In this article, we will show you how to join servers or workstations running CentOS 8, RHEL, or Rocky Linux to an Active Directory domain using realmd, and how to authenticate to a Linux host using an Active Directory account. The Realmd (Realm Discovery) service makes discovering and adding Linux hosts to an AD domain much easier. Realmd uses SSSD (via Kerberos and LDAP) or Winbind to verify and authenticate Active Directory accounts.
