[<CommonParameters>] Description
The Set-ADFineGrainedPasswordPolicy cmdlet modifies the properties of an Active Directory fine-grained password policy. 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 fine-grained password policy to modify.
You can identify a fine-grained password policy by its distinguished name, GUID or name.
You can also set the Identity parameter to an object variable such as $<localFineGrainedPasswordPolicyObject>, 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 operator 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.
Examples
Example 1: Update properties on a fine-grained password policy object
PS C:\> Set-ADFineGrainedPasswordPolicy -Identity MyPolicy -Precedence 100 -LockoutDuration 00:40:00 -LockoutObservationWindow 00:20:00 -ComplexityEnabled $True -ReversibleEncryptionEnabled $false -MinPasswordLength 12This command updates the Precedence, LockoutDuration, LockoutObservationWindow, ComplexityEnabled, ReversibleEncryptionEnabled, and MinPasswordLength properties on the FineGrainedPasswordPolicy object with name MyPolicy.
Example 2: Set a property on a fine-grained password policy using distinguished name
PS C:\> Set-ADFineGrainedPasswordPolicy -Identity 'CN=MyPolicy,CN=Password Settings Container,CN=System,DC=FABRIKAM,DC=COM' -MinPasswordLength 12This command sets the MinPasswordLength property on the FineGrainedPasswordPolicy object with distinguished name CN=MyPolicy,CN=Password Settings Container,CN=System,DC=USER01,DC=COM.
Example 3: Get a fine-grained password policy then update a set of properties
PS C:\> $FGPP = Get-ADFineGrainedPasswordPolicy -Identity MyPolicy
PS C:\> $FGPP.LockoutObservationWindow = [TimeSpan]::Parse("0.00:15:00")
PS C:\> $FGPP.LockoutThreshold = 10
PS C:\> $FGPP.MinPasswordLength = 8
PS C:\> $FGPP.PasswordHistoryCount = 24
PS C:\> Set-ADFineGrainedPasswordPolicy -Instance $FGPPThis example gets the FineGrainedPasswordPolicy object with name MyPolicy, updates a set of properties on the object, and then writes the modifications back to the directory using the Instance parameter.
Example 4: Update a property for a specific fine-grained password policy
PS C:\> Get-ADFineGrainedPasswordPolicy -Identity "Level3Policy" | Set-ADFineGrainedPasswordPolicy -Precedence 150This command modifies the Precedence property for the fine-grained password policy named Level3Policy. The command uses the Get-ADFineGrainedPasswordPolicy cmdlet to get the fine-grained password policy, and then passes the policy to the current cmdlet by using the pipeline operator.

-Precedence
Specifies a value that defines the precedence of a fine-grained password policy among all fine-grained password policies. This parameter sets the Precedence property for a fine-grained password policy. The LDAP display name (ldapDisplayName) for this property is msDS-PasswordSettingsPrecedence.
This value determines which password policy to use when more than one password policy applies to a user or group. When there is a conflict, the password policy that has the lower Precedence property value has higher priority. For example, if PasswordPolicy1 has a Precedence property value of 200 and PasswordPolicy2 has a Precedence property value of 100, PasswordPolicy2 is used.
Typically, password policy precedence values are assigned in multiples of 10 or 100, making it easier to add policies at a later time. For example, if you set the initial precedence values for your policies to 100 and 200, you can add another policy that has precedence value of 150.
If the specified Precedence parameter is already assigned to another password policy object, the cmdlet returns a terminating error.
