46 This command creates a new Active Directory group. The groupname specified on the command is a unique sAMAccountName.
48 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.
50 Groups may also be used to establish email distribution lists, using --group-type=Distribution.
52 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.
54 The group location (OU), type (security or distribution) and scope may all be specified on the samba-tool command when the group is created.
56 The command may be run from the root userid or another authorized userid. The
57 -H or --URL= option can be used to execute the command on a remote server.
60 samba-tool group add Group1 -H ldap://samba.samdom.example.com --description='Simple group'
62 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.
65 sudo samba-tool group add Group2 --group-type=Distribution
67 Example2 adds a new distribution group to the local server. The command is run under root using the sudo command.

115 The command deletes an existing AD group from the Active Directory domain. The groupname specified on the command is the sAMAccountName.
117 Deleting a group is a permanent operation. When a group is deleted, all permissions and rights that users in the group had inherited from the group account are deleted as well.
119 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.

166 Example1 shows how to add two groups, Group1 and Group2 and one user account, User1, to the existing AD group named supergroup. The command will be run on a remote server specified with the -H. The -U parameter is used to pass the userid and password of a user authorized to issue the command on the remote server.
