This extension provides PAM (Pluggable Authentication Modules) integration. The library provides a stable API for applications to defer to for authentication tasks.
Users whould be aware that on systems using shadow passwords, authentication of users other than the current user will fail unless either a) the authenticating Ruby code is executed as root or, b) /sbin/unix_chkpwd is suid root (or sgid shadow).
On some distros, this is the case by default; otherwise, it may be necessary to run:
sudo chmod 2755 /sbin/unix_chkpwd
assuming /etc/shadow is set 0640 and owned by root:shadow, and /sbin/unix_chkpwd is owned by root:shadow.
In a nutshell (using the 'rpam' PAM service):
require 'rpam' if Rpam.auth("user","password") == true
puts “Authenticate Successful”
else puts "Authenticate Failure" end
Or, to use a different PAM service:
if Rpam.auth("user", "password", :service => 'my_foo') == true
This also supports compatibility with the original 'rpam':
include Rpam if authpam("user","password") == true
gem install rpam-ruby19 (might need sudo privileges)
Or, you can do it the hard way (without Rubygems):
tar xzf rpam-*.tar.gz
make install (might need sudo privileges)
