DESCRIPTION

The Set-ADAuthenticationPolicy cmdlet modifies the properties of an Active Directory???? Domain Services

authentication policy. Commonly used attributes of the object can be specified by the parameters of this cmdlet.

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 Domain Services authentication policy to modify. You can

specify an authentication policy object by using a distinguished name (DN), a GUID, or a name. You can also use

the Identity parameter to specify a variable that contains an authentication policy object, or you can use the

pipeline operator to pass an authentication policy object to the Identity parameter. To get an authentication

policy object, use the Get-ADAuthenticationPolicy cmdlet.



Use the Instance parameter to specify an authentication policy object to use as a template for the object being

modified. Do not specify both the Instance parameter and the Identity parameter.



For more information about how the Instance concept is used in Active Directory Domain Services cmdlets, see

about_ActiveDirectory_Instance.





PARAMETERS

-Add <Hashtable>

Specifies a list of 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 parameter. To identify an attribute, specify the LDAP Display Name

defined for it in the Active Directory Domain Services schema.



Specify the attribute and the value of the attribute in the following format:

@{'AttributeLDAPDisplayName'=value}.



To specify multiple values for an attribute, specify a comma separated list the values for the display name.

You can specify values for more than one attribute by using semicolons to separate attribute value pairs.



When specifying the Add, Remove, Replace and Clear parameters together, the operations are performed in the

following order:



--Remove



--Add



--Replace



--Clear



Required? false

Accept pipeline input? false

Accept wildcard characters? false



-Clear <String[]>

Specifies an array of object properties that are cleared in the directory. Use this parameter to clear one or

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

specify the LDAP display name. You can modify more than one property by specifying a comma-separated list.



When specifying the Add, Remove, Replace and Clear parameters together, the operations are performed in the

following order:



--Remove



--Add



--Replace



--Clear



Required? false

Position? named

Default value

name, such as "User01" or "Domain01\\User01", or enter a PSCredential object, such as one generated by the

Get-Credential cmdlet.



By default, the cmdlet uses the credentials of the currently logged on user unless the cmdlet is run from an

Active Directory Domain ServicesWindows PowerShell provider drive. If you run the cmdlet in a provider drive,

the account associated with the drive is the default.



If you specify credentials that do not have permission to perform the task, the cmdlet returns an error.



Required? false

Position? named

Default value

Accept pipeline input? false

the object are also made to the corresponding ADAuthenticationPolicy object. The cmdlet only updates the

object properties that have changed. When you specify the Instance parameter, you cannot specify other

parameters that set properties on the object.



To get the ADAuthenticationPolicy object to use to update the ADAuthenticationPolicy on which the cmdlet runs,

use the Get-ADAuthenticationPolicy cmdlet.



Required? true

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

property, you must specify the LDAP display name.



Specify the attribute and the value of the attribute in the following format:

@{'AttributeLDAPDisplayName'=value}.

<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,

ErrorAction, ErrorVariable, WarningAction, WarningVariable,

OutBuffer, PipelineVariable, and OutVariable. For more information, see

about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216).



INPUTS

None or Microsoft.ActiveDirectory.Management.ADAuthenticationPolicy



This cmdlet accepts an authentication policy object.





OUTPUTS

System.Object



Returns one or more objects.





Example 1: Modify properties of a specified authentication policy



PS C:\\> Set-ADAuthenticationPolicy -Identity AuthenticationPolicy01 -Description "testDescription"

-UserTGTLifetimeMins 45



This command modifies the description and the UserTGTLifetimeMins properties of the specified authentication

policy.

Example 2: Modify properties of an authentication policy by using an Instance.



PS C:\\> $authPolicy = Get-ADAuthenticationPolicy -Identity AuthenticationPolicy02

PS C:\\> $authPolicy.Description = 'testDescription'

PS C:\\> $authPolicy.UserTGTLifetimeMins = 60

PS C:\\> Set-ADAuthenticationPolicy -Instance $authPolicy



This example first gets the authentication policy named AuthenticationPolicy02 by using the

Get-ADAuthenticationPolicy cmdlet. The authentication policy object is stored in the variable named $authPolicy.



The next commands modify the properties of the object in the variable, and the final command specifies the

Instance parameter to commit the changes to the authentication policy stored in the $authPolicy variable.

Example 3: Modify multiple authentication policies



PS C:\\> Get-ADAuthenticationPolicy -Filter 'UserTGTLifetimeMins -le 50' | Set-ADAuthenticationPolicy

-UserTGTLifetimeMins 60



This command uses the Get-ADAuthenticationPolicy cmdlet with the Filter parameter to get all authentication

policies that have the UserTGTLifetimeMins value set below 50 minutes. The pipeline operator then passes the

result of the filter to Set-AdAuthenticationPolicy, which sets the new UserTGTLifetimeMins value to 60 minutes.

Example 4: Replace an existing property value



PS C:\\> Set-ADAuthenticationPolicy AuthenticationPolicy03 -Replace @{description="New Description"}



This command replaces the existing description property for AuthenticationPolicy03 with the new description

specified by the Replace parameter.
