Detailed Description

The Set-ADServiceAccount cmdlet modifies the properties of an Active Directory service account. You can modify commonly used property values by using the cmdlet parameters. Property values that are not associated with cmdlet parameters can be modified by using the Add, Replace, Clear and Remove parameters.
The Identity parameter specifies the Active Directory service account to modify. You can identify a service account by its distinguished name (DN), GUID, security identifier (SID), or Security Accounts Manager (SAM) account name. You can also set the Identity parameter to an object variable such as $<localServiceAccountObject>, or you can pass an object through the pipeline to the Identity parameter. For example, you can use the Get-ADServiceAccount cmdlet to retrieve a service account object and then pass the object through the pipeline to the Set-ADServiceAccount cmdlet.
The Instance parameter provides a way to update a service account object by applying the changes made to a copy of the object. When you set the Instance parameter to a copy of an Active Directory service account object that has been modified, the Set-ADServiceAccount cmdlet makes the same changes to the original service account object. To get a copy of the object to modify, use the Get-ADServiceAccount object. When you specify the Instance parameter you should not pass the Identity parameter. For more information about the Instance parameter, see the Instance parameter description.
For more information about how the Instance concept is used in Active Directory cmdlets, see about_ActiveDirectory_Instance.
The following examples show how to modify the ServicePrincipalNames property of a service account object by using three methods:
-By specifying the Identity and the ServicePrincipalNames parameters
-By passing a service account object through the pipeline and specifying the ServicePrincipalNames parameter
-By specifying the Instance parameter.
Method 1: Modify the ServicePrincipalNames property for the AccessIndia service account by using the Identity and ServicePrincipalNames parameters.
Set-ADServiceAccount -Identity AccessIndia -ServicePrincipalNames @{Add=ACCESSAPP/india.contoso.com}
Method 2: Modify the ServicePrincipalNames property for the AccessIndia service account by passing the AccessIndia service account through the pipeline and specifying the ServicePrincipalNames parameter.
Get-ADServiceAccount -Identity "AccessIndia" | Set-ADServiceAccount -ServicePrincipalNames @{Add=ACCESSAPP/india.contoso.com}
Method 3: Modify the <property> property for the AccessIndia service account by using the Windows PowerShell command line to modify a local instance of the AccessIndia service account. Then set the Instance parameter to the local instance.
$serviceAccount = Get-ADServiceAccount -Identity "AccessIndia"
$serviceAccount.ServicePrincipalNames = @{Add=ACCESSAPP/india.contoso.com}
Set-ADServiceAccount -Instance $serviceAccount.

Parameters

AccountExpirationDate

Specifies the expiration date for an account. When you set this parameter to 0, the account never expires. This parameter sets the AccountExpirationDate property of an account object. The LDAP Display name (ldapDisplayName) for this property is accountExpires.
Use the DateTime syntax when you specify this parameter. Time is assumed to be local time unless otherwise specified. When a time value is not specified, the time is assumed to 12:00:00 AM local time. When a date is not specified, the date is assumed to be the current date. The following examples show commonly-used syntax to specify a DateTime object.
"4/17/2006"
"Monday, April 17, 2006"
"2:22:45 PM"
"Monday, April 17, 2006 2:22:45 PM"

Instance

Specifies a modified copy of a service account object to use to update the actual Active Directory service account object. When this parameter is used, any modifications made to the modified copy of the object are also made to the corresponding Active Directory object. The cmdlet only updates the object properties that have changed.
The Instance parameter can only update service account objects that have been retrieved by using the Get-ADServiceAccount cmdlet. When you specify the Instance parameter, you cannot specify other parameters that set properties on the object.
The following is an example of how to use the Get-ADServiceAccount cmdlet to retrieve an instance of the ADServiceAccount object. The object is modified by using the Windows PowerShell command line. Then the Set-ADServiceAccount cmdlet saves the changes to the Active Directory object.
Step 1: Retrieve a local instance of the object.
$serviceAccountInstance = Get-ADServiceAccount -Identity ADServiceAdmin
Step 2: Modify one or more properties of the object instance.
$serviceAccountInstance.Description = "default"
Step3: Save your changes to ADServiceAdmin.
Set-ADServiceAccount -Instance $serviceAccountInstance

Default Value:

Data Type: ADServiceAccount

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.
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.

a property that cannot be modified using a cmdlet parameter. To remove an object property, you must use the LDAP display name. You can remove more than one property by specifying a semicolon-separated list. The format for this parameter is
-Remove @{Attribute1LDAPDisplayName=value[]; Attribute2LDAPDisplayName=value[]}
For example, if you want to add the values blue and green and remove the value pink from a property with a LDAP display name of FavColors, set the Add and Remove parameters as follows.
-Add @{FavColors=Blue,Green} -Remove {FavColors=Pink}
