Active Directory authentication with Samba 4
Samba is an open source implementation of multiple protocols that are required for interoperability with Microsoft Windows machines, including the SMB file-sharing protocol (which is where the Samba name came from). Apart from file sharing, it also implements authentication and user management – initially, it only supported Windows NT domains, but since 4.0.0, it has full support for Active Directory that’s compatible with Windows Server 2008 and also includes built-in LDAP and DNS backends, which makes small installations very simple to deploy.
Setting up the domain controller
$ sudo dnf install samba-dc
Then, you may want to remove all configuration files for Samba and the Kerberos daemon to ensure a clean state:
$ sudo rm -f /etc/samba/smb.conf $ sudo rm -f /etc/krb5.conf
Samba includes a command for automatically provisioning domain controllers...
