Authlogic x509 login

Authlogic x509 is an extension of the Authlogic library to add x509 support.

This plugin requires authlogic model based ruby authentication solution (github.com/binarylogic/authlogic). It also requires that the web server (i.e. Apache) will provide (controller.request.env) the x509 login information in the following variables:

SSL_CLIENT_S_DN (Subject DN)
SSL_CLIENT_I_DN (Issuer DN)

OR

REDIRECT_SSL_CLIENT_S_DN (Subject DN)
REDIRECT_SSL_CLIENT_I_DN (Issuer DN)

OR

HTTP_REDIRECT_SSL_CLIENT_S_DN (Subject DN)
HTTP_REDIRECT_SSL_CLIENT_I_DN (Issuer DN)

$ script/plugin install git://github.com/auth-scc/authlogic_x509.git

Add in your User class something like this:

class User < ActiveRecord::Base

  ...
  def self.find_by_x509_login(x509_subject_dn, x509_issuer_dn)
    X509Login.where(:subject_dn => x509_subject_dn, :issuer_dn => x509_issuer_dn).first && X509Login.where(:subject_dn => x509_subject_dn, :issuer_dn => x509_issuer_dn).first.user
  end

  def self.map_x509_login(x509_subject_dn, x509_issuer_dn)
    dn = X509Login.where(:subject_dn => x509_subject_dn, :issuer_dn => x509_issuer_dn).first || X509Login.new(:subject_dn => x509_subject_dn, :issuer_dn => x509_issuer_dn)
    dn.owner = self
    dn.save
  end
  ...

end
