Looks like the dialin client is not configured for any authentication (pap or chap etc). So either you remove the ppp authentication commands under the interface serial 2/0:15 or configure the client for that.

Also you need to add some commands under the interface serial2/0:15..it should look like

interface serial 2/0:15

ip unnumbered FastEthernet0/0

no ip directed-broadcast

encapsulation ppp

dialer in-band

dialer idle-timeout 3600

dialer-group 2

peer default ip address pool cisco3662-group-2

ppp authentication chap pap g1

!

Test it after that..post the debugs if it doesn't work
