Well, this is some ugly text formating, let me fix that :)

Hope someone will have an idea :) Thanks.

 Hello there. 

I'm having an issue authenticating a Windows 7 (not in a domain) against a Samba 4.1.17 (debian Jessie). It appears that the client is trying to authenticate using with it's machine name and not the user filled in the auth form. I'm using security = user and I can confirm that the share is working with Win8. Could you check my conf & the error and share me your thoughts ?

Thank you in advance, I have been searching quite some time and it's a real pain. I have seen some reg file to potentially fix the problem but I'm not comfortable with it yet.
