Detailed Description

The Set-ADAuthenticationPolicySilo cmdlet modifies the properties of an Active Directory® Domain Services authentication policy silo. You can modify commonly used property values by using the cmdlet parameters. Property values that are not associated with cmdlet parameters can be modified by using the Add, Replace, Clear and Remove parameters.

The Identity parameter specifies the Active Directory Domain Services authentication policy to modify. You can specify an authentication policy object by using a distinguished name (DN), a GUID, or a name. You can also use the Identity parameter to specify a variable that contains an authentication policy object, or you can use the pipeline operator to pass an authentication policy object to the Identity parameter. To get an authentication policy object, use the Get-ADAuthenticationPolicy cmdlet.

Use the Instance parameter to specify an authentication policy object to use as a template for the object being modified. Do not specify both the Instance parameter and the Identity parameter.

For more information about how the Instance concept is used in Active Directory Domain Services cmdlets, type Get-Help about_ActiveDirectory_Instance.

Parameters

-Add<Hashtable>

Specifies a list of values to add to an object property. Use this parameter to add one or more values to a property that cannot be modified using a parameter. To identify an attribute, specify the LDAP Display Name defined for it in the Active Directory Domain Services schema.

Specify the attribute and the value of the attribute in the following format: @{'AttributeLDAPDisplayName'=value}.

To specify multiple values for an attribute, specify a comma separated list the values for the display name. You can specify values for more than one attribute by using semicolons to separate attribute value pairs.

When specifying the Add, Remove, Replace and Clear parameters together, the operations are performed in the following order:

-- Remove
-- Add
-- Replace
-- Clear

-Identity<ADAuthenticationPolicySilo>

Specifies an Active Directory Domain Services authentication policy silo object. Specify the authentication policy silo object in one of the following formats:

-- Distinguished Name
-- GUID
-- Name

This parameter can also get this object through the pipeline or you can set this parameter to an object instance.

-Instance<ADAuthenticationPolicySilo>

Specifies a modified copy of an ADAuthenticationPolicySilo object to use to update the actual ADAuthenticationPolicySilo object. When you specify this parameter, any modifications made to the modified copy of the object are also made to the corresponding ADAuthenticationPolicySilo object. The cmdlet only updates the object properties that have changed. When you specify the Instance parameter, you cannot specify other parameters that set properties on the object.

To get the ADAuthenticationPolicySilo object to use to update the ADAuthenticationPolicySilo on which the cmdlet runs, use the Get-ADAuthenticationPolicySilo cmdlet.

Specify the attribute and the value of the attribute in the following format: @{'AttributeLDAPDisplayName'=value}.

To specify multiple values for an attribute, specify a comma separated list the values for the display name. You can specify values for more than one attribute by using semicolons to separate attribute value pairs.

When specifying the Add, Remove, Replace and Clear parameters together, the operations are performed in the following order:

-- Domain name values:

---- Fully qualified domain name
---- NetBIOS name

-- Directory server values:

---- 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

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters.

Inputs

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

  • Microsoft.ActiveDirectory.Management.ADAccount

    This cmdlet accepts an account object.


Outputs

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

  • System.Object

Examples

Example 1: Modify an authentication policy silo

This command modifies the user authentication policy for the authentication policy silo named AuthenticationPolicySilo01.


PS C:\> Set-ADAuthenticationPolicySilo -Name AuthenticationPolicySilo01 -UserAuthenticationPolicy ‘AuthenticationPolicy1’

Example 2: Modify multiple properties of an authentication policy silo

This example first gets an authentication policy silo object and stores it in the variable named $authPolicySilo. Properties of the authentication policy silo are then modified, and finally the contents of the variable are written to the authentication policy silo by using the Instance parameter.


PS C:\> $authPolicySilo = Get-ADAuthenticationPolicySilo -Identity AuthenticationPolicySilo02
PS C:\> $authPolicySilo.Description = 'testDescription'
PS C:\> $authPolicySilo.Enforce = $False
PS C:\> Set-ADAuthenticationPolicySilo -Instance $authPolicySilo

Example 3: Modify multiple authentication policy silo objects by filtering

This example first gets all authentication policy silos that match the filter specified by the Filter parameter for Get-ADAuthenticationPolicySilo. The results of the filter are then passed to Set-ADAuthenticationPolicySilo by using the pipeline operator.


PS C:\> Get-ADAuthenticationPolicySilo -Filter 'UserAuthenticationPolicy -eq "AuthenticationPolicy01"' | Set-ADAuthenticationPolicySilo -UserAuthenticationPolicy AuthenticationPolicy02

Example 4: Replace a value in an authentication policy silo object

This command replaces the description for the authentication policy silo object named AuthenticationPolicySilo03.


PS C:\> Set-ADAuthenticationPolicySilo -Name AuthenticationPolicySilo03 -Replace @{description="New Description"}
