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

Modify properties of a specified authentication policy
PS C:> Set-ADAuthenticationPolicy -Identity AuthPolicy01 -Description “testDesc” -UserTGTLifetimeMins 45
This command modifies the description and the UserTGTLifetimeMins properties of the specified authentication policy.
Modify properties of an authentication policy by using an Instance.
PS C:> $authPolicy = Get-ADAuthenticationPolicy -Identity AuthPolicy02
PS C:> $authPolicy.Description = ‘testDescription’
PS C:> $authPolicy.UserTGTLifetimeMins = 60
PS C:> Set-ADAuthenticationPolicy -Instance $authPolicy
This example first gets the authentication policy named AuthPolicy02 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.
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.
Replace an existing property value
PS C:> Set-ADAuthenticationPolicy AuthPolicy03 -Replace @{description=”New Description”}
This command replaces the existing description property for AuthPolicy03 with the new description specified by the Replace parameter.
