Add-ADGroupMember

Add-ADGroupMember is accessible with the help of addsadministration module. To install addsadministration on your system please refer to this link.

Synopsis
Adds one or more members to an Active Directory group.

Description
The Add-ADGroupMember cmdlet adds one or more users, groups, service accounts, or computers as new members of an Active Directory group.
The Identity parameter specifies the Active Directory group that receives the new members. You can identify a group by its distinguished name (DN), GUID, security identifier (SID) or Security Accounts Manager (SAM) account name. You can also specify group object variable, such as $, or pass a group object through the pipeline to the Identity parameter. For example, you can use the Get-ADGroup cmdlet to get a group object and then pass the object through the pipeline to the Add-ADGroupMember cmdlet.
The Members parameter specifies the new members to add to a group. You can identify a new member by its distinguished name (DN), GUID, security identifier (SID) or SAM account name. We can also specify user, computer, and group object variables, such as $. If you are specifying more than one new member, use a comma-separated list. We cannot pass user, computer, or group objects through the pipeline to this cmdlet. To add user, computer, or group objects to a group by using the pipeline, use the Add-ADPrincipalGroupMembership cmdlet.

For AD LDS environments, the Partition parameter must be specified except in the following two conditions:
-The cmdlet is run from an Active Directory provider drive.
-A default naming context or partition is defined for the AD LDS environment. To specify a default naming context for an AD LDS environment, set the msDS-defaultNamingContext property of the Active Directory directory service agent (DSA) object (nTDSDSA) for the AD LDS instance.
