Last week, I posted a document on how to configure User Suite to enroll devices for PKI authentication. Today we'll follow that up with a quick how-to on enabling Exchange ActiveSync with PKI Authentication.


Enabling PKI Enrollment with Centrify User Suite


With Centrify User Suite you can enable mobile devices to request a certificate for PKI authentication for either WiFi networks, and/or Exchange ActiveSync. The certificates are requested from your existing CA attached to your Active Directory, and can be used on both iOS and (supported) Android Devices.


Why should organizations use PKI based authentication?

Using certificates for authentication is much more secure than the standard username and password scheme. Users must have the proper certificate installed on the device in order to access corporate services such as WiFi and Exchange Active Sync. These certificates are stored in very secure “keyrings” on the device, and in many cases stored in a hardware secured device that thwarts tampering or removing the certificates without proper approval.

Another advantage of using certificates is that the user no longer needs to remember and enter a password to access corporate services requiring PKI based authentication.  Better security, and better user experience.


Using Centrify User Suite Microsoft Certificate Services

Set-up CA server for auto-enrollment

The following steps assume you have a working certificate services role/service within your domain. If you do not, please follow the article for setting up a CA.

This document will describe creating 2 certificates for use in device enrollment. A User certificate for Exchange/SMIME use, and a Computer certificate for device authentication into WiFi networks.



Active Directory Configuration

In Active Directory Group Policy Management snap-in,

  • Right click Default Domain Policy
  • Select Edit to open the Group Policy Management Editor


In the Group Policy Management Editor snap-in, go to “User Configuration” container

  • Expand Policies
  • Expand Windows Settings
  • Expand Security Settings
  • Select Public Key Policy


On the right pane, double click on Certificate Services Client Certificate Enrollment

Change the policy to “Enabled”. Keep others as default, click ”OK” to save it.

Do the same for “Computer Configuration” policy.


Windows Server CA Configuration

In Certification Authority snap-in,

  • Right click Certificate Templates
  • Select Manage

In Certificate Templates Console snap-in,

  • Right click on User template
  • Select Duplicate Template
  • Choose Windows Server 2003 Enterprise and click OK

In Template display name

  • In General tab, fill in the information as follows

Template Name: User-ClientAuth

  • In Security tab, make sure Domain Users has the Enroll permissions set.

In the Subject Name tab, click the “Supply in the request” radio button.



Duplicate the “Computer” certificate template, and name it “Computer-ClientAuth”, and set the same settings as above.

In Certification Authority snap-in,

  • Select “Certificate Templates”
  • Right-click and select “New->Certificate Template to Issue”




  • Select the newly created User-ClientAuth template and click OK
  • Do the same for the Comptuer-ClientAuth template



Centrify Cloud Proxy Configuration

  • Open the Centrify Cloud Proxy Configuration tool, and select the Mobile Settings Tab
  • Make sure the appropriate CA is selected for the configuration as completed above



User and Computer certificates are now configured for deployment to mobile devices, and can be used for further policy involving Microsoft ActiveSync and/or WiFi profiles. If a policy is created that requires the use of certificates, the devices will automatically request and enroll certificates.

You can then go back to the Certificate Authority tool, and check to make sure certificates are generated for mobile devices, under “Issued Certificates”.

See the Centrify documentation for configuration guides for PKI authentication for ActiveSync and WiFI.

APNS Renewal – don’t let your APNS certificate expire!


Greetings Community Members! The one year anniversary of APNS integration with Centrify for Mobile is quickly approaching and I wanted to provide some information regarding renewal of APNS certificates to avoid any loss in functionality for iOS and OS X devices.


When a new APNS certificate is created and issued by Apple, it comes with an expiration date exactly one year from the date of creation. The current APNS certificate in use must be renewed and uploaded into the Cloud Manager prior to expiration In order to continue management of currently enrolled iOS and OS X devices. Failure to renew the certificate before it expires will require a new certificate be created and all iOS devices will need to re-enroll in order to restore MDM functionality. APNS configuration is specific for Apple iOS and OS X only - does not apply to Android devices.


You can verify your current certificate expiration from the Cloud Manager under Settings > APNS Certificate. In this example, the certificate will expire on October 11, 2013 @ 6:55pm

To renew the APNS certificate, follow the steps below


  1. Login to the Cloud Manager ( and select Settings from the top menu then APNS Certificates
  2. Select the Generate Request button and download the MDM_csr.pem file when prompted
  3. Login to the Apple Push Certificates Portal at  - a valid Apple ID is required for login
  4. After login, the Manage Certificates page should be displayed. Locate the certificate that matches the expiration date displayed in the Cloud Manager


The below example shows the matching certificate is set to expire on  October 11, 2013


 APNS Certificate Manager.png



  1. Select the Renew button on the matching certificate and upload the MDM_csr.pem file downloaded in Step 2 above when prompted. DO NOT SELECT REVOKE!!
  2. After the certificate has been updated and a new expiration date is displayed in the Apple Manage Certificates page, select the Download button and save the new MDM_ Centrify Corporation_Certificate.pem file when prompted
  3. In the Cloud Manager APNS settings, select the Upload Apple Response button and upload the new MDM_ Centrify Corporation_Certificate.pem file
  4. After refreshing the Cloud Manager, the new APNS expiration should now be displayed


The updated expiration date of the renewed certificate now displays October 11, 2014 in the below example. The actual expiration will be determined by the date when the new certificate is created by Apple

After renewing and uploading the new certificate into the Cloud Manager, be sure to test MDM functions and iOS device enrollment to ensure everything is working as expected.  




If you have enrolled iOS devices , it is necessary to setup a APNS Certificate so that you can enroll iOS devices and ensure connectivity. For details on how to setup APNS Certificate refer to this video


Apple only issues certificates that are valid for 1 year from the time of issue. It is important to ensure that you renew this certificate every year before the expiry date else your iOS devices will not communicate with Centrify Cloud Service. 


To check the current expiry date follow the steps below and take steps to ensure the validity of your certificate.


1. Login to "Cloud Manager" -

2. Go to Settings 

3. Click on APNS Certificate

4. On the top you will see the "Current Expiry Date" 


7-22-2013 6-15-53 PM.jpg


5. To renew your certificate visit and follow the steps.


Additional info can also be found in the Administrators Guide on page 41




This short video will show how to configure the Group Policy and setup Exchange Active Sync for Touchdown on Android.


In order for the Centrify Cloud Service to communicate securely with your enrolled iOS devices, you need an Apple Push Notification Service (APNS) SSL certificate signed by both Centrify and Apple. An APNS cert is required before you can enroll iOS devices. This step is not required if you intend to enroll only Android devices.

  • Once the device has been enrolled its time to validate the settings on your device

This short video shows where to validate the settings 



This short video shows you an example of how to configure a prompt for a passcode for the devices before they can use the device.



  • On the host where Cloud Management Suite was installed, if the default options were selected then the installer would have also installed the Group Policy templates that can be used with GPMC.
  • Make sure GPMC is installed on the machine as well. 
  • This video shows you how to import the templates so that you can start using the settings through Group Policies
