+
+This command creates a new Active Directory group.  The groupname specified on the command is a unique sAMAccountName.
+
+An Active Directory group may contain user and computer accounts as well as other groups.  An administrator creates a group and adds members to that group so they can be managed as a single entity.  This helps to simplify security and system administration.
+
+Groups may also be used to establish email distribution lists, using --group-type=Distribution.
+
+Groups are located in domains in organizational units (OUs).  The group's scope is a characteristic of the group that designates the extent to which the group is applied within the domain tree or forest.
+
+The group location (OU), type (security or distribution) and scope may all be specified on the samba-tool command when the group is created.
+
+The command may be run from the root userid or another authorized userid.  The
+-H or --URL= option can be used to execute the command on a remote server.
+
+Example1:
+samba-tool group add Group1 -H ldap://samba.samdom.example.com --description='Simple group'
+
+Example1 adds a new group with the name Group1 added to the Users container on a remote LDAP server.  The -U parameter is used to pass the userid and password of a user that exists on the remote server and is authorized to issue the command on that server.  It defaults to the security type and global scope.
+
+Example2:
+sudo samba-tool group add Group2 --group-type=Distribution
+
+Example2 adds a new distribution group to the local server.  The command is run under root using the sudo command.
