Samba 4 AD DC - a user without a password does not connect, how to fix it?

Question

linux

Such a problem, there is Samba and a domain is raised on it, I change the password policy, remove the complexity and number of characters, I do it on the server and not through RSAT and GPO. The user is created normally without a password, but I can’t log in under it, it says that the username and password are not correct. Tried on Win 7/8/10 everywhere such a problem. How to fix it? Looked everywhere for an answer and couldn't find it.

Answer 1

In the smb.conf file, in the global section, write
security = user
map to guest = bad password
, then in the same file in the balls section, write
guest ok = yes
read only = no
create mask = 0777
directory mask = 0777
