# Amazon Private CA Connector for Active Directory
<a name="connector-for-ad"></a>

Amazon Private CA can issue and manage certificates required by Amazon Managed Microsoft AD. Using the Amazon Private CA Connector for Active Directory (Connector for AD), you can replace on-premises enterprise or other third-party CAs with a managed private CA that you own, providing certificate enrollment to users, groups, and machines that are managed by your AD.

You can use the Connector for AD with Amazon Managed Microsoft AD to eliminate on-premises infrastructure by migrating your AD and public key infrastructure to the cloud. For customers looking to use Amazon Private CA with their on-premises AD, this feature also integrates with Amazon Managed Microsoft AD Connector.
