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

As an alternative to Amazon Directory Service for Microsoft Active Directory ([Amazon Managed Microsoft AD](directory_microsoft_ad.md)), AD Connector is an Active Directory proxy for Amazon 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 Amazon applications and services:
+ Amazon Chime - For detailed instructions, see [Connect to your Active Directory](https://docs.amazonaws.cn/chime/latest/ag/active_directory.html).
+ Amazon Connect - For more information, see [How Amazon Connect works](https://docs.amazonaws.cn/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).
+ Amazon Web Services Management Console – You can use AD Connector to authenticate Amazon Web Services Management Console users with their Active Directory credentials without setting up SAML infrastructure. For more information, see [Enabling Amazon Web Services Management Console access with Amazon Managed Microsoft AD credentials](ms_ad_management_console_access.md).
+ Quick - For more information, see [Managing user accounts in Quick Enterprise Edition](https://docs.amazonaws.cn/quicksight/latest/user/managing-users-enterprise.html).
+ Amazon IAM Identity Center - For detailed instructions, see [Connect IAM Identity Center to an on-premises Active Directory](https://docs.amazonaws.cn/singlesignon/latest/userguide/connectawsad.html).
