Pass authentication through from Sharepoint to Silverlight? RRS feed

  • Question

  • I have the webcontent server and the Sharepoint front end installed on two different servers.  Accessing the SSP from my domain is no problem since passthrough authentication works and works great.  The problem is if the SSP is accessed externally,  there is a login prompt for the Sharepoint site,  then another prompt for the Silverlight Webcontent server.  Is there any way to get sharepoint to pass the authenticaiton through to the silverelight site so that there would only be one login prompt?

  • This is still occurring as of now.  It is probably do to the sharepoint site and the web content server being on separate servers. With IE, passthrough works for the webcontent server so it is one prompt on the intranet.  It would be nice if the SharePoint site just passed through the authentication info though.

  • Hi Misha,

    Have you had a look at the HTTP service principal names for the portal application pool accounts? Your authentication protocol will most likely be Kerberos which requires that SPNs are added to the service accounts to allow impersonation. Have a look at How to use SPNs when you configure IIS
