EctoLdap

Ecto Adapter for LDAP

Installation

From Hex, the package can be installed as follows:

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

   def deps do [{:ecto_ldap, "~> 0.3"}] end

2. Ensure ecto_ldap is started before your application:

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

3. Specify Ecto.Ldap.Adapter as the adapter for your application's Repo:

   config :my_app, MyApp.Repo, adapter: Ecto.Ldap.Adapter, hostname: "ldap.example.com", base: "dc=example,dc=com", port: 636, ssl: true, user_dn: "uid=sample_user,ou=users,dc=example,dc=com", password: "password", pool_size: 1

Usage

Use the ecto_ldap adapter, just as you would any other Ecto backend.

Example Schema

    defmodule User do
      use Ecto.Schema
      import Ecto.Changeset

      @primary_key {:dn, :string, autogenerate: false}
      schema "users" do
        field :objectClass, {:array, :string}
        field :loginShell, :string
        field :mail, :string
        field :mobile, :string
        field :skills, {:array, :string}
        field :sn, :string
        field :st, :string
        field :startDate, Ecto.DateTime
        field :uid, :string
        field :jpegPhoto, :binary
      end

      def changeset(model, params \\ :empty) do
        model
        |> cast(params, ~w(dn), ~w(objectClass loginShell mail mobile skills sn uid))
        |> unique_constraint(:dn)
      end

    end

Example Queries

    Repo.get User, "uid=jeff.weiss,ou=users,dc=example,dc=com"

    Repo.get_by User, uid: "jeff.weiss"

    Repo.all User, st: "OR"

    Ecto.Query.from(u in User, where: like(u.mail, "%@example.com"))

    Ecto.Query.from(u in User, where: "inetOrgPerson" in u.objectClass and not is_nil(u.jpegPhoto), select: u.uid)
