[Samba] Help to migrate from Centos 6 3.6.23-51.el6 to Debian 12 12 4.17.12-Debian

[Lorenzo Fiorini]

Hi everyone, and thanks for Samba.

I've spent several hours trying to migrate a simple Samba configuration 
from an old CentOS 6 box to a new Debian 12 box, using various online 
resources (including nearly all the AI chatbots I could find).

Here's the old CentOS 6 configuration (from |testparm|):

|[global] server string = ..... security = SHARE log file = 
/var/log/samba/log.%m max log size = 50 name resolve order = bcast 
lmhosts host wins client signing = required idmap config * : backend = 
tdb cups options = raw oplocks = No level2 oplocks = No [homes] comment 
= Home Directories read only = No browseable = No [printers] comment = 
All Printers path = /var/spool/samba printable = Yes print ok = Yes 
browseable = No [server] path = /var/server/ read only = No create mask 
= 0777 directory mask = 0777 guest ok = Yes |

The only share used is "server".
|/var/server| is owned by root:root with permissions 777
everything within |/var/server| is owned by nobody:nobody with 
permissions 777

Our issue is that Windows 11 clients are prompted for a username and 
password when connecting to the new Debian 12 box, but they aren't when 
connecting to the old CentOS 6 box.
I'm trying to determine if a completely anonymous share like this is 
still possible in Debian 12 with the newer Samba version.
It seems like it should be, but none of the configurations I've tried so 
far have worked.

Any help would be greatly appreciated.

Best regards
