Description

The Enable-DAOtpAuthentication cmdlet enables one-time password (OTP) authentication for DirectAccess (DA) users, and configures OTP settings.

Examples

Example 1 

PS C:\>Enable-DAOtpAuthentication -RadiusServer rsa.corp.contoso.com -SharedSecret abcd123$ -CAServers dc1.corp.contoso.com\corp-DC1-CA -CertificateTemplateName DAOTPLogon -PassThru -Force
OtpStatus               : Enabled 
CAServers               : {dc1.corp.contoso.com\corp-DC1-CA} 
CertificateTemplateName : DAOTPLogon 
RadiusServer            : {rsa.corp.contoso.com} 
UserSecuriotyGroupName  : 

If the **Force** parameter is not used, then the DA administrator is presented with the following prompt.
PS C:\>Enable-DAOtpAuthentication -RadiusServer rsa.corp.contoso.com -SharedSecret abcd123$ -CAServers dc1.corp.contoso.com\corp-DC1-CA -CertificateTemplateName DAOTPLogon -PassThru
OtpStatus               : Enabled 
CAServers               : {dc1.corp.contoso.com\corp-DC1-CA} 
CertificateTemplateName : DAOTPLogon 
RadiusServer            : {rsa.corp.contoso.com} 
UserSecuriotyGroupName  : 
 
Enabling OTP authentication will change DirectAccess user authentication settings. Do you want to continue? 
[Y] Yes  [N] No  [S] Suspend  [?] Help  (default is "Y"):

This example enables OTP authentication for DA users while setting the following.

-- rsa.corp.contoso.com as RADIUS or OTP server used to verify users OTP credentials.

-- dc1.corp.contoso.com\corp-DC1-CA as CA server used to enroll smart card logon short lived certificates.

-- DAOTPLogon as enroll smart card logon short lived certificates template.

All of the above settings should be set up in advance before the DA administrator can configure OTP for DA. UserSecurityGroupName is an optional setting and thus was not set which means that the two-factor authentication exemption feature is Disabled.

This cmdlet can add one new OTP Radius server each time it runs, for additional handling of Radius servers for OTP please use RemoteAccessRadius cmdlets. Note: This cmdlet will enable OTP if two-factor user authentication and computer certificates were already enabled using the Set-DAServer cmdlet. If PKI and two-factor user authentication are disabled, then this cmdlet fails. In addition enabling OTP authentication does not disable smart card or any other two-factor authentication available to the DA user.

Example 2 

PS C:\>Enable-DAOtpAuthentication -CertificateTemplateName DAOTPLogon_v2 -PassThru -Force
OtpStatus               : Enabled 
CAServers               : {dc1.corp.contoso.com\corp-DC1-CA} 
CertificateTemplateName : DAOTPLogon_v2 
RadiusServer            : {rsa.corp.contoso.com} 
UserSecuriotyGroupName  :

This example enables OTP authentication for DA users while keeping the OTP settings for RadiusServer and CAServers that were set before OTP authentication was disabled. The CertificateTemplateName setting was updated to the new value.

The new smart card logon short lived certificates template should be created before running this cmdlet.

Optional Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

Type: SwitchParameter
Position: Named
Default value: None
Accept pipeline input: False

Accept wildcard characters: False
-CertificateTemplateName

Specifies the name of the certificate template used for OTP certificate enrollment.

Type: String
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Prompts you for confirmation before running the cmdlet.

Type: SwitchParameter

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type: SwitchParameter
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-RadiusPort

Specifies the RADIUS server port listening for authentication requests.

Type: UInt16
Aliases: Port
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-RadiusServer

Specifies the IPv4 or IPv6 address, or the fully qualified domain name (FQDN), of the RADIUS server used for OTP authentication.

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Outputs

Microsoft.Management.Infrastructure.CimInstance#DAOtpAuth

The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign ( # ) provides the namespace and class name for the underlying WMI object.

The object contains the following OTP authentication configuration settings:

-- OtpStatus specifies whether OTP authentication is enabled or disabled.

-- RadiusServer specifies OTP RADIUS server names and addresses.

-- UserSecurityGroupName specifies security group of users exempt from two-factor authentication.

-- CAServer specifies the CA servers used for OTP authentication.

-- CertificateTemplateName specifies the name of the OTP certificate template.

-- SigningCertificateTemplateName specifies the name of the certificate template used to enroll the certificate used by Remote Access to sign certificates used for OTP authentication.
