Editor's Corner

This week's newsletter is all about managing Apple iOS devices in enterprise environments using the new Device Registration Service in Windows Server 2012 R2 with a guest editorial by Simon May, an Enterprise Client Evangelist at Microsoft. More and more users want to bring their personal iOS devices into the workplace because of their familiarity with the iOS platform and because of the numerous apps they've downloaded on their devices. In fact, some users seem to get so addicted to their iOS devices that they can't stop downloading apps for them! Are they crazy? This Dilbert comic strip might just have the answer:

From the Mailbag

Back in Issue #955, Keeping it simple I included my own top three observations why IT projects tend to fail. Since then several readers have chimed in with their own top three reasons for why large IT projects often fail.

Nigel, an IT Manager in New Zealand, lists his top reasons for project failure as:

  1. Scope Creep. Thinking that "while we're doing this, we may as well do that as well".
  2. IT moves so fast, and big projects take so long, that technology can pull out and pass us, meaning backtracking to fit in the latest.
  3. Not following the 6P rule - "Proper Planning Prevents P*ss-Poor Performance"

That first item (scope creep) is definitely something we all need to watch for.

Martin, an IT manager in Wien, Austria, says he's noticed the following as reasons for projects going under:

  1. The project is always too late. Most projects are discussed endlessly before the real work starts…
  2. Project targets change during the project. Big error -- you should do the changes after the project is finished, not during
  3. Staff is never enough. Most of the time business decides on budget which leads to either a shortage on number or qualification of staff. In their opinion IT is always requesting a Bentley when they believe a VW can do the same, Reality is somewhere between -- on both ends…

I like his last point that both business and IT need to meet in the middle somewhere.

Other readers can chime with their own suggestions by emailing me at wsn@mtit.com

And now on to our guest editorial by Simon May...

iOS in the Enterprise

Over the past few years the devices that we have to support in our organizations has changed, pushed forth by the notion that the devices our users want to use has evolved. Not every worker is happy to only use the devices that IT provide to them as users have become more tech-savvy. I'm not suggesting they've all become technology whiz-kids but they know more than they once did; enough to feel comfortable about owning the latest tech. Devices too have improved making much of what we used to spend our time managing far easier -- security, connectivity. To put things another way IT is starting to be able to shift focus from control to governance.

Windows is always going to be, in my opinion, the most manageable OS on any device. Microsoft started in the consumer space, was embraced by enterprise and built tools for enterprise management. Group Policy, Configuration Management tools and PowerShell all provide tools to manage almost everything about the OS. That said with the billions of smartphones, the increase in tablet usage and more we need to be thinking about managing other devices Apple iOS is chief amongst them and Apple's iOS (now on version 7) has good management built in.

Identity is the cornerstone of good governance, it's impossible to govern without knowing what you're governing and in the enterprise the key identity store for most is Active Directory. From here we assign the roles, the rights, the permissions that our domain users and devices can use. Computers and users are joined to the domain in exchange for access to files and services and to give IT management (to ease user pain / reduce TCO to the business). There is two way trust, users and computers trust the domain and the domain services trust the users and computers.

In this new world though of tech-savvy users, with devices we govern (because we often don't own them), how do we get that identity into our trusted identity store? That's where the new Device Registration Service (commonly called Work Place Join) in Windows Server 2012 R2 comes to the fore.

Preparing for Device Registration

There are a number of components needed to configure a working Device Registration Service. The architecture that we're about to implement will publish the ability to connect devices to our Active Directory Domain to the edge of our network. As such we don't want to hang a Domain Controller out on the Internet, instead we will setup Active Directory Federation Services (ADFS) so that only specific trusted services -- such as device registration -- can access our AD DS. Our ADFS server will live inside our network and as of Windows Server 2012 R2 this service can coexist with a domain controller.

ADFS has a reliance on correctly working public key infrastructure (PKI), I'm not going to go into detail on how to configure this, but we will look at getting the right certs from our enterprise CA.

The next service that's needed for this process to work is another new addition to Windows Server 2012 R2, the Web Application Proxy, which functions like a reverse proxy and as our publishing point and our ADFS proxy. This service will rely on the ability to use certificates issued to other web servers and as such it makes use of the Kerberos Constrained Delegation (KCD) feature released with Windows Server 2012.

In other words we need:

The first thing to do is to add a DNS record for our ADFS server to our internal DNS -- something like ADFS.corp.contoso.com -- pointing to our ADFS server, next we do the same to our external DNS pointing to the address of what will be our Web Application Proxy.

The next step is to setup the account that the ADFS service and latterly our Device Registration Service, will use. Introduced with Windows Server 2012 R2 were Group Managed Service Accounts (GMSA), they are special because AD manages passwords for these accounts that are changed regularly and are therefore potentially more secure than standard user accounts when used with services. On our domain controller we need to run the following PowerShell:

Add-KdsRootKey --EffectiveTime (Get-Date).AddHours(-10)

This creates the root key for the Key Distribution Service that manages our Group Managed Service Accounts within our domain. We then need to create our new group managed service account:

New-ADServiceAccount FsGmsa -DNSHostName adfs.corp.contoso.com -ServicePrincipalNames "http/adfs.corp.contoso.com"

Here we are saying that this GMSA can be used by the host adfs.corp.contoso.com and we define the name of the services that can use the GMSA.

