Office 365: MS Directory Synchronization Tool Comparison

Introduction

Over time, the number of free tools provided by Microsoft for synchronizing (and sometimes syncing back) on-premises AD and Azure AD has increased up to 3 (not to mention Azure Active Directory Connector for FIM 2010 R2):

  • Directory Sync aka DirSync
  • Azure AD Sync aka AADSync
  • Azure AD Connect aka AADConnect

While the first is apparently set for retirement and the two others would ultimately merge, it is still valuable to have a good idea of their capabilities and constraints before making the right choice for each implementation.

I will later publish the upgrade paths from DirSync to AADConnect.

Tool Comparison

The table hereunder is attempt to compare them as comprehensively as possible. Please note that 95% of credit for this comparison table go to French Directory Service MVP Maxime Rastello. Here is his original French article: DirSync vs Azure AD Sync vs Azure AD Connect : lequel choisir ?

Note: I will try to keep this table as up to date as possible at the following location: Office 365: MS Directory Synchronization Tool Comparison.

Revisiting the Microsoft Online immutable ID design decision

Hybrid Identity

Some time back I posted about Azure Active Directory synchronisation using Forefront Identity Manager (FIM) 2010 R2 and the Azure AD Connector. My focus was multi-forest deployments, but as we know this topology was required for several advanced scenarios too. Microsoft have since shipped Azure AD Synchronization Services (AADSync), soon to be rebranded Azure AD Connect (AAD Connect), which negates the need for FIM for most deployments and further solidifies the mentality that the Azure AD identity bridge should be separate from the enterprise identity management solution.

Having deployed quite a few FIM and AAD Connector topologies for large, enterprise customers, and having been involved in planning and design, implementation and deployment and post go live support and transfer to operations I have learned, the hard way, that the immutable ID design artefact is a massive consideration, too often overlooked and not understood. I talked about this in my post

Add or Modify SharePoint 2013 Search Topology using a PowerShell built User Interface

Karine Bosch's Blog

In SharePoint 2013, there is no real user interface to modify the search topology. Well, there is, but you can only use for a single server farm. If you have more servers in your SharePoint farm, you have to do this through PowerShell.

One of my South-African Premier Field Engineer colleagues Scott Stewart developed a tool on top of PowerShell WITH UI to create or modify a search topology.

Read more about it here: “Add or Modify SharePoint 2013 Search Topology using a PowerShell built User Interface

A few screenshots to get you curious 🙂

It looks like a very promising tool! Have fun with it!

Create a Real-Time IT Dashboard with PowerBIPS

Simply brilliant!

Rui Romano Blog

Last week we published on GitHub a powershell module for the new PowerBI developer REST API’s named “PowerBIPS”, download it here:

https://github.com/DevScope/powerbi-powershell-modules/

In this post I will demonstrate the ease of use of this module and show you step-by-step how to build a powershell script that upload server stats to PowerBI allowing the users to build a real-time IT dashboard like this:

image

The script is divided in the following steps (full script):

  1. Import the PowerBIPS module
  2. Get the Authentication Token
  3. Create a PowerBI DataSet
  4. Upload data to PowerBI

Import the PowerBIPS module

The script starts by importing the powershell module:

# Module need to be installed on %USERPROFILEWindowsPowershellModules
Import-Module PowerBIPS -Force

Or by pointing directly to the .psm1 file:

Import-Module <path to module>PowerBIPS.psm1 –Force

After this all the PowerBIPS cmdlets are available for use in the PowerShell console.

Get the Authentication Token

Next we need to get the…

Exchange: Network Ports and Flows References

Having recently dealt with MS Exchange vs. Firewall and flows issues, I thought it might be interesting to post a summary of useful links related to network ports and flows used by Exchange and various clients . Bottom line: Exchange and firewalls ain’t no good friends but you already knew that don’t you?

SharePoint: Perspectives on Apps (From other Blogs)

It took quite a while for the dust thrown in the air after SharePoint 2013 App model introduction to fall back on the ground.

Now it seems to become clear that apps will never become the replacement for so-called “deprecated” (always use that word cautiously) development models.

You will find hereunder a serie of worth-reading well argumented blog posts discussing around this still hot topics.

Happy reading and coding!

SharePoint: SNI vs. Windows WebDAV Client

Introduction

SNI stands for Server Name Indication, an improvement to the SSL/TLS protocol recently added to Windows (from Windows Server 2012/IIS 8). Its purpose is to allow using multiple SSL certificates on the same web server’s IP address and port. In a certain sense, you could say it is to HTTPS what host header is to HTTP. Similarly to host header, this feature must be implemented in both client and server sides because it relies in additional information’s passed as part of the SSL handshake process initiated by the client. As consequence, older browsers (as well as older client applications in general) are not compatible.

The Problem

Now SharePoint comes into the picture. One key client functionality is the Explorer View exposed by Windows WebDAV Client. Although Microsoft continuously updates its browser, the WebDAV client did not recently receive any update to support SNI. Therefore, if you configure SharePoint together with IIS to use HTTPS using SNI, Windows Explorer browsing SharePoint will simply stop functioning displaying an error such as “A device attached to the system is not functioning”. The problem will sadly occur with Windows 8 as well but is fixed from Windows 8.1.

Workarounds

There is currently no real solution and very few workarounds:

  • On IIS: Use unique combination of web application, certificate and IP address and/or port. Every time a new web application is created on SharePoint, you will have to reconfigure it on each server in the IIS configuration in order to use another IP address or another port.
  • On Windows/HTTP.sys driver: Use a fallback certificate. This blog post details the procedure to do so: How to support non-SNI capable Clients with Web Application Proxy and AD FS 2012 R2
  • On a hardware load balancer: identically to what can be done on IIS, a unique virtual IP address for each web application together with its own certificate can be used. On the SharePoint side, you can whether use no certificate at all or a used self-signed one.
