[Samba] Samba4 server is not accessible for logon from Windows 2008R2 SP1.

[CpServiceSPb .]

I discovered the situation.
When attempting to logon from Windows 2008R2 to Samba4 is made we can see
in Samba smbd log the following important for understanding the situation
lines:

[2017/11/20 13:25:52.040094,  2, pid=7100, effective(0, 0), real(0, 0)]
../libcli/auth/ntlm_check.c:430(ntlm_password_check)
  ntlm_password_check: NTLMv1 passwords NOT PERMITTED for user <username>
[2017/11/20 13:25:52.040110,  3, pid=7100, effective(0, 0), real(0, 0)]
../libcli/auth/ntlm_check.c:437(ntlm_password_check)
  ntlm_password_check: NEITHER LanMan nor NT password supplied for user
<username>

It tell us that Samba4 doesn't wany to accept NTLMv1 authentication.

So, it is easy to solve (as was in my case) .
You should put to smb.conf to
[general] section the followng line:
ntlm auth = yes


also I set max protocol = SMB3
but I think that it is not important for this case.

After changing smb.conf restarting of Samba4 services are necessary.

So I can mark the topic as Solved !
