Previously, the Centrify Express product extended legacy, on-prem Microsoft Active Directory identities to non-Windows resources such as Mac ® and Linux ® systems as well as web applications. Centrify was essentially an add-on to on-prem Active Directory infrastructure. The latest version of Centrify's DirectControl, which can also integrate Linux and Unix systems with Active Directory, lets Macs running OS X automatically request, download and install a digital. With Centrify Management Services for Mac, you can use Active Directory to centrally manage authentication, policy enforcement, single sign-on (SSO), and user self-s ervice for popular endpoint devices running Mac OS X, macOS, iOS, and Android. A key component of Centrify Management Services for Mac is the Centrify agent for Mac computers. Aug 01, 2019 Previously, the Centrify Express product extended legacy, on-prem Microsoft Active Directory identities to non-Windows resources such as Mac ® and Linux ® systems as well as web applications. Centrify was essentially an add-on to on-prem Active Directory infrastructure.

The latest version of Centrify's DirectControl, which can also integrate Linux and Unix systems with Active Directory, lets Macs running OS X automatically request, download and install a digital certificate when accessing a corporate network via Wi-Fi or virtual private network (VPN). In addition, the upgrade makes it possible to use Active Directory credentials to unlock a Mac hard drive that's been encrypted with Apple's FireVault technology.

For government customers, DirectControl provides access to the Mac through a smartcard, typically a photo ID with a chip that provides authentication. Apple dropped the drivers for smartcards in the latest version of Mac OS X, called Lion or version 10.7, according to David McNeely, senior director of product management for Sunnyvale, Calif.-based Centrify.

Sales of Macs have been increasing steadily for some time. In the September quarter, Apple reported a 26 percent jump in sales year over year. As a result, a growing number of employees are asking to use their Macs on corporate networks, which often use Active Directory. DirectConnect provides the Mac with services available to Windows PCs. 'An administrator can manage a Mac in the same way he manages a Windows machine,' McNeely says. DirectControl pricing starts at $65 per workstation. The latest version for the Mac was introduced Tuesday.

Centrify launched its Partner Network in 2007 to establish a 'channel-friendly distribution model.' The company, which started with 25 partners, lists more than 40 resellers or consultants worldwide on its web site.

Background
The foundation to many deployment or orchestration tools is to have private hosted repositories of source installation packages. Centrify offers native packages for all the supported platforms. In addition, Centrify also offers install.sh; this script and the answer files can abstract the underlying package manager for UNIX, Linux or Mac systems.

This means that you can use an NFS Server, a Samba Server, a Web Server or your package manager in conjunction with the Centrify bits to deploy software easily across your enterprise. Alternatively, the Yellow-Dog Updater Modified (YUM) (and APT) provide a simple to set-up and robust package manager that can be used primarily with RedHat and derivative platforms.
Disclaimers
  • This article provides a 'quick basic configuration'; in a true deployment you have to account for high-availability, replication, security, package integrity, supported platforms, supported versions, change control, etc.

What is required?

Centrify Download Center

  • A RHEL-based system with enough storage for the Centrify RPM packages for each platform (or just for the subset you need to support).
  • If using web as the delivery mechanism, the web server (Apache) has to be set and configured accordingly.

Example Diagram
In my mock organization, there are different types of RHEL derivatives, including RedHatEnterprise, Fedora, Oracle, Scientific Linux, etc, all running on different architectures, including Intel (32 and 64 bit) , zLinux IBM s390, Itanium and IBM Power processors.

