ID4175: The issuer of the security token was not recognized...

This error is thrown by sts.
Obviously, it is error in  this section:

<issuerNameRegistry type="Microsoft.IdentityModel.Tokens.ConfigurationBasedIssuerNameRegistry, Microsoft.IdentityModel, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
  <add name="CN = test" thumbprint="12 34 56 78 89 45 45 45 45 45 44 44 44" />

At first look thubprint of certificate was OK. But when I open it in hex editor there was some characters that was not visible in text editor. I fix this and everything was OK. :)

This has bitten me more than once, so thanks for the reminder. If you are using Visual Studio, you can close your web.config, and right click on it in Solution Explorer, and choose Open With...Binary Editor.
