# Supported Regions and Aurora DB engines for Kerberos authentication
<a name="Concepts.Aurora_Fea_Regions_DB-eng.Feature.KerberosAuthentication"></a>

By using Kerberos authentication with Aurora, you can support external authentication of database users using Kerberos and Microsoft Active Directory. Using Kerberos and Active Directory provides the benefits of single sign-on and centralized authentication of database users. Kerberos and Active Directory are available with Amazon Directory Service for Microsoft Active Directory, a feature of Amazon Directory Service. For more information, see [Kerberos authentication](database-authentication.md#kerberos-authentication).
