Get-ADGroup Member

Module:
addsadministration
Gets the members of an Active Directory group.

Syntax 

Get-ADGroupMember
   [-AuthType <ADAuthType>]
   [-Credential <PSCredential>]
   [-Identity] <ADGroup>
   [-Partition <String>]
   [-Recursive]
   [-Server <String>]
   [<CommonParameters>]

Description

The Get-ADGroupMember cmdlet gets the members of an Active Directory group. Members can be users, groups, and computers.

The Identity parameter specifies the Active Directory group to access. You can identify a group by its distinguished name, GUID, security identifier, or Security Account Manager (SAM) account name. You can also specify the group by passing a group object through the pipeline. For example, you can use the Get-ADGroup cmdlet to get a group object and then pass the object through the pipeline to the Get-ADGroupMember cmdlet.

If the Recursive parameter is specified, the cmdlet gets all members in the hierarchy of the group that do not contain child objects. For example, if the group SaraDavisReports contains the user KarenToh and the group JohnSmithReports, and JohnSmithReports contains the user JoshPollock, then the cmdlet returns KarenToh and JoshPollock.

For Active Directory Lightweight Directory Services (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 object ( nTDSDSA ) for the AD LDS instance.

Required Parameters

-Identity

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. The acceptable values for this parameter are:

  • A distinguished name
  • A GUID (objectGUID)
  • A security identifier (objectSid)
  • A Security Account Manager account name (sAMAccountName)

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.

Type: ADGroup
Position: 0
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False

Optional Parameters

-AuthType

Specifies the authentication method to use. The acceptable values for this parameter are:

  • 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.

Type: ADAuthType
Parameter Sets: Negotiate, Basic
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-Credential

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 module for Windows 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.

If the acting credentials do not have directory-level permission to perform the task, Active Directory module for Windows PowerShell returns a terminating error.

Type: PSCredential
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-Partition

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.

In many cases, a default value is 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 are evaluated.

In Active Directory Domain Services (AD DS) environments, a default value for Partition is 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 is set to the default partition or naming context of the target domain.

In Active Directory Lightweight Directory Services (AD LDS) environments, a default value for Partition is 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 is 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 object ( nTDSDSA ) for the AD LDS instance.
  • If none of the previous cases apply, the Partition parameter does not take a default value.
Type: String
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-Recursive

Specifies that the cmdlet get all members in the hierarchy of a group that do not contain child objects.

If the specified group does not have any members, then nothing is returned.

Type: SwitchParameter
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-Server

Specifies the AD DS 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: AD LDS, AD DS, or Active Directory snapshot instance.

Specify the AD DS instance in one of the following ways:

Domain name values:

  • Fully qualified domain name
  • NetBIOS name

Directory server values:

  • Fully qualified directory server name
  • NetBIOS name
  • Fully qualified directory server name and port

The default value for this parameter is determined by one of the following methods in the order that they are listed:

  • By using the Server value from objects passed through the pipeline
  • By using the server information associated with the AD DS Windows PowerShell provider drive, when the cmdlet runs in that drive
  • By using the domain of the computer running Windows PowerShell
Type: String
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

Inputs

None or Microsoft.ActiveDirectory.Management.ADGroup

A group object is received by the Identity parameter.

Outputs

Microsoft.ActiveDirectory.Management.ADPrincipal

Returns one or more principal objects that represent users, computers or groups that are members of the specified group.

Notes

  • This cmdlet does not work with an Active Directory snapshot.
  • This cmdlet does not work when a group has members located in a different forest, and the forest does not have Active Directory Web Service running.