Implementation Steps
Verify pre-requisites. I'm planning to use http as the transport for my repo.
Install the createrepo package
Download the Centrify Bundle for the platforms to be supported.
Example data: in my mock organization, I will be supporting the bits for 2014.1 and 2015.1. This organization has a policy to only deploy maintenance releases.
  1. Go to the Centrify Customer Center and Navigate to the Downloads Section.
  2. Identity the bundle for 2015.1 and 2014.1:
    The bundle is available in ISO or ZIP formats.
  3. Copy and unzip the bundle in a staging server. Note that ALL the platforms are present. We are only interested in the .TGZ files that contain the word 'rhel' in the name.
  4. Gunzip and untar all those files (using tar xzvf package-name.tgz). You will see RPMs for all the software included. Here's a description of all packages:
    CentrifyDA is the audit agent, only used with Enterprise Edition or Privilege Service.
    CentrifyDC is adclient; can be used in Express mode or Zone mode (licensed)
    CentrifyDC is absolutely the only package required in most scenarios. Any other package, and you're in the land of 'you must know what you're doing'
    CentrifyDC-ldapproxy is the Centrified OpenLDAP Server - required to support filers or older apps over LDAP interfaces
    CentrifyDC-nis is another proxy. It exists to support legacy NIS scenarios. Needless to say, this is a transitional package, using NIS is a bad idea and will lead to audit comments.
    CentrifyDC-openssh is our provided version of OpenSSH; since SSH has matured to provide PAM, GSSAPI and even Kerberos support, 80% of the time is not needed, however, if you have an older UNIX or are in a complex AD, this package can be your friend.
Example data: If we follow the example, there should be 5 RPM packages for each of the different architecture. However, since there's variability on the s390 package releases, I ended up with 38 packages.
Tip: use the rpm -qpil command to inspect them. You'll see that they are very well docummented.
Copy the Centrify RPMs to the target location and verify access
In my over-simplistic example, we'll piggy-back on the default website.

Download Mac Browser


  1. Create a folder under /var/www/html
    $ sudo mkdir /var/www/html/centrify
  2. Copy the RPMs to the folder.$ cd /path/to/centrify/staging
    $ sudo mv * /var/www/html/centrify
  3. Set the proper permissions in the folder
    chmod -R ugo+rX /var/www/html/centrify
  4. Verify that the files are accessible via the web server (you may have to check the firewall settings)
Create your Repository
  1. Use the createrepo command to create the repository
  2. Update the repository database
Create your repository's configuration file
In this simple configuration, we ended-up with this file (centrify.repo):
Note: We are adding a keytab from a least privilege AD user that can only perform the join (or leave). This will ensure that we don't need to put any passwords, keys or hashes in our provisioning script. For more information on how to create the AD account and corresponding keytab, see this article.

Verify that your Repository is working
  1. Log in to a test system, copy or create the centrify.repo file in the /etc/yum.repos.d folder
    $ sudo cp /path/to/centrify.repo /etc/yum.repos.d/centrify.repo
  2. Checking package availability and Metadata
  3. More information about CentrifyDC (the base package) - output truncated.
    Note that I can see that the lastest version is available for two platforms that may apply to my system.
  4. Let's verify the integrity of dependencies (LDAP Proxy depends on DirectControl)
  5. Let's install DirectControl

Putting it All Together
Ultimately, there are 3 operations to onboard a Centrify system in AD.
  • Get the package and install it [we should be good here]
  • Verify that the system is ready to join (OS check, Perl, inspect DNS, check for communicaton with AD)
    [read below note #1]
  • Use the adjoin command to activate DirectControl and join AD.
    [read below note # 2]
Note # 1: With YUM you have a reliable way to get the packages across for multiple RHEL derivatives; however, your logic should include adcheck in the mix if you're not using an enterprise image. Ideally you would always do QA and use supported platforms and have a standard DNS configuration that includes the ability to get an authoritative response from a Domain controller. If that's the case, and there are no firewalls in-between, adjoin should just work.

Note # 2: We have covered adjoin extensively; keep in mind that it is Kerberized and it won't require a password to work. Its counterpart (adleave) will work the same way, and it's essential for cleanup and releasing of licenses (otherwise they will count for 45 days against your usage).
The ultimate automation script should contain just 3 lines:
  1. yum install CentrifyDC
  2. kinit to authenticate to authorized AD user
  3. adjoin
In my example:

Appendix: Flipping the script - deprovisioning
In elastic environments, decommisioning a system (or 'Terminating' in AWS lingo) has a Centrify implication; it has to do with proper Active Directory hygiene and licensing purposes(*). The proper way to leave the domain is to use the remove option of the adleave command. Based on my example, If I wanted to leave the domain and uninstall Centrify here's the sequence:
  1. kinit to an account that is authorized to remove the computer from the domain
  2. use the adleave -r command
  3. optional: use yum erase CentrifyDC
In my example:Download

(*) If you don't use the '--remove' option with adleave, you are creating an orphaned object in the zone and a computer object that is disabled. It takes 45 days for the Centrify consoles to consider this system as inactive; inactive systems don't count against your Centrify license counts. You can run the Analyze tool to find and clean orphaned and tombstoned objects.
