However, the fuzzer acts like smbclient and needs to establish a connection with the samba server via NTLM authentication. The NTLMSSP_Challenge sent by the server is not deterministic, which can render the fuzzing based on previously captured traffic futile. Does samba provide a fuzzing mode that uses deterministic NTLMSSP_Challenge, or how can I directly bypass the authentication stage?

That question might get more answers on the samba-technical list.

In the mean time the best answer I have is I don't think so.
Some of what you want might be possible with LD_PRELOAD or something to
intercept gnutls_rnd().
cheers,
