       -f --flags
              Space separated NTLM flags neg-unicode:

       Indicates that Unicode strings are
              supported for use in security buffer data.

       neg-oem:
              Indicates that OEM strings are supported for use in security buffer data.

       req-target:
              Requests that the server's authentication realm be included in the Type 2 message.

       neg-sign:
              Specifies  that  authenticated  communication  between the client and server should
              carry a digital signature (message integrity).

       neg-seal:
              Specifies that authenticated communication between the client and server should  be
              encrypted (message confidentiality).

       neg-datagram-style:
              Indicates that datagram authentication is being used.

       neg-lm-key:
              Indicates  that  the Lan Manager Session Key should be used for signing and sealing
              authenticated communications.

       neg-netware:
              This flag's usage has not been identified.

       neg-ntlm-key:
              Indicates that NTLM authentication is being used.

       neg-anonymous:
              Sent by the client in the Type 3 message to indicate that an anonymous context  has
              been established. This also affects the response fields.

       neg-domain-supp:
              Sent by the client in the Type 1 message to indicate that the name of the domain in
              which the client workstation has membership is included in the  message.   This  is
              used  by  the  server  to  determine  whether  the  client  is  eligible  for local
              authentication.

       neg-workstation-supp:
              Sent by the client in the Type 1 message to indicate that the client  workstation's
              name  is  included  in the message. This is used by the server to determine whether
              the client is eligible for local authentication.

       neg-local-call:
              Sent by the server to indicate that the server and client are on the same  machine.
              Implies   that   the   client   may  use  the  established  local  credentials  for
              authentication instead of calculating a response to the challenge.

       neg-always_sign:
              Indicates that authenticated communication between the client and server should  be
              signed with a "dummy" signature.

       target-type-domain:
              Sent by the server in the Type 2 message to indicate that the target authentication
              realm is a domain.

       target-type-server:
              Sent by the server in the Type 2 message to indicate that the target authentication
              realm is a server.

       target-type-share:
              Sent by the server in the Type 2 message to indicate that the target authentication
              realm is a share.  Presumably, this is for  share-level  authentication.  Usage  is
              unclear.

       neg-ntlm2-key:
              Indicates  that  the NTLM2 signing and sealing scheme should be used for protecting
              authenticated communications.  Note  that  this  refers  to  a  particular  session
              security  scheme, and is not related to the use of NTLMv2 authentication. This flag
              can, however, have an effect on the response calculations

       req-init-res:
              This flag's usage has not been identified

       req-accept-res:
              This flag's usage has not been identified

       req-nonnt-session-key:
              This flag's usage has not been identified

       neg-target-info:
              Sent by the server in the Type 2 message to indicate that it is including a  Target
              Information  block  in  the  message.  The  Target Information block is used in the
              calculation of the NTLMv2 response.

       neg-128:
              Indicates that 128-bit encryption is supported.

       neg-key-exchange:
              Indicates that the client will provide an encrypted master key in the "Session Key"
              field of the Type 3 message.

       neg-56:
              Indicates that 56-bit encryption is supported.
