 [-Description <String>] [-Enforce] [-Instance <ADAuthenticationPolicy>] [-Name] <String>

 [-UserAllowedToAuthenticateTo <String>] [-UserAllowedNTLMNetworkAuthentication] [-UserTGTLifetimeMins <Int32>]
 [<CommonParameters>]

DESCRIPTION

The New-ADAuthenticationPolicy creates an authentication policy object in Active Directory® Domain Services.

Commonly used attributes of the object can be specified by the parameters of this cmdlet. To set attributes for the object that are not represented by the parameters of this cmdlet, specify the OtherAttributes parameter.

You can use the pipeline operator and the Import-Csv cmdlet to pass a list for bulk creation of objects in the directory. You can also specify a template object by using the Instance parameter to create objects from a template.

EXAMPLES

Example 1: Create an authentication policy with a user TGT lifetime

PS C:\> New-ADAuthenticationPolicy -Name "AuthenticationPolicy01" -UserTGTLifetimeMins 60

This command creates an authentication policy object named AuthenticationPolicy01 and sets the TGT lifetime for a user account to 60 minutes. Because the Enforce parameter is not specified, the authentication policy created is in audit mode.

Example 2: Create an enforced authentication policy

PS C:\> New-ADAuthenticationPolicy -Name "AuthenticationPolicy02" -Enforce

This command creates an authentication policy named AuthenticationPolicy02 and enforces it by specifying the Enforce parameter.

Example 3: Create an authentication policy

PS C:\> New-ADAuthenticationPolicy -Name "TestAuthenticationPolicy" -UserAllowedToAuthenticateFrom (Get-Acl .\someFile.txt).sddl

This command creates an authentication policy named TestAuthenticationPolicy. The UserAllowedToAuthenticationFrom parameter specifies the devices from which users are allowed to authenticate by an SDDL string in the file named someFile.txt.

PARAMETERS

-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
Parameter Sets: (All)
Aliases: 
Accepted values: Negotiate, Basic

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

-ComputerAllowedToAuthenticateTo

Type: String
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named

-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.

Specifies a list of object attribute values for attributes that are not represented by other parameters. You can set one or more attributes at the same time with this parameter, and if an attribute takes more than one value you can assign multiple values. To identify an attribute, specify the LDAPDisplayName (ldapDisplayName) 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.
