The HTTP Request is unauthorized with client authentication scheme negotiate - MDS Excel Plugin error RRS feed

  • Question

  • Hi,

    Some users in my company are experiencing a strange issue when connecting to our MDS server using the MDS Excel plugin. They receive the error message:

    "The HTTP Request is unauthorized with client authentication scheme negotiate. The authentication header received from the server was "NTLM,BASIC real="DOMAIN NAME IWA"

    They are receiving this error when first trying to connect. For some reason they only receive this error when connected to the work network via the VPN. They don't receive this error from within our network.

    Does anyone know what might be causing this issue and how to resolve?

    Many Thanks,

    Phil
