Detailed Description

The Set-ADAuthenticationPolicy cmdlet modifies the properties of an Active Directory® Domain Services authentication policy. Commonly used attributes of the object can be specified by the parameters of this cmdlet. 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, see 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

-Credential<PSCredential>

By default, the cmdlet uses the credentials of the currently logged on user unless the cmdlet is run from an Active Directory Domain ServicesWindows PowerShell provider drive. If you run the cmdlet in a 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.

---- 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:

<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.

  • None or Microsoft.ActiveDirectory.Management.ADAuthenticationPolicy

    This cmdlet accepts an authentication policy object.


Outputs

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

  • System.Object

    Returns one or more objects.


Examples

Example 1: Modify properties of a specified authentication policy

This command modifies the description and the UserTGTLifetimeMins properties of the specified authentication policy.


PS C:\> Set-ADAuthenticationPolicy -Identity AuthenticationPolicy01 -Description "testDescription" -UserTGTLifetimeMins 45

Example 2: Modify properties of an authentication policy by using an Instance

This example first gets the authentication policy named AuthenticationPolicy02 by using the Get-ADAuthenticationPolicy cmdlet. The authentication policy object is stored in the variable named $authPolicy.

The next commands modify the properties of the object in the variable, and the final command specifies the Instance parameter to commit the changes to the authentication policy stored in the $authPolicy variable.


PS C:\> $authPolicy = Get-ADAuthenticationPolicy -Identity AuthenticationPolicy02
PS C:\> $authPolicy.Description = 'testDescription'
PS C:\> $authPolicy.UserTGTLifetimeMins = 60
PS C:\> Set-ADAuthenticationPolicy -Instance $authPolicy

Example 3: Modify multiple authentication policies

This command uses the Get-ADAuthenticationPolicy cmdlet with the Filter parameter to get all authentication policies that have the UserTGTLifetimeMins value set below 50 minutes. The pipeline operator then passes the result of the filter to Set-AdAuthenticationPolicy, which sets the new UserTGTLifetimeMins value to 60 minutes.


PS C:\> Get-ADAuthenticationPolicy -Filter 'UserTGTLifetimeMins -le 50' | Set-ADAuthenticationPolicy -UserTGTLifetimeMins 60

Example 4: Replace an existing property value

This command replaces the existing description property for AuthenticationPolicy03 with the new description specified by the Replace parameter.


PS C:\> Set-ADAuthenticationPolicy -Identity AuthenticationPolicy03 -Replace @{description="New Description"}
