Paddle

A library simplifying LDAP usage in Elixir projects.

Documentation

Why another LDAP library?

If you want to communicate with an LDAP server in Elixir, you probably know that there are other libraries out there. However, I didn't find one that suited me:

• The :eldap library is great, but very low-level, with no high-level features.

• EctoLdap is very interesting, but I needed the add / modify / delete operations (in fact, I even wanted to do an Ecto adapter at first).

• Exldap and LDAPEx are both a translation of the LDAP :eldap in Elixir, which is nice, but are still missing some higher-level features.

Usage

Once installed and configured, it allows you to quickly authenticate users:

iex> Paddle.authenticate("myUser", "password")
:ok

Get meaningful information using Paddle.Class structs:

iex> Paddle.get %MyApp.PosixAccount{uid: "myUser"}
{:ok,
 [%MyApp.PosixAccount{cn: ["My User"], description: nil,
   gecos: ["My User,,,,"], gidNumber: ["120"],
   homeDirectory: ["/home/myuser"], host: nil, l: nil,
   loginShell: ["/bin/bash"], o: nil, ou: nil, seeAlso: nil, uid: ["myUser"],
   uidNumber: ["500"],
   userPassword: ["{SSHA}AIzygLSXlArhAMzddUriXQxf7UlkqopP"]}]}

Or get information just about anything:

iex> Paddle.get base: [ou: "People"], filter: [objectClass: "organizationalUnit"]
{:ok,
 [%{"dn" => "ou=People,dc=test,dc=com",
    "objectClass" => ["top", "organizationalUnit"], "ou" => ["People"]}]}

Add, delete, modify operations are supported. If you want to know more, just go to the documentation.

Installation

The package can be installed as:

1. Add paddle to your list of dependencies in mix.exs:

   def deps do
     [{:paddle, "~> 0.1.0"}]
   end
   

2. Ensure paddle is started before your application:

   def application do
     [applications: [:paddle]]
   end
   

3. Add your configuration in your config files:

   config :paddle, Paddle,
     host: "ldap.my-organisation.org",
     base: "dc=myorganisation,dc=org",
     ssl: true,
     port: 636
   

   For more configurations, see the Paddle module docmumentation.

Testing

If you want to test this application, you can use the linux commands described in the .travis.yml file in the before_script block to start a local test LDAP server.

Keep in mind that you may need to change the .travis/ldap/slapd.conf for your system by changing some configuration paths.

If you want to add some more data to the test server, please feel free to issue a pull request.
