The **AD/LDAP Connector** (1), is a bridge between your **Active Directory/LDAP** (2) and the **Auth0 Service** (3). This bridge is necessary because AD/LDAP is typically restricted to your internal network, and Auth0 is a cloud service running in a completely different context. Overview Diagram of AD/LDAP Connector For [high availability and load balancing](/docs/authenticate/identity-providers/enterprise-identity-providers/active-directory-ldap/ad-ldap-connector/ad-ldap-high-availability), you can install multiple instances of the connector. All connections are outbound from the connector to the Auth0 Server, so changes to your firewall are generally unnecessary. ## Prerequisites Before beginning: * [Register your Application with Auth0](/docs/get-started/auth0-overview/create-applications). * Select an appropriate **Application Type**. * Add an **Allowed Callback URL** of `{https://yourApp/callback}`. * Make sure your Application's [**Grant Types**](/docs/get-started/applications/update-grant-types) include the appropriate flows. ## Steps To connect your application to Active Directory/LDAP, you must: 1. [Create an enterprise connection in Auth0](#create-an-enterprise-connection-in-auth0) and download the installer 2. [Install the connector on your network](#install-the-connector-on-your-network) 3. [Enable the enterprise connection for your Auth0 Application](#enable-the-enterprise-connection-for-your-auth0-application) 4. [Test the connection](#test-the-connection) ## Create an enterprise connection in Auth0 1. Navigate to [Auth0 Dashboard > Authentication > Enterprise](https://manage.auth0.com/#/connections/enterprise), locate **Active Directory / LDAP**, and select its `+`. Dashboard - Connections - Enterprise 2. Enter details for your connection, and select **Create**: | Field | Description | | ---------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Connection name** | Logical identifier for your connection; it must be unique for your tenant. Once set, this name can't be changed. | | **Display name** (optional) | Text used to customize the login button for Universal Login. When set, the Universal Login login button reads: "Continue with \{Display name}". | | **Logo URL** (optional) | URL of image used to customize the login button for Universal Login. When set, the Universal Login login button displays the image as a 20px by 20px square. | | **IdP Domains** (optional) | Comma-separated list of valid email domains that will be allowed to log in using this connection. Only needed if using the Lock login widget. | | **Disable cache** | When enabled, disables caching. | | **Use client SSL certificate authentication** | When enabled, uses client SSL certificate authentication. | | **Use Windows Integrated Auth (Kerberos)** | When enabled, you will be asked to enter a range of IP addresses. When users log in through these IP addresses, Kerberos will be used; otherwise, AD/LDAP username/password will be requested. Typically, the IP range entered represent intranet addresses. | | **Sync user profile attributes at each login** | When enabled, Auth0 automatically syncs user profile data with each user login, thereby ensuring that changes made in the connection source are automatically updated in Auth0. | Enter AD / LDAP Connection Details 3\. Download the provided installer and make note of the provided **Provisioning Ticket URL**. We ship different versions of the connector to install on Windows or Linux platforms. ## Install the connector on your network Set up the [AD/LDAP Connector](/docs/authenticate/identity-providers/enterprise-identity-providers/active-directory-ldap/ad-ldap-connector) by following the instructions for your platform: * [Install the AD/LDAP Connector on Windows](/docs/authenticate/identity-providers/enterprise-identity-providers/active-directory-ldap/ad-ldap-connector/install-configure-ad-ldap-connector) * [Install the AD/LDAP Connector on Non-Microsoft Platforms](/docs/authenticate/identity-providers/enterprise-identity-providers/active-directory-ldap/ad-ldap-connector/install-configure-ad-ldap-connector) ## Enable the enterprise connection for your Auth0 application To use your new AD connection, you must first [enable the connection](/docs/authenticate/identity-providers/enterprise-identity-providers/enable-enterprise-connections) for your Auth0 Applications. ## Test the connection Now you're ready to [test your connection](/docs/authenticate/identity-providers/enterprise-identity-providers/test-enterprise-connections). ## Next Steps * [Integrate with Auth0 using one of our libraries](/docs/libraries) * [Integrate with Auth0 using our Authentication API](https://auth0.com/docs/api/authentication) * [Read more about the authentication flow](/docs/get-started/authentication-and-authorization-flow) * [Pass additional parameters to the Identity Provider](/docs/authenticate/identity-providers/pass-parameters-to-idps) * [Re-prompt users for permissions](/docs/authenticate/identity-providers/social-identity-providers/reprompt-permissions)
