PAP one-way authentication failing..

hi,

I connected two routers R1 and R2 via serial link to configure ppp pap uni-directional authentication but its not working. following is the config

R1:

username PAPU password cisco

interface Serial0/0
ip address 10.1.1.1 255.255.255.0
encapsulation ppp
ppp authentication pap
end

R2:

interface Serial0/0
ip address 10.1.1.2 255.255.255.0
encapsulation ppp
ppp authentication pap callin
ppp pap sent-username PAPU password 0 cisco
end

and it is showing the following msg when i run debug pap authenication on both routers

*Mar  1 01:04:32.467: Se0/0 PPP: Authorization required
*Mar  1 01:04:32.675: Se0/0 PPP: Authorization required
R1#
*Mar  1 01:04:34.671: Se0/0 PPP: Authorization required
R1#u
*Mar  1 01:04:36.619: Se0/0 PPP: Authorization required

Did i configure some thing wrong..

Remove

ppp authentication pap callin

From R2

You are making R2 an authentication server as well while per your output and requirements, R2 is just the client.

Hello Nareh,

check if AAA new model is configured on your routers

or if you like post

sh run | inc aaa

Edit:

I think Edison is on spot here

Hope to help
