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 PasswordNeverExpires parameter to change whether an account password could expire and to modify the ADS_UF_DONT_EXPIRE_PASSWD UAC value.

The Identity parameter specifies the Active Directory account to modify.

You can identify an account by its distinguished name, 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 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 (DSA) object (nTDSDSA) for the AD LDS instance.

Examples

Example 1: Require that a user use a password to logon

PS C:\> Set-ADAccountControl -Identity ElisaD -PasswordNotRequired $False

This command sets the flag on userAccountControl to make sure that a password is required for logon.

Example 2: Disable change password on a user account

PS C:\> Set-ADAccountControl -Identity 'CN=Elisa Daugherty,OU=HumanResources,OU=UserAccounts,DC=FABRIKAM,DC=COM' -CannotChangePassword $True

This command sets the security descriptor of the user to make sure they cannot change their own password.

Example 3: Disable delegation on a user account

PS C:\> Set-ADAccountControl -Identity SQLAdmin1 -AccountNotDelegated $True

This command sets the flag on userAccountControl to make sure that the account cannot be delegated.

Example 4: Set a user account to be trusted to authenticate for delegation

PS C:\> Set-ADAccountControl -Identity 'CN=IIS01 SvcAccount,OU=ServiceAccounts,OU=Managed,DC=FABRIKAM,DC=COM' -TrustedToAuthForDelegation $True

This command sets the flag on userAccountControl to make sure that the account is now trusted to authenticate for delegation.

Example 5: Set a specified computer to be trusted for delegation

PS C:\> Set-ADAccountControl -Identity "FABRIKAM-SRV1" -TrustedForDelegation $True

This command sets specified computer to be trusted for delegation.

Example 6: Set a user password to never expire

PS C:\> Set-ADAccountControl -Identity EvanNa -PasswordNeverExpires $True

This command sets the password of the user to never expire.

Example 7: Set a user account to require a home directory

PS C:\> Set-ADAccountControl -Identity 'CN=Evan Narvaez,OU=HumanResources,OU=UserAccounts,DC=FABRIKAM,DC=COM' -HomedirRequired $True

This command sets the user account to require a Home Directory.

Parameters

-AccountNotDelegated

Indicates 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 UAC attribute.

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

-AllowReversiblePasswordEncryption

Indicates whether reversible password encryption is allowed for the account. This parameter sets the AllowReversiblePasswordEncryption property of the account. This parameter also sets the ADS_UF_ENCRYPTED_TEXT_PASSWORD_ALLOWED flag of the Active Directory UAC attribute.

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

-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
Accepted values:Negotiate, Basic
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-CannotChangePassword

Indicates whether an account can change its password. To disallow password change by the account set this to $True. This parameter changes the Boolean value of the CannotChangePassword property of an account.

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

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Required:False
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.

  • A distinguished name
  • A GUID (objectGUID)
  • A Security Identifier (objectSid)
  • A SAM 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 account object instance.

Derived types such as the following are also accepted:

You can use MNS logon accounts to configure a multi-node cluster without using a shared disk drive.

Type:Boolean
Position:Named
Default value:None
Required:False
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 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 will not take any default value.
