# Application compatibility policy for AD Connector
<a name="ad_connector_app_compatibility"></a>

As an alternative to AWS Directory Service for Microsoft Active Directory ([AWS Managed Microsoft AD](directory_microsoft_ad.md)), AD Connector is an Active Directory proxy for AWS created applications and services only. You configure the proxy to use a specified Active Directory domain. When the application must look up a user or group in Active Directory, AD Connector proxies the request to the directory. Similarly, when a user logs in to the application, AD Connector proxies the authentication request to the directory. There are no third-party applications that work with AD Connector.

The following is a list of compatible AWS applications and services:
+ Amazon Chime - For detailed instructions, see [Connect to your Active Directory](https://docs.aws.amazon.com/chime/latest/ag/active_directory.html).
+ Amazon Connect - For more information, see [How Amazon Connect works](https://docs.aws.amazon.com/connect/latest/adminguide/what-is-amazon-connect.html#amazon-connect-fundamentals).
+ Amazon EC2 for Windows or Linux – You can use the seamless Active Directory domain join feature of Amazon EC2 Windows or Linux to join your instance to your self-managed Active Directory (on-premises). Once joined, the instance communicates directly with your Active Directory and bypasses AD Connector. For more information, see [Ways to join an Amazon EC2 instance to your Active Directory](ad_connector_join_instance.md).
+ AWS Management Console – You can use AD Connector to authenticate AWS Management Console users with their Active Directory credentials without setting up SAML infrastructure. For more information, see [Enabling AWS Management Console access with AWS Managed Microsoft AD credentials](ms_ad_management_console_access.md).
+ Quick - For more information, see [Managing user accounts in Quick Enterprise Edition](https://docs.aws.amazon.com/quicksight/latest/user/managing-users-enterprise.html).
+ AWS IAM Identity Center - For detailed instructions, see [Connect IAM Identity Center to an on-premises Active Directory](https://docs.aws.amazon.com/singlesignon/latest/userguide/connectawsad.html).
+ AWS Transfer Family - For detailed instructions, see [Working with Directory Service for Microsoft Active Directory](https://docs.aws.amazon.com/transfer/latest/userguide/directory-services-users.html).
+ AWS Client VPN - For detailed instructions, see [Client authentication and authorization](https://docs.aws.amazon.com/vpn/latest/clientvpn-admin/authentication-authorization.html).
+ WorkDocs - For detailed instructions, see [Connecting to your on-premises directory with AD Connector](https://docs.aws.amazon.com/workdocs/latest/adminguide/connect_directory_connector.html).
+ Amazon WorkMail - For detailed instructions, see [Integrate Amazon WorkMail with an existing directory (standard setup)](https://docs.aws.amazon.com/workmail/latest/adminguide/premises_directory.html).
+ WorkSpaces - For detailed instructions, see [Launch a WorkSpace using AD Connector](https://docs.aws.amazon.com/workspaces/latest/adminguide/launch-workspace-ad-connector.html). 

**Note**  
Amazon RDS is compatible with AWS Managed Microsoft AD only, and is not compatible with AD Connector. For more information, see the AWS Managed Microsoft AD section in the [Directory Service FAQs](https://aws.amazon.com/directoryservice/faqs/#microsoft-ad) page.
