Thinktecture IdentityServer v1.0

Yeah – it is finally done. I just uploaded the v1 bits to Codeplex and the documentation to our server. Here’s the official blurb…

Thinktecture IdentityServer is an open source security token service based on Microsoft .NET, ASP.NET MVC, WCF and WIF.

High level features

  • Multiple protocols support (WS-Trust, WS-Federation, OAuth2, WRAP, JSNotify, HTTP GET)
  • Multiple token support (SAML 1.1/2.0, SWT)
  • Out of the box integration with ASP.NET membership, roles and profile
  • Support for username/password and client certificates authentication
  • Support for WS-Federation metadata
  • Support for WS-Trust identity delegation
  • Extensibility points to customize configuration and user management handling


I did thorough testing of all features of IdentityServer – but keep in mind that this is an open source project and I am the only architect, developer and tester on the team.
IdentityServer also lacks many of the enterprise-level features like configuration services, proxy support, operations integration etc.
I only recommend using IdentityServer if you also understand how it works (to be able to support it). I am offering consulting to help you with customization and lock down – contact me.

Download. Documentation.

Up next is v1 of the Azure version. Have fun!

    Thanks for the prompt response, Dominick! When I click on the Thinktecture.IdentityServer v1.0 (source).zip package in the link provided by you, I get a ‘File Not Found’ message. Am I missing something?

    Hi Dominick,

    Sorry to bother you. I tried the download link a few times and it seems like that the package might have been permanently removed. I just wanted to check if you happen to have any other link to download the V1 identity server.

  5. I just got told from github that the zip files are gone. You can download the source code of course.
