 10.1.1.2 255.255.255.0
  encap ppp
  ppp authen chap

By default this will use the local user database, with or without "aaa
authen ppp default local". The minute you enable aaa authentication with
"local" authentication for PPP, and you don't have the appropriate user
accounts defined, your PPP link will not come up. You can try that out and
see.
