Hi Marcel,

   It is about the security configuration of the domain controller. It can
be configured to only accept NTLMv2. The change is for non Windows_SSPI.

Thank you

Sorry, I didn't follow the conversation completely even though I'm
in the topic as I'm pretty busy currently.

What cases are we talking about? Only non-Windows / non-SSPI libcurl
right? I have access to some proxy servers in a Windows domain and I have
control over them, but I don't have access to the domain controller - is
enough or do I have to configure the NTLM flavors on the domain controller
(IIRC, I read that in a previous e-mail)?
