Detailed Description

The New-ADAuthenticationPolicy creates an authentication policy object in Active Directory® Domain Services.

Commonly used attributes of the object can be specified by the parameters of this cmdlet. To set attributes for the object that are not represented by the parameters of this cmdlet, specify the OtherAttributes parameter.

You can use the pipeline operator and the Import-Csv cmdlet to pass a list for bulk creation of objects in the directory. You can also specify a template object by using the Instance parameter to create objects from a template.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • System.String: System.Nullable`1[[System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], System.Management.Automation.SwitchParameter: System.Nullable`1[[System.Boolean, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]

Outputs

  • System.Object

Examples

Example 1: Create an authentication policy with a user TGT lifetime

This command creates an authentication policy object named AuthenticationPolicy01 and sets the TGT lifetime for a user account to 60 minutes. Because the Enforce parameter is not specified, the authentication policy created is in audit mode.


PS C:\> New-ADAuthenticationPolicy -Name "AuthenticationPolicy01" -UserTGTLifetimeMins 60

Example 2: Create an enforced authentication policy

This command creates an authentication policy named AuthenticationPolicy02 and enforces it by specifying the Enforce parameter.


PS C:\> New-ADAuthenticationPolicy -Name "AuthenticationPolicy02" -Enforce

Example 3: Create an authentication policy

This command creates an authentication policy named TestAuthenticationPolicy. The UserAllowedToAuthenticationFrom parameter specifies the devices from which users are allowed to authenticate by an SDDL string in the file named someFile.txt


PS C:\> New-ADAuthenticationPolicy -Name "testAuthenticationPolicy" -UserAllowedToAuthenticateFrom (Get-Acl .\someFile.txt).sddl
