Synology Directory Server provides Windows Active Directory (AD) domain service powered by Samba. It supports commonly used Windows 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.
Note: Synology Directory Server is the updated version of Active Directory Server, not LDAP Server (formerly named Directory Server).
Before you start, make sure you have done the following tasks for your Synology NAS:
View domain status.
Manage resources in domains, including users, groups, computers, and organizational units (OU).
Set up password policy and account lockout policy in domains.
