+# Provisioning of Samba. Samba is able to serve as an Active Directory (AD) domain controller (DC).
+# The entire process of setting up a Samba domain controller consists of 5 steps which are relatively straight forward. These steps are as follows:
+# 1. Installation of Samba and associated packages
+# 2. Deletion of pre-configured Samba and Kerberos placeholder configuration files
+# 3. Provisioning of Samba using the automatic provisioning tool
+# 4. Editing of the smb.conf as needed (enabling of Group Policy and/or other features as needed) see Group Policy for more information
+# 5. Any environmental configuration based on Unix/Linux Distribution
