[Samba] Samba Share with user and no password

[basti]

Hello,

i have migrate a Samba (3.0.20b-3.19-1616-SUSE) to debian 9 (4.5.16-Debian).

On the old suse users are created with smbpasswd -an foo
On Windows (10) users have a User account with also empthy passwords. No
AD or NT4-Domain (round about 10 Users)

Then I try to connect to the share smbclient -NL \\192.xxx.xxx.xxx work.
Connect from Windows to share with no password dosed work.

Set a Samba Password and connect to share with this works also.

I also read
https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Standalone_Server

Is there a way to connect Windows 10 with username and no password to
samba share?
