Detailed 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 (DN), 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 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

The following examples show how to modify the Precedence property of a fine grained password policy object by using three methods:

-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 Level3Policyfine grained password policy by using the Identity and Precedence parameters.

Set-ADFineGrainedPasswordPolicy -Identity "Level3Policy" -Precedence 150

Method 2: Modify the Precedence property for the Level3Policyfine grained password policy by passing the Level3Policyfine grained password policy through the pipeline and specifying the Precedence parameter.

Get-ADFineGrainedPasswordPolicy -Identity "Level3Policy"| Set-ADFineGrainedPasswordPolicy -Precedence 150

Method 3: Modify the Precedence property for the Level3Policy fine grained password policy by using the Windows PowerShell command line to modify a local instance of the Level3Policyfine grained password policy. Then set the Instance parameter to the local instance.

$fineGrainedPasswordPolicy = Get-ADFineGrainedPasswordPolicy Level3Policy

$fineGrainedPasswordPolicy.Precedence = 150

Set-ADFineGrainedPasswordPolicy -Instance $fineGrainedPasswordPolicy

Parameters

-Add<Hashtable>

Specifies 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 cmdlet parameter. To modify an object property, you must use the LDAP display name. You can specify multiple values to a property by specifying a comma-separated list of values and more than one property by separating them using a semicolon.. The format for this parameter is

-Add @{Attribute1LDAPDisplayName=value1, value2, ...; Attribute2LDAPDisplayName=value1, value2, ...; AttributeNLDAPDisplayName=value1, value2, ...}

For example, if you want to remove the value "555-222-2222" and add the values "555-222-1111" and "555-222-3333" to Phone-Office-Other attribute (LDAP display name 'otherTelephone'), and add the value "555-222-9999" to Phone-Mobile-Other (LDAP display name 'otherMobile'), set the Add and Remove parameters as follows.

-Add @{otherTelephone='555-222-1111', '555-222-3333'; otherMobile='555-222-9999' } -Remove @{otherTelephone='555-222-2222'}

When you use the Add, Remove, Replace and Clear parameters together, the operations will be performed in the following order:

..Remove

..Add

..Replace

-Credential<PSCredential>

Specifies the user account credentials to use to perform this task. The default credentials are the credentials of the currently logged on user unless the cmdlet is run from an Active Directory PowerShell provider drive. If the cmdlet is run from such a provider drive, the account associated with the drive is the default.

To specify this parameter, you can type a user name, such as "User1" or "Domain01\User01" or you can specify a PSCredential object. If you specify a user name for this parameter, the cmdlet prompts for a password.

You can also create a PSCredential object by using a script or by using the Get-Credential cmdlet. You can then set the Credential parameter to the PSCredential object The following example shows how to create credentials.

$AdminCredentials = Get-Credential "Domain01\User01"

The following shows how to set the Credential parameter to these credentials.

-Credential $AdminCredentials

If the acting credentials do not have directory-level permission to perform the task, Active Directory PowerShell returns a terminating error.

GUID (objectGUID)

Example: 599c3d2e-f72d-4d20-8a88-030d99495f20

Name (name)

Example: PasswordPolicyLevel1

The cmdlet searches the default naming context or partition to find the object. If two or more objects are found, the cmdlet returns a non-terminating error.

This parameter can also get this object through the pipeline or you can set this parameter to a fine-grained password policy object instance.

This example shows how to set the parameter to a distinguished name.

-Identity "CN=Strict Password Policy,CN=Password Settings Container,CN=System,DC=corp,DC=contoso,DC=com"

-Instance<ADFineGrainedPasswordPolicy>

Specifies a modified copy of a fine-grained password policy object to use to update the actual Active Directory fine-grained password policy object. When this parameter is used, any modifications made to the modified copy of the object are also made to the corresponding Active Directory object. The cmdlet only updates the object properties that have changed.

The Instance parameter can only update fine-grained password policy objects that have been retrieved by using the Get-ADFineGrainedPasswordPolicy cmdlet. When you specify the Instance parameter, you cannot specify other parameters that set properties on the object.

The following is an example of how to use the Get-ADFineGrainedPasswordPolicy cmdlet to retrieve an instance of the ADFineGrainedPasswordPolicy object. The object is modified by using the Windows PowerShell command line. Then the Set-ADFineGrainedPasswordPolicy cmdlet saves the changes to the Active Directory object.

Step 1: Retrieve a local instance of the object.

$fineGrainedPasswordPolicyInstance = Get-ADFineGrainedPasswordPolicy -Identity PasswordPolicyLevel2

Step 2: Modify one or more properties of the object instance.

$fineGrainedPasswordPolicyInstance.Precedence = 250

Step3: Save your changes to PasswordPolicyLevel2.

Set-ADFineGrainedPasswordPolicy -Instance $fineGrainedPasswordPolicyInstance

-Precedence<Int32>

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.

The following example shows how to set this parameter.

-Precedence 100

-Remove<Hashtable>

Specifies that the cmdlet remove values of an object property. Use this parameter to remove one or more values of a property that cannot be modified using a cmdlet parameter. To remove an object property, you must use the LDAP display name. You can remove more than one property by specifying a semicolon-separated list. The format for this parameter is

-Remove @{Attribute1LDAPDisplayName=value[]; Attribute2LDAPDisplayName=value[]}

For example, if you want to add the values blue and green and remove the value pink from a property with a LDAP display name of FavColors, set the Add and Remove parameters as follows.

-Add @{FavColors=Blue,Green} -Remove {FavColors=Pink}

When you use the Add, Remove, Replace and Clear parameters together, the parameters will be applied in the following sequence:
