NAME Add-ADGroupMember
SYNOPSIS
Adds one or more members to an Active Directory group.
SYNTAX
Add-ADGroupMember [-Identity] <ADGroup> [-Members] <ADPrincipal[]> [-AuthType {Negotiate | Basic}] [-Credential
<PSCredential>] [-Partition <String>] [-PassThru] [-Server <String>] [-Confirm] [-WhatIf] [<CommonParameters>]
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 $<localGroupObject>, 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. You can also specify user, computer,
and group object variables, such as $<localUserObject>. If you are specifying more than one new member, use a
comma-separated list. You 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.
PARAMETERS
-AuthType <ADAuthType>
Specifies the authentication method to use. Possible values for this parameter include:
Negotiate or 0
Basic or 1
The default authentication method is Negotiate.
A Secure Sockets Layer (SSL) connection is required for the Basic authentication method.
The following example shows how to set this parameter to Basic.
-AuthType Basic
Required? false
Position? named
Default value Microsoft.ActiveDirectory.Management.AuthType.Negotiate
Accept pipeline input? false
Accept wildcard characters? false
-Credential <PSCredential>
Specifies the user account credentials to use to perform this task. The default credentials are the
credentials of the currently logged on user unless the cmdlet is run from an Active Directory PowerShell
provider drive. If the cmdlet is run from such a provider drive, the account associated with the drive is the
default.
To specify this parameter, you can type a user name, such as "User1" or "Domain01\\User01" or you can specify a
PSCredential object. If you specify a user name for this parameter, the cmdlet prompts for a password.
You can also create a PSCredential object by using a script or by using the Get-Credential cmdlet. You can
then set the Credential parameter to the PSCredential object The following example shows how to create
credentials.
$AdminCredentials = Get-Credential "Domain01\\User01"
The following shows how to set the Credential parameter to these credentials.
-Credential $AdminCredentials
If the acting credentials do not have directory-level permission to perform the task, Active Directory
PowerShell returns a terminating error.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Identity <ADGroup>
Specifies an Active Directory group object by providing one of the following values. The identifier in
parentheses is the LDAP display name for the attribute.
Distinguished Name
Example: CN=saradavisreports,OU=europe,CN=users,DC=corp,DC=contoso,DC=com
GUID (objectGUID)
Example: 599c3d2e-f72d-4d20-8a88-030d99495f20
Security Identifier (objectSid)
Example: S-1-5-21-3165297888-301567370-576410423-1103
Security Accounts Manager (SAM) Account Name (sAMAccountName)
Example: saradavisreports
The cmdlet searches the default naming context or partition to find the object. If two or more objects are
found, the cmdlet returns a non-terminating error.
This parameter can also get this object through the pipeline or you can set this parameter to an object
instance.
This example shows how to set the parameter to a distinguished name.
-Identity "CN=saradavisreports,OU=europe,CN=users,DC=corp,DC=contoso,DC=com"
This example shows how to set this parameter to a group object instance named "ADGroupInstance".
-Identity $ADGroupInstance
Required? true
Position? 1
Default value
Accept pipeline input? True (ByValue)
Accept wildcard characters? false
-Members <ADPrincipal[]>
Specifies a set of user, group, and computer objects in a comma-separated list to add to a group. To identify
each object, use one of the following property values. Note: The identifier in parentheses is the LDAP display
name.
Distinguished Name
Example: CN=SaraDavis,CN=Europe,CN=Users,DC=corp,DC=contoso,DC=com
GUID (objectGUID)
Example: 599c3d2e-f72d-4d20-8a88-030d99495f20

Example: S-1-5-21-3165297888-301567370-576410423-1103
SAM Account Name (sAMAccountName)
Example: saradavis
You can also provide objects to this parameter directly.
The following examples show how to specify this parameter.
This example specifies a user and group to add by specifying the distinguished name and the SAM Account Name
properties.
-Members "CN=SaraDavis,CN=employees,CN=Users,DC=contoso,DC=com", "saradavisreports"
This example specifies a user and a group object that are defined in the current Windows PowerShell session as
input for the parameter.
-Members $userObject, $groupObject
The objects specified for this parameter are processed as Microsoft.ActiveDirectory.Management.ADPrincipal
objects. Derived types, such as the following are also received by this parameter.
Microsoft.ActiveDirectory.Management.ADUser
Microsoft.ActiveDirectory.Management.ADComputer
Microsoft.ActiveDirectory.Management.ADServiceAccount
Microsoft.ActiveDirectory.Management.ADGroup
You cannot pass objects through the pipeline to this parameter.
Required? true
Position? 2
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Partition <String>
Specifies the distinguished name of an Active Directory partition. The distinguished name must be one of the
naming contexts on the current directory server. The cmdlet searches this partition to find the object defined
by the Identity parameter.
The following two examples show how to specify a value for this parameter.
-Partition "CN=Configuration,DC=EUROPE,DC=TEST,DC=CONTOSO,DC=COM"
-Partition "CN=Schema,CN=Configuration,DC=EUROPE,DC=TEST,DC=CONTOSO,DC=COM"
In many cases, a default value will be used for the Partition parameter if no value is specified. The rules
for determining the default value are given below. Note that rules listed first are evaluated first and once
a default value can be determined, no further rules will be evaluated.
In AD DS environments, a default value for Partition will be set in the following cases: - If the Identity
parameter is set to a distinguished name, the default value of Partition is automatically generated from this
distinguished name.
- If running cmdlets from an Active Directory provider drive, the default value of Partition is automatically
generated from the current path in the drive.
- If none of the previous cases apply, the default value of Partition will be set to the default partition or
naming context of the target domain.
In AD LDS environments, a default value for Partition will be set in the following cases:
- If the Identity parameter is set to a distinguished name, the default value of Partition is automatically
generated from this distinguished name.
- If running cmdlets from an Active Directory provider drive, the default value of Partition is automatically
generated from the current path in the drive.
- If the target AD LDS instance has a default naming context, the default value of Partition will be set to
the default naming context. 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.
- If none of the previous cases apply, the Partition parameter will not take any default value.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-PassThru [<SwitchParameter>]
Returns the new or modified object. By default (i.e. if -PassThru is not specified), this cmdlet does not
generate any output.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Server <String>
Specifies the Active Directory Domain Services instance to connect to, by providing one of the following
values for a corresponding domain name or directory server. The service may be any of the following: Active
Directory Lightweight Domain Services, Active Directory Domain Services or Active Directory Snapshot instance.
Domain name values:
Fully qualified domain name
Examples: corp.contoso.com
NetBIOS name
Example: CORP
Directory server values:
Fully qualified directory server name
Example: corp-DC12.corp.contoso.com
NetBIOS name
Example: corp-DC12
Fully qualified directory server name and port
Example: corp-DC12.corp.contoso.com:3268
The default value for the Server parameter is determined by one of the following methods in the order that
they are listed:
-By using Server value from objects passed through the pipeline.
-By using the server information associated with the Active Directory PowerShell provider drive, when running
under that drive.
-By using the domain of the computer running Windows PowerShell.
The following example shows how to specify a full qualified domain name as the parameter value.
-Server "corp.contoso.com"
