COMMAND EVERYTHING.
Creates an Active Directory Domain Services authentication policy object.
Microsoft ActiveDirectory reference: Creates an Active Directory Domain Services authentication policy object. The syntax and selected example below are adapted from the pinned Windows Server 2025 reference. Module availability, target configuration and delegated permissions determine whether it can run in your environment. Documentation and parameter text: Microsoft, CC BY 4.0; formatting adapted by Cmdlet World. No execution testing is claimed.
Use an account with the target resource permissions documented for New-ADAuthenticationPolicy. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

-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.
-ComputerAllowedToAuthenticateTo- Specifies the security descriptor definition language (SDDL) string of the security descriptor used to determine if the computer can authenticate to this account.
-ComputerTGTLifetimeMins- Specifies the lifetime in minutes for non-renewable ticket granting tickets (TGTs) for computer accounts.
-Confirm- Prompts you for confirmation before running the cmdlet.
-Credential- Specifies a user account that has permission to perform the task. 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. By default, the cmdlet uses the credentials of the currently logged on user unless the cmdlet is run from an Active Directory Domain Services Windows PowerShell provider drive. If you run the cmdlet in a provider drive, the account associated with the drive is the default. If you specify credentials that do not have permission to perform the task, the cmdlet returns an error.
-Description- Specifies a description for 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.
-Enforce- Indicates that the authentication policy is enforced.
-Instance- Specifies an instance of an ADAuthenticationPolicy object to use as a template for a new ADAuthenticationPolicyobject. To get the ADAuthenticationPolicy object to use as a template, use the Get-ADAuthenticationPolicy cmdlet.
-Name (required)- Specifies the name of the object. This parameter sets the Name property of the Active Directory Domain Services object. The LDAP display name (ldapDisplayName) of this property is name.
-OtherAttributes- Specifies a list of object attribute values for attributes that are not represented by other parameters. You can set one or more attributes at the same time with this parameter, and if an attribute takes more than one value you can assign multiple values. To identify an attribute, specify the LDAPDisplayName (ldapDisplayName) defined for it in the Active Directory Domain Services schema. Specify the attribute and the value of the attribute in the following format: @{'AttributeLDAPDisplayName'=value}. To specify multiple values for an attribute, specify a comma separated list the values for the display name. You can specify values for more than one attribute by using semicolons to separate attribute value pairs.
-PassThru- Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-ProtectedFromAccidentalDeletion- Indicates 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
-RollingNTLMSecret- Beginning with Windows 10, version 1703, this feature is deprecated and should not be configured in Active Directory.
-Server- Specifies the Active Directory Domain Services instance to which to connect, 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
-ServiceAllowedNTLMNetworkAuthentication- Specifies that the policy allows NTLM network authentication if the service account has an access control expression specified by the *ServiceAllowedToAuthenticateFrom* parameter.
-ServiceAllowedToAuthenticateFrom- Specifies an access control expression used to determine from which devices the service can authenticate.
-ServiceAllowedToAuthenticateTo- Specifies the SDDL string of the security descriptor used to determine if the service can authenticate to this account.
-ServiceTGTLifetimeMins- Specifies the lifetime in minutes for non-renewable TGTs for service accounts.
-UserAllowedNTLMNetworkAuthentication- Indicates that the policy allows NTLM network authentication if the user account has an access control expression specified by the *UserAllowedToAuthenticateFrom* parameter.
-UserAllowedToAuthenticateFrom- Specifies an access control expression used to determine from which devices the users can authenticate.
-UserAllowedToAuthenticateTo- Specifies the SDDL string of the security descriptor used to determine if the users can authenticate to this account.
-UserTGTLifetimeMins- Specifies the lifetime in minutes for non-renewable TGTs for user accounts.
-WhatIf- Shows what would happen if the cmdlet runs. The cmdlet is not run.
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.
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.
