and yet also using dead software ?

Also when you say 3.x, what is the 'x', from my understanding SMBv2 only
became experimental with 3.6.0

But this seems to say it isn't

Can you tell us the exact Samba version of '3.x' and post the smb.conf
of the machine you are trying to connect to.

the exact version of samba server is 3.6.6 (on debian)

and that's the smb.conf (only global section)

There have been some changes since 3.6.x (which nobody should be using now).

On 3.6.x , the default for 'ntlm auth' was 'yes', it is now
'no' on 4.11.0

 From 4.11.0 the defaults for 'client max protocol' and 'server max 
protocol' were both changed to 'SMB2_02', on 3.6.x it was
'CORE'

I think you should be able to work out how to fix your minor problem, 
but not your major problem, you need to upgrade to AD.

Microsoft has broken NT4-style domains (entirely by accident) twice to 
my knowledge, they fixed them, but they might not next time. You are 
also using smbldap-tools, this also appears to be a dead project.

setting "client min protocol = CORE" solved the problem (both for  
smbclient and nautilus)

thanks a lot for your support

(unfortunately moving to samba 4.x and AD is a very slow work in  
progress, due to the lack of time)

Glad you fixed your problem, but I would strongly advise you to find the

removed SMBv1, or a Perl update has broken smbldap-tools.
