Access problem to PSI WCF from browser ? RRS feed

  • Question

  • Hi,

    I got some problem to access to the PSI by WCF from browser.

    We got the common error "Access Denied" .

    When we go in ULS log we got (i pasted only information taht seems to be important):

    SharePoint Foundation        

    Claims Authentication        

    SPFederationAuthenticationModule.OnEndRequest: User was being redirected to authenticate but failed. Exception: 

    Application error when access /PWA/_vti_bin/PSI/ProjectServer.svc

    System.Web.HttpException (0x80004005): server cannot append header after http headers have been sent.

  • Found the problem.

    In IIS the possibility of anonymous logon for authentification was desactivated.
