I use the same set-up but with the difference that I use chap for
authorisation.

In my peers file the user is not defined

In my chap-secrets I use the hostname of the laptop and instead of * I use
the hostname of the server

In my case:
/AutoPPP/ -     a_ppp   /usr/sbin/pppd auth

A comment I found in my pap-secrets file:
# If you add "auth login -chap +pap" to /etc/mgetty+sendfax/login.config,
# all users in /etc/passwd can use their password for pap-authentication.
#
# Every regular user can use PPP and has to use passwords from /etc/passwd
#*      hostname        ""

This suggests to me, that if you use those options the file pap-secrets is
not checked but /etc/password

To use the pap-secrets file I think you will have to use the option:
/AutoPPP/ -    a_ppp   /usr/sbin/pppd require-pap
