Syntax

Show-ADAuthenticationPolicyExpression [-WhatIf] [-Confirm] [-AllowedToAuthenticateFrom] [-AuthType <ADAuthType>] [-Credential <PSCredential>] [[-SDDL] <String>] [-Server <String>] [[-Title] <String>] [<CommonParameters>]

Show-ADAuthenticationPolicyExpression [-WhatIf] [-Confirm] [-AllowedToAuthenticateTo] [-AuthType <ADAuthType>] [-Credential <PSCredential>] [[-SDDL] <String>] [-Server <String>] [[-Title] <String>] [<CommonParameters>]

————————– EXAMPLE 1 ————————–
Retrieve the AllowedToAuthenticateFrom settings and store in a file
PS C:>Show-ADAuthenticationPolicyExpression –AllowedToAuthenticateFrom > Show.txt
PS C:> New-ADAuthenticationPolicy testAuthenticationPolicy -UserAllowedToAuthenticateFrom (Get-Acl .\Setting.txt).sddl

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 Setting.txt. The file is then used to apply a new authentication policy to the retrieved ACL.

————————– EXAMPLE 2 ————————–
Set the UserAllowedToAuthenticateFrom property
PS C:>New-ADAuthenticationPolicy testAuthenticationPolicy -UserAllowedToAuthenticateFrom (Show- ADAuthenticationPolicyExpression -AllowedToAuthenticateFrom)

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.
