samba - Nov 2018 - NTLM protocol question

Hi Samba team,

    Could someone point me to a documentation which describes which NTLM flag
combination in type 1 & 2 create which type 3 response. As far as I read MS
has the following client/DC configuration combinations.

      Send LM & NTLM responses Clients use LM and NTLM authentication, and
never use NTLMv2 session security;
     DCs accept LM, NTLM, and NTLMv2 authentication. 
      Send LM & NTLM - use NTLMv2 session security if negotiated Clients use
LM and NTLM authentication, and use NTLMv2 session security if server supports
it;
     DCs accept LM, NTLM, and NTLMv2 authentication. 
      Send NTLM response only Clients use NTLM authentication only, and use
NTLMv2 session security if server supports it;
     DCs accept LM, NTLM, and NTLMv2 authentication. 
      Send NTLMv2 response only Clients use NTLMv2 authentication only, and use
NTLMv2 session security if server supports it;
     DCs accept LM, NTLM, and NTLMv2 authentication. 
      Send NTLMv2 response only\refuse LM Clients use NTLMv2 authentication
only, and use NTLMv2 session security if server supports it;
     DCs refuse LM (accept only NTLM and NTLMv2 authentication). 
      Send NTLMv2 response only\refuse LM & NTLM Clients use NTLMv2
authentication only, and use NTLMv2 session security if server supports it;
     DCs refuse LM and NTLM (accept only NTLMv2 authentication). 



but I can’t find a clear relation to the flags used during the NTLM type 1 &
2 exchange e.g. which of the flags need to be set in type 2 in particular to
determine the response in type 3.

e.g. does DCs refuse LM (accept only NTLM and NTLMv2 authentication). mean
Negotiate Lan Manager Key = 0, Negotiate NTLM key = 1 and Negotiate Extended
Security = 1
