Description

The New-ADServiceAccount cmdlet creates a new Active Directory managed service account. By default, the cmdlet creates a group managed service account. To create a delegated managed service account, use the CreateDelegatedServiceAccount parameter. Delegated managed service accounts can be used to migrate services that use normal user accounts. To create a standalone managed service account which is linked to a specific computer, use the RestrictToSingleComputer parameter. To create a group managed service account which can only be used in client roles, use the RestrictToOutboundAuthenticationOnly parameter. This creates a group managed service account that can be used for outbound connections only and any attempts to connect to services using this account will fail because the account doesn't have enough information for authentication. You can set commonly used managed service account property values by using the cmdlet parameters. Property values that aren't associated with cmdlet parameters can be set by using the OtherAttributes parameter.

The Path parameter specifies the container or organizational unit (OU) for the new managed service account object. When you Don�t specify the Path parameter, the cmdlet creates an object in the default managed service accounts container for managed service account objects in the domain.

The following methods explain different ways to create an object by using this cmdlet.

  • Method 1: Use the New-ADServiceAccount cmdlet, specify the required parameters, and set any additional property values by using the cmdlet parameters.

  • Method 2: Use a template to create the new object. To do this, create a new managed service account object or retrieve a copy of an existing managed service account object and set the Instance parameter to this object. The object provided to the Instance parameter is used as a template for the new object. You can override property values from the template by setting cmdlet parameters. For examples and more information, see the Instance parameter description for this cmdlet.

  • Method 3: Use the Import-Csv cmdlet with the New-ADServiceAccount cmdlet to create multiple Active Directory managed service account objects. To do this, use the Import-CSV cmdlet to create the custom objects from a comma-separated value (CSV) file that contains a list of object properties. For more information, type Get-Help Import-CSV. Then pass these objects through the pipeline to the New-ADServiceAccount cmdlet to create the managed service account objects.

Examples

Example 1: Create an enabled managed service account

New-ADServiceAccount -Name "Service01" -DNSHostName "Service01.contoso.com" -Enabled $True

This command creates an enabled managed service account in Active Directory Domain Services (AD DS).

Example 2: Create a managed service account and register its service principal name

$params = @{
    Name = "Service01"
    ServicePrincipalNames = "MSSQLSVC/Machine3.corp.contoso.com"
    DNSHostName = "Service01.contoso.com"
}
New-ADServiceAccount @params

This command creates a managed service account and registers its service principal name.

Example 3: Create a managed service account for a single computer

New-ADServiceAccount -Name "Service01" -RestrictToSingleComputer

This command creates a managed service account and restricts its use to a single computer.

Example 4: Create a managed service account for outbound authentication only

New-ADServiceAccount -Name "Service01" -RestrictToOutboundAuthenticationOnly

This command creates a managed service account and restricts its use to outbound authentication.

Example 5: Create a new managed service account and register multiple service principal names

$params = @{
    Name = "Service01"
    ServicePrincipalNames = "HTTP/Machine3.corp.contoso.com","HTTP/Machine3.corp.contoso.com/contoso"
    DNSHostName = "Service01.contoso.com"
}
New-ADServiceAccount @params

This command creates a delegated managed service account.

Example 6: Create an enabled delegated managed service account to be used for migration

$params = @{
    Name = "Service01"
    DNSHostName = "Service01.contoso.com"
    Enabled = $True
    CreateDelegatedServiceAccount = $True
}
New-ADServiceAccount @params

Parameters

-AccountExpirationDate

Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Path

Specifies the X.500 path of the organizational unit (OU) or container where the new object is created.

In many cases, a default value will be used for the Path 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 AD DS environments, a default value for Path is set in the following cases:

  • If the cmdlet is run from an Active Directory PowerShell provider drive, the parameter is set to the current path of the provider drive.
  • If the cmdlet has a default path, this is used. For example: in New-ADUser, the Path parameter defaults to the Users container.
  • If none of the previous cases apply, the default value of Path is set to the default partition or naming context of the target domain.

In AD LDS environments, a default value for Path is set in the following cases:

  • If the cmdlet is run from an Active Directory PowerShell provider drive, the parameter is set to the current path of the provider drive.
  • If the cmdlet has a default path, this is used. For example: in New-ADUser, the Path parameter defaults to the Users container.
  • If the target AD LDS instance has a default naming context, the default value of Path 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 Path parameter doesn't take any default value.

Note: The Active Directory Provider cmdlets, such as New-Item, Remove-Item, Remove-ItemProperty, Rename-Item, and Set-ItemProperty, also contain a Path property. However, for the provider cmdlets, the Path parameter identifies the path of the actual object and not the container as with the Active Directory cmdlets.
