libpam-pwdfile for Debian
-------------------------

This module allows one to authenticate users via an arbitrary password file.
The file follows the same format as /etc/passwd and /etc/shadow, although only
the first two fields are required.  In other words, each entry should start at
the beginning of a line and use the following format:

   [username]:[password-hash]


The following command provides a quick way to generate an appropriate hash,
which may then be copied into your password file.

   perl -e '$salt=q($1$).int(rand(1e8)); print "password: "; chomp($passwd=<STDIN>); print crypt($passwd,$salt),"\n"'


Here's an example of a working configuration... specifically, this is copied
from my /etc/pam.d/dovecot file.

   auth required pam_pwdfile.so pwdfile=/etc/dovecot/dovecot.passwd
   @include common-account
   @include common-session
