Parameters
-AllowAll (required)
Indicates that the policy sets a claims transformation rule that would allow all claims to be sent or received.
-AllowAllExcept (required)
Specifies an array of claim types. When this parameter is specified, the policy sets a claims transformation rule that would allow all claims to be sent or received except for the specified claim types.
-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.
-Confirm
Prompts you for confirmation before running the cmdlet.
-Credential
Specifies a user account that has permission to perform this action. The default is the current user. Type a user name, such as User01 or Domain01\User01, or enter a PSCredential object, such as one generated by the Get-Credential cmdlet. You will be prompted for a password if you type a user name. This parameter is not supported by any providers installed with Windows PowerShell.
-DenyAll (required)
Indicates that the policy sets a claims transformation rule that would deny all claims to be sent or received.
-DenyAllExcept (required)
Specifies an array of claim types. When this parameter is specified, the policy sets a claims transformation rule that would deny all claims to be sent or received except for the specified claim types.
-Description
Specifies a description of the object. This parameter sets the value of the Description property for the object. The Lightweight Directory Access Protocol (LDAP) display name (ldapDisplayName) for this property is description.
-Instance
Specifies an instance of an Active Directory object to use as a template for a new claims transformation policy object. You can use an instance of an existing claims transformation policy object as a template or you can construct a new claims transformation policy object by using the Windows PowerShell command line or by using a script. Method 1: Use an existing claims transformation policy object as a template for a new object. To retrieve an instance of an existing claims transformation policy object, use the Get-ADClaimTransformPolicy cmdlet. Then provide this object to the *Instance* parameter of the New-ADClaimTransformPolicy cmdlet to create a new claims transformation policy object. You can override property values of the new object by setting the appropriate parameters. Method 2: Create a new ADClaimsTransformationPolicy object and set the property values by using the Windows PowerShell command line interface. Then pass this object to the Instance parameter of the New-ADClaimTransformPolicy cmdlet to create the new Active Directory object. Note: Specified attributes are not validated, so attempting to set attributes that do not exist or cannot be set will raise an error.
-Name (required)
Specifies the name of the object. This parameter sets the Name property of the Active Directory object. The LDAP display name (ldapDisplayName) of this property is name.
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-ProtectedFromAccidentalDeletion
Specifies whether to prevent the object from being deleted. When this property is set to $True, you cannot delete the corresponding object without changing the value of the property. The acceptable values for this parameter are: - $False or 0 - $True or 1
-Rule (required)
Specifies the claims transformation rule. To specify the rule, you can either (1) type the rule in a text file, and then pass the file to the cmdlet (recommended), or (2) type the rule inline. For instance, the following commands demonstrate how to create a new claims transformation policy object with the rule specified in a text file named Rule.txt located in a temporary folder C:\temp. $Rule = Get-Content C:\temp\rule.txt New-ADClaimTransformPolicy MyRule -Rule $Rule
-Server
Specifies the Active Directory Domain Services instance to connect to, by providing one of the following values for a corresponding domain name or directory server. The service may be any of the following: Active Directory Lightweight Domain Services, Active Directory Domain Services or Active Directory snapshot instance. Specify the Active Directory Domain Services instance in one of the following ways: Domain name values: - Fully qualified domain name - NetBIOS name Directory server values: - Fully qualified directory server name - NetBIOS name - Fully qualified directory server name and port The default value for this parameter is determined by one of the following methods in the order that they are listed: - By using the *Server* value from objects passed through the pipeline - By using the server information associated with the Active Directory Domain Services Windows PowerShell provider drive, when the cmdlet runs in that drive - By using the domain of the computer running Windows PowerShell
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
Prerequisites
Windows with the ActiveDirectory module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.
Security considerations
This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.
