Release Notes for Synology Directory Server

Synology Directory Server provides Active Directory (AD) domain service powered by Samba. It supports commonly used Active Directory features such as user accounts, group memberships, domain-joining Windows, Linux and Synology DSM, Kerberos-based authentication, and group policies. This makes it easier to manage computers and devices running Synology DSM, Linux, Windows, and deploy Windows applications.
