Synopsis
Description
The Identity parameter specifies the Active Directory fine grained password policy to modify. You can identify a fine grained password policy by its distinguished name (DN), GUID or name. You can also set the Identity parameter to an object variable such as $, or you can pass an object through the pipeline to the Identity parameter. For example, you can use the Get-ADFineGrainedPasswordPolicy cmdlet to retrieve a fine grained password policy object and then pass the object through the pipeline to the Set-ADFineGrainedPasswordPolicy cmdlet.
The Instance parameter provides a way to update a fine grained password policy object by applying the changes made to a copy of the object. When you set the Instance parameter to a copy of an Active Directory fine grained password policy object that has been modified, the Set-ADFineGrainedPasswordPolicy cmdlet makes the same changes to the original fine grained password policy object. To get a copy of the object to modify, use the Get-ADFineGrainedPasswordPolicy object. The Identity parameter is not allowed when you use the Instance parameter. For more information about the Instance parameter, see the Instance parameter description. For more information about how the Instance concept is used in Active Directory cmdlets, see about_ActiveDirectory_Instance
-By specifying the Identity and the Precedence parameters
-By passing a fine grained password policy object through the pipeline and specifying the Precedence parameter
-By specifying the Instance parameter.
Method 1: Modify the Precedence property for the L3Policyfine grained password policy by using the Identity and Precedence parameters.
Set-ADFineGrainedPasswordPolicy -Identity “L3Policy” -Precedence 150
Method 2: Modify the Precedence property for the L3Policyfine grained password policy by passing the L3Policyfine grained password policy through the pipeline and specifying the Precedence parameter.
Get-ADFineGrainedPasswordPolicy -Identity “L3Policy”| Set-ADFineGrainedPasswordPolicy -Precedence 150
Method 3: Modify the Precedence property for the L3Policy fine grained password policy by using the Windows PowerShell command line to modify a local instance of the L3Policyfine grained password policy. Then set the Instance parameter to the local instance.
$fineGrainedPasswordPolicy = Get-ADFineGrainedPasswordPolicy L3Policy
$fineGrainedPasswordPolicy.Precedence = 150
Set-ADFineGrainedPasswordPolicy -Instance $fineGrainedPasswordPolicy
