Inputs

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

  • None or System.String

    This cmdlet accepts a SDDL security descriptor.


Outputs

The output type is the type of the objects that the cmdlet emits.

  • System.Object

Examples

Example 1: Retrieve the AllowedToAuthenticateFrom settings and store in a file

This command retrieves the AllowedToAuthenticateFrom access control list (ACL) by opening the Edit Access Control Conditions window and stores the ACL in a file named AuthSettings.txt. The file is then used to apply a new authentication policy to the retrieved ACL.


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

Example 2: Set the UserAllowedToAuthenticateFrom property

This example uses the New-ADAuthenticationPolicy cmdlet to create an authentication policy, and then sets the UserAllowedToAuthenticateFrom property by specifying the Show-ADAuthenticationPolicyExpression cmdlet as the value for the parameter.


PS C:\> New-ADAuthenticationPolicy -Name "testAuthenticationPolicy" -UserAllowedToAuthenticateFrom (Show-ADAuthenticationPolicyExpression -AllowedToAuthenticateFrom)
