I just spent some time setting up my first claims based authenticated Project Server 2010 and thought I would post my experiences here, maybe that will help someone avoid the issues I had.

Firstly Bill Baer’s TechNet Blog has a great how-to article on the setup of claims-based authentication, unfortunately there are a few mistakes and omissions in the post that will cause some issues if you follow the steps as provided.

To clarify one mistake I noticed (where Bill asks you to update the Central Admin web.config twice) you must configure the web.config of the following:

  • Central Administration Web Application
  • Security Token Service
  • Your Web Application

Security Token Service Error:

Secondly when updating the Security Token Service, in my default install I found that there was no <system.web> tag, and so placing the config after the </system.net> as instructed by Bill, caused the following error when trying to login:

ProtocolException: The content type text/html; charset=utf-8 of the response message does not match the content type of the binding (application/soap+msbin1). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. T

Once I enclosed my <membership> and <rolemanager> tags in a <system.web> </system.web> all was good. Thanks to this thread for that solution.

Secure Store Error:

Finally once I got it all setup the I was getting errors trying to open my Excel data connections via Excel Services, the ULS log error was the following:

06/04/2010 12:52:42.78    w3wp.exe (0x1AA4)    0x1D94    Secure Store Service    Secure Store    7493    Critical    The Microsoft Secure Store Service application Secure Store Service failed to retrieve credentials. The error returned was ‘Access is denied.’. For more information, see the Microsoft SharePoint Products and Technologies Software Development Kit (SDK).    e994ce5b-fcde-43e8-a32b-c2427a86fc6d

This one turned out to be very simple, I forgot to add my new claims ‘role’ group to the Target Application Members configured and used by my data connections. Editing the Target Application under the Secure Store Service Application and adding to the Members those users logging in using claims fixed that one.

Share and Enjoy !
