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'}

or more values of a property that cannot be modified using a cmdlet parameter. To modify an object property,

you must use the LDAP display name. You can modify more than one property by specifying a comma-separated

list. The format for this parameter is



-Clear Attribute1LDAPDisplayName, Attribute2LDAPDisplayName



For example, if you want to clear the value for the Phone-Office-Other attribute (LDAP display name

'otherTelephone') set the Clear parameter as follows.



-Clear otherTelephone



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

following order:



..Remove



..Add



..Replace



..Clear



Required? false

Position? named

Default value

Accept pipeline input? false

-ComplexityEnabled <Boolean>

Specifies whether password complexity is enabled for the password policy. If enabled, the password must

contain two of the following three character types:



Uppercase characters (A, B, C, D, E, ...)



Lowercase characters (a, b, c, d, e, ...)



Numerals (0, 1, 2, 3, ...)



This parameter sets the ComplexityEnabled property of a password policy.



Possible values for this parameter include:



$false or 0 - Disables password complexity



$true or 1 - Enables password complexity



The following example shows how to set this parameter to true.



-ComplexityEnabled $true



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-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.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-Description <String>

Specifies a description of the object. This parameter sets the value of the Description property for the

object. The LDAP Display Name (ldapDisplayName) for this property is "description".

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"



This example shows how to set this parameter to a fine-grained password policy object instance named

-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

-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.

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}