Our next step is to request certificates for our ADFS service from our enterprise CA. To request this certificate we must already have configured our CA to allow us to request certificates where we can specify the subject name and subject alternate names on our cert and also we must be able to export the certificate and the private key. We request a cert with a subject name that matches the DNS name for our ADFS server, adfs.corp.contoso.com and with two subject alternate names adfs.corp.contoso.com and enterpriseregistration.corp.contoso.com. The second of these two must be exactly that name "enterpriseregistration" within your domain. You could also buy this cert from a root CA.

Configuring ADFS

We now add the ADFS role to our server and once it's added go to the notifications item in Server Manager to select "Configure the federation service on this server" to configure our service. We create our new ADFS farm and specify our admin account. Then when asked for our SSL certificate we select the certificate issued to adfs.corp.contoso.com that we requested previously from our CA. The Federation Service Name is taken from the cert but we can provide a friendly name for users, in my case "Contoso LTD ADFS". Then we provide our GMSA as the service account, for testing and small deployments we can use the Windows Internal Database rather than SQL and finally we finish the config with a review of the options. Our ADFS service will be started and we'll be able to access the service with the URL https://adfs.corp.contoso.com/adfs/ls/IdpInitiatedSignon.aspx

At this point we have a working ADFS environment and we can confirm that by logging into our ADFS server. If the ADFS site is considered a local intranet site (i.e added to that zone) we won't even need to provide our creds.

Image

Figure 1

Next we can add trusts for any claims aware web services that require authentication through ADFS, this can be done by adding a relying party trust in the AD FS Management console but it's not necessary for device registration.

Prepare for Web Application Proxy

The very next thing we need to do is setup our Web Application Proxy but before we do we need to allow our Web Application Proxy server to use the same certificates that are used to secure our ADFS and any intranet websites with SSL. So we need to export them from the webservers and ADFS servers they reside on and import them into the Personal certificate store of our Web Application Proxy server. This is easily done from the Certificates MMC snap in.

Image

Figure 2

We now need to allow the secure impersonation or delegated use of those certificates by the Web Application Proxy server for those certificates using KCD. From PowerShell or Command Prompt as an Administrator we run:

setspn -S http/edge.corp.contoso.com edge

This will register the SPN http/edge.corp.contoso.com for the server named "edge", we also add the short name version of this:

Setspn -S http/edge edge

Now that we've registered the SPN we can go to the user account in AD and configure delegation such that our Web Application Proxy server (called EDGE here) can act as our ADFS server (our DC in this case) and any other servers for which we publish their SSL secured websites through our Web Application Proxy.

Image

Figure 3

Configure the Device Registration Service

The device registration service is what does the magic of adding our non-domain joined devices to our domain without domain joining them. Configuration requires two lines of PowerShell:

Initialize-ADDeviceRegistration

Enable-AdfsDeviceRegistration

The first line turns the service on and when ran interactively requests the name of the GMSA we used earlier for our ADFS configuration. The second line configures Device Registration to use ADFS, we then need to go configure ADFS to pass details to Device Registration. The AD FS Management console allows us to do this by selecting the "Authentication Policies" node and then "Edit Global Primary Authentication" from the Actions pane.

Image

Figure 4

Configure Web Application Proxy

Finally we need to configure our Web Application Proxy to publish our Device Registration Service. We need to add the role to our server then configure it when prompted through Server Manager. Web Application Proxy expects ADFS to be configured already and immediately asks for the Service name, here I used ADFS.corp.contoso.com and a domain admin password to access the ADFS server, the certificate for the service is the same one previously imported and usable through KCD.

Enrolling an iOS device

Unlike on Windows 8.1 there is enrolment UI on an iOS device, instead we go to a URL that is now published by our ADFS server and onward through our Web Application Proxy on our iOS device: https://adfs.corp.contoso.com/enrollmentserver/otaprofile

If you're doing this in a lab you'll have to get your root CA cert onto your iOS device to ensure that your CA is trusted that is if it's not chainable back to a root CA that's already trusted.

Image

Figure 5

Once we've visit the URL above on our iOS device we are asked to authenticate, and a profile is downloaded to our device. Once installed the device handshakes with AD and a record is created in AD for our iOS device. A certificate is also issued to our iOS device. To find the name of the record in AD (it's a GUID) you'll need to go into your iOS devices settings, open the profile you just installed and view the common name on the certificate that was issued to your device.

From this point on we can use the new object in AD to allow access and as an authentication factor in a multifactor authentication plan, preventing users from accessing resources form unknown devices. More granular data control can be provided with Dynamic Access Control allowing only specified users access to resources if they have iOS 4 or above for example.

Summary

Hopefully this walkthrough has given you a little introduction into bringing iOS devices into the fold and giving them access to AD provided resources. If nothing else take a deeper look at ADFS -- it's going to be rare to find an enterprise without an ADFS implementation in a few years' time. There's a great lab guide for ADFS on TechNet:
