It is not possible to check a password against the shadow file without
having root privileges. Neither with nor without PAM.

Whyt you can do is install (or write yourself) a small program that
checks the password for you. That program must run as root (be installed
with suid root), but your daemon does not need to. The daemon calls the
external program to do the password check. http://unixpapa.com/pwauth
should work for your purposes.
