$false or 0

$true or 1

The following example shows how to specify that an account supports service tickets with device authorization data.

-SupportDeviceAuthz $true

Warning: Domain-joined Windows systems and services such as clustering manage their own msDS-SupportedEncryptionTypes attribute. Therefore any changes to the flag on the msDS-SupportedEncryptionTypes attribute will be overwritten by the service or system which manages the setting.

Prompts you for confirmation before running the cmdlet.

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.

Distinguished Name

Example: CN=SaraDavisDesktop,CN=Europe,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

Security Accounts Manager Account Name (sAMAccountName)

Example: SaraDavisDesktop

The cmdlet searches the default naming context or partition to find the object. If the identifier given is a DN, the partition to search will be computed from that DN. 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 a computer object instance.

This example shows how to set the parameter to a distinguished name.

-Identity "CN=saraDavisDesktop,CN=Europe,CN=Users,DC=corp,DC=contoso,DC=com"

This example shows how to set this parameter to a computer object instance named "computerInstance".

-Identity $computerInstance

Specifies a modified copy of a computer object to use to update the actual Active Directory computer 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 computer objects that have been retrieved by using the Get-ADComputer 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-ADComputer cmdlet to retrieve an instance of the ADComputer object. The object is modified by using the Windows PowerShell command line. Then the Set-ADComputer cmdlet saves the changes to the Active Directory object.

Step 1: Retrieve a local instance of the object.

$computerInstance = Get-ADComputer -Identity saraDavisDesktop

Step 2: Modify one or more properties of the object instance.

$computerInstance.Description = "Sara Davis Computer"

Step3: Save your changes to saraDavisDesktop.

Set-ADComputer -Instance $computerInstance

Specifies whether an account supports Kerberos encryption types which are used during creation of service tickets. This value sets the encryption types supported flags of the Active Directory msDS-SupportedEncryptionTypes attribute. Possible values for this parameter are:

None

None, will remove all encryption types from the account which may result in the KDC being unable to issue service tickets for services using the account.

DES is a weak encryption type which is not supported by default since Windows 7 and Windows Server 2008 R2.

The following example shows how to specify that an account supports service tickets with device authorization data.

-KerberosEncryptionTypes RC4|AES128|AES256

Warning: Domain-joined Windows systems and services such as clustering manage their own msDS-SupportedEncryptionTypes attribute. Therefore any changes to the flag on the msDS-SupportedEncryptionTypes attribute will be overwritten by the service or system which manages the setting.

The following example shows how to specify this parameter.

-OperatingSystemVersion "6.0 (6001)"

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.

Each user account has a user principal name (UPN) in the format <user>@<DNS-domain-name>. A UPN is a friendly name assigned by an administrator that is shorter than the LDAP distinguished name used by the system and easier to remember. The UPN is independent of the user object's DN, so a user object can be moved or renamed without affecting the user logon name. When logging on using a UPN, users no longer have to choose a domain from a list on the logon dialog box.

Shows what would happen if the cmdlet runs. The cmdlet is not run.
