NTLM Authentication to Lync RRS feed

  • Question

  • I am having trouble authenticating to an Edge server using NTLM. I have been following this Microsoft specification 

    However, in the last step of this authentication, the error happens (Screenshot of the Wireshak capture here) and the Snooper gives me this error. If you want to see the whole dialog it is available here. I don't see why it says that there is no "Authentication" header, it is clearly there and it is also pretty much the same that in the specification.

    I would really appreciate your comments. Thanks a lot

    EDIT: after tweaking a bit the SIP messages now I get HRESULT="0xC3E93EC3(SIP_E_AUTH_UNAUTHORIZED) error, I have updated the links above to reflect this. Is it something I have to do now on the server side?

    Please Help!
