Detailed Description

The Set-ADAccountControl cmdlet modifies the user account control (UAC) values for an Active Directory user or computer account. UAC values are represented by cmdlet parameters. For example, set the PasswordExpired parameter to change whether an account is expired and to modify the ADS_UF_PASSWORD_EXPIRED UAC value.

The Identity parameter specifies the Active Directory account to modify.
You can identify an 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 $<localADAccountObject>, or you can pass an account object through the pipeline to the Identity parameter. For example, you can use the Search-ADAccount cmdlet to retrieve an account object and then pass the object through the pipeline to the Set-ADAccountControl cmdlet. Similarly, you can use Get-ADUser, Get-ADComputer or Get-ADServiceAccount cmdlets to retrieve account objects that you can pass through the pipeline to this 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

AccountNotDelegated

Specifies whether the security context of the user is delegated to a service. When this parameter is set to true, the security context of the account is not delegated to a service even when the service account is set as trusted for Kerberos delegation. This parameter sets the AccountNotDelegated property for an Active Directory account. This parameter also sets the ADS_UF_NOT_DELEGATED flag of the Active Directory User Account Control (UAC) attribute. Possible values for this parameter include
$false or 0
$true or 1

The following example shows how to set this parameter so that the security context of the account is not delegated to a service.
-AccountNotDelegated $true

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 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.

Identity

Specifies an Active Directory account object by providing one of the following property values. The identifier in parentheses is the LDAP display name for the attribute.

Distinguished Name
Example: CN=SaraDavis ,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
SAM Account Name (sAMAccountName)
Example: saradavis

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 account object instance.

Derived types such as the following are also accepted:
Microsoft.ActiveDirectory.Management.ADUser
Microsoft.ActiveDirectory.Management.ADComputer
Microsoft.ActiveDirectory.Management.ADServiceAccount

This example shows how to set the parameter to a distinguished name.
-Identity "CN=saradavis,CN=Users,DC=corp,DC=contoso,DC=com"

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.

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 Powershell.

The following example shows how to specify a full qualified domain name as the parameter value.
-Server "corp.contoso.com"
