NAME

Net::Squid::Auth::Plugin::SimpleLDAP - A simple LDAP-based credentials validation plugin for Net::Squid::Auth::Engine

VERSION

version 0.1.83

SYNOPSIS

If you're a system administrator trying to use Net::Squid::Auth::Engine to validate your user's credentials using a LDAP server as a credentials repository, do as described here:

On $Config{InstallScript}/squid-auth-engine's configuration file:

plugin = SimpleLDAP
<SimpleLDAP>
  # LDAP server
  server = myldap.server.somewhere       # mandatory

  # connection options
  <NetLDAP>                              # optional section with
    port = N                             #   Net::LDAP's
    scheme = 'ldap' | 'ldaps' | 'ldapi'  #     constructor
    ...                                  #     options
  </NetLDAP>

  # bind options
  binddn = cn=joedoe                     # mandatory
  bindpw = secretpassword                # mandatory

  # search options
  basedn = ou=mydept,o=mycompany.com     # mandatory
  objclass = inetOrgPerson               # opt, default "person"
  userattr = uid                         # opt, default "cn"
  passattr = password                    # opt, default "userPassword"
</SimpleLDAP>

Unless configured otherwise, this module will assume the users in your LDAP directory belong to the object class person, as defined in section 3.12 of RFC 4519, and the user and password information will be looked for in the cn and userPassword attributes, respectively. Although you can choose to use any other pair of attributes, the userattr can be set to DN, while the passattr can not.

On your Squid HTTP Cache configuration:

auth_param basic /usr/bin/squid-auth-engine /etc/squid-auth-engine.conf

And you're ready to use this module.

If you're a developer, you might be interested in reading through the source code of this module, in order to learn about it's internals and how it works. It may give you ideas about how to implement other plugin modules for Net::Squid::Auth::Engine.

METHODS

new( $config_hash )

Constructor. Expects a hash reference with all the configuration under the section <SimpleLDAP> in the $Config{InstallScript}/squid-auth-engine as parameter. Returns a plugin instance.

initialize()

Initialization method called upon instantiation. This provides an opportunity for the plugin initialize itself, stablish database connections and ensure it have all the necessary resources to verify the credentials presented. It receives no parameters and expect no return values.

_search()

Searches the LDAP server. It expects one parameter with a search string for the username. The search string must conform with the format used in LDAP queries, as defined in section 3 of RFC 4515.

is_valid( $username, $password )

This is the credential validation interface. It expects a username and password as parameters and returns a boolean indicating if the credentials are valid (i.e., are listed in the configuration file) or not.

config( $key )

Accessor for a configuration setting given by key.
