    Hi, :)

    some enterprises and organisation using Microsoft OCS have the need to force all client and server machines to support NTLMv2 only, for security concerns to LAN Manager and NTLMv1. Until now, it was impossible to connect the none-certified OCS phones from Snom , a Berlin based ip-phone vendor to this kind of OCS infrastructures.

    I had the luck to get hands-on the first version of Snom's OCS Edition firmware, which supports NTLMv2 now and I like to share my test results with you. If the topic is in your interest, please check out:

    Let's play it save! ;)

      Hi, ;)

      a short update on NTLMv2 / v1 behavior in snom OCS edition firmware:

      Next firmware releases will not only include NTLMv2, also the first authentification method will be NTLMv2. It will only switch back to NTLMv1 if v2 attempts are unsuccesful.

      If it works as expected, virtually all OCS infrastructure's using snom OCS edition will profit from increased security / reliability in NTLMv2, even if its not enforced. :)

      Good Luck & Regards,
      Jan

        Jan - would you have a release date for that firmware?

        I have some on-going 'NR' issues I believe would be helped by this release...


        Are you allowed to send it directly to me?


        Regards

        Paul Adams

          Paul,

          What FW you're currently on? Latest builds fixed the NR issue. It was discrepancy betnween MS documentation and actulal code...
