It sounds like you want pppd to use PAM to look up users. It's very
unusual these days for apps to directly access /etc/passwd or
/etc/shadow (what if you need NIS or LDAP auth later?). 

On my machine (RH FC1):

[root at albert root]# ldd /usr/sbin/pppd
        libpam.so.0 => /lib/libpam.so.0 (0x004ab000)
        libdl.so.2 => /lib/libdl.so.2 (0x0088d000)
        libutil.so.1 => /lib/libutil.so.1 (0x00d04000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0x00101000)
        libc.so.6 => /lib/tls/libc.so.6 (0x0072e000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x001fd000)

PPPd is built against PAM, so it should be possible. See "man pppd" for
details on settings. You'll want /etc/ppp/options and /etc/ppp/peers/*
for configuration.
