    Windows authentication fails from Mac browser when LB is in between

    912494
      (1)     A new instance of Windows server 2008 R2 is taken and IIS server is installed.
      On IIS server, ‘Windows Authentication’ is enabled and all the other authentication (anonymous, basic) is disabled.
      (2)     From Safari browser on Mac, a IIS resource (protected by Windows Authentication) is accessed by directly accessing IIS server. The resource access is successful.
      (3)     Now a Load Balancer is configured in front of IIS server.
      (4)     From Safari browser on Mac, a IIS resource (protected by Windows Authentication) is accessed by accessing load balancer. Here IIS server prompts for username and password.

      Seems that authentication negotiation is failing between Mac browser and IIS when LB is in between. Can somebody pls know the reason / resolution for this issue ?

      Thanks
