New “SharePoint 2013 and SharePoint 2010 claims encoding” topic in the TechNet Wiki

The SharePoint 2013 and SharePoint 2010 claims encoding topic is now available.

Have you ever wondered what “i:0#.w|contosochris” (or something like it) meant in the display of user sign-in information on a SharePoint site or in Unified Logging Service (ULS) log files?

Well, wonder no longer. This topic describes the syntax and encoding of these claims for both SharePoint 2013 and SharePoint 2010 Products, along with multiple examples.

The first thing you might notice about this topic is that I published it in the TechNet Wiki, rather than the TechNet Library. I did this for the following reasons:

  • This is content that applies to multiple versions of SharePoint. The organization of content in the TechNet Library is version-specific.
  • To open it up to the community to add content to the topic, such as additional locations in SharePoint where you might see claims encoding or for additional examples of encoded claims for different types of identity providers and authentication methods.
  • To serve as an example of a quick and easy topic that you can add to the TechNet Wiki. Sure, you can post this type of information to your own blog, but in the TechNet Wiki your topic can be expanded by other SharePoint experts, resulting in more definitive and technically complete information.

When you are about to publish your next blog post or other piece of SharePoint technical content, consider the following: Is this something I want my SharePoint colleagues around the world to participate in?

If so, publish it in the TechNet Wiki. All you need is a Microsoft (formerly Windows Live) account. You can still blog about it and link to your initial topic in the TechNet Wiki, with an open invitation to others to improve on your work for the benefit of all.
