Please see my screenshot below.

User chj executes `chmod +x ichsize.out`, but fails with **Operation not permitted**.

ichszie.out has world-rw permission enabled, but it looks not enough.

```
-rw-rw-rw-  1 nobody nogroup 27272 May 26 18:51 ichsize.out

```

The owner of ichsize.out is `nobody`, because that file is created by the Samba server, serving a `[projects]` directory location like this:

```
[projects]
        comment = VS2019 Linux-dev project output
        path = /home/chj2/projects
        browseable = yes
        read only = no
        guest ok = yes

        create mask = 0666    #(everybody: read+write)
        directory mask = 0777 #(everybody: list+modify+traverse)
        hide dot files = no

```

The Samba client accessed this share with guest identity, and requested creating the ichsize.out file.

The system is Raspberry Pi based on Debian version: 11 (bullseye). Ubuntu 20.04 exhibits the same.

So I'd like to know, how can I write my smb.conf so that any user on the RasPi can do `chmod +x` on that file.
