Hi Robel,

You have put up a fantastic post on using NTLM. I am authenticating with a lync server using TLS-DSK. When I request for security token, the sts is asking me to perform NTLM. I send across type 1 message to the server, to which the server sends me back type 2 message. There after reading and computing the response, I send across type 3 message. This type 3 message is rejected by the sts, and the sts is once again asking to follow up NTLM authentication. The HTTP body in while sending Type 1 and Type 3 message is same. Do you feel there is something more to it that i might be missing ?

Thx, but still I am not finished with the post.
And to your question ....See is the lync server support TLS-DSK.Because I guess you are sending TLS-DSK where the server wants NTLM.

Hi Robel,

Thanks for the reply. I think my question confused you. I want to do TLS-DSK which I can do once I get the certificate from the certificate issuer. In order to do so, I would need the certificate which I am trying to get from the WebTicketService which is hosted by the STS. Here when I make my request for the certificate, the server asks me to do NTLM. There while doing NTLM, my TYPE-3 message is rejected by the server as Unauthorized and again asks me to perform NTLM. All of this is over HTTPS.

Regards.
Naval.
