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, Remove, Replace, and Clear 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, 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.

Examples

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 -Identity AuthenticationPolicy03 -Replace @{description="New Description"}

This command replaces the existing description property for AuthenticationPolicy03 with the new description specified by the Replace parameter.

Parameters

-Add

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 Lightweight Directory Access Protocol (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

Type:	Hashtable
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-AuthType

Specifies the authentication method to use. The acceptable values for this parameter are:

• Negotiate or 0
• Basic or 1

The default authentication method is Negotiate. A Secure Sockets Layer (SSL) connection is required for the Basic authentication method.

Type:	ADAuthType
Accepted values:	Negotiate, Basic
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Clear

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

Type:	String[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ComputerAllowedToAuthenticateTo

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ComputerTGTLifetimeMins

Specifies the lifetime in minutes for non-renewable ticket granting tickets (TGTs) for computer accounts.

-Confirm

Prompts you for confirmation before running the cmdlet.

-Credential

Specifies a user account that has permission to perform the task. The default is the current user. Type a user 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 Services Windows 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.

Type:	PSCredential
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Description

Specifies a description for the object. This parameter sets the value of the description property for the object. The LDAP display name (ldapDisplayName) for this property is "description".

Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Enforce

Indicates whether the authentication policy is enforced. Specify $True to set the authentication policy to enforced. Specify $False to set the authentication policy to not enforced.

Type:	Boolean

Accept pipeline input:	False
Accept wildcard characters:	False

-Identity

Specifies an Active Directory Domain Services authentication policy object. Specify the authentication policy object in one of the following formats:

• Distinguished Name

When you specify this parameter, any modifications made to the modified copy of 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.

Type:	ADAuthenticationPolicy
