Detailed Description

The Show-ADAuthenticationPolicyExpression cmdlet creates or modifies an SDDL security descriptor using the Edit Access Control Conditions window.

Parameters

-AllowedToAuthenticateFrom

Indicates that the AllowedToAuthenticateFrom listings for an object are displayed in the Edit Access Control Conditions window.

-AllowedToAuthenticateTo

Indicates that the AllowedToAuthenticateTo listings for an object are displayed in the Edit Access Control Conditions window.

-AuthType<ADAuthType>

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.

-Credential<PSCredential>

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 an Active Directory 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.

-SDDL<String>

Specifies the SDDL of the security descriptor.

-Server<String>

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:

-- A fully qualified domain name
-- A NetBIOS name

Directory server values:

-- A fully qualified directory server name
-- A NetBIOS name
-- A 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

-Title<String>

Specifies a title for the SDDL security descriptor.

-Confirm

Prompts you for confirmation before running the cmdlet.

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

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)
