Synopsis
Description
You must set the Name and Precedence parameters to create a new fine grained password policy.
Method 1: Use the New-ADFineGrainedPasswordPolicy cmdlet, specify the required parameters, and set any additional property values by using the cmdlet parameters.
Method 2: Use a template to create the new object. To do this, create a new fine grained password policy object or retrieve a copy of an existing fine grained password policy object and set the Instance parameter to this object. The object provided to the Instance parameter is used as a template for the new object. You can override property values from the template by setting cmdlet parameters. For examples and more information, see the Instance parameter description for this cmdlet.
Method 3: Use the Import-CSV cmdlet with the New-ADFineGrainedPasswordPolicy cmdlet to create multiple Active Directory fine grained password policy objects. To do this, use the Import-CSV cmdlet to create the custom objects from a comma-separated value (CSV) file that contains a list of object properties. Then pass these objects through the pipeline to the New-ADFineGrainedPasswordPolicy cmdlet to create the fine grained password policy objects.
