<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,

about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216).



INPUTS

None or System.String



This cmdlet accepts a SDDL security descriptor.





OUTPUTS

System.Object



This cmdlet outputs a SDDL security descriptor.





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



PS C:\\>Show-ADAuthenticationPolicyExpression ????????AllowedToAuthenticateFrom > someFile.txt

PS C:\\> New-ADAuthenticationPolicy testAuthenticationPolicy -UserAllowedToAuthenticateFrom (Get-Acl

.\\AuthSettings.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 AuthSettings.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.
