[Samba] Samba as Domain Member: user get permission denied accessing share...

Wed Mar 9 14:17:23 UTC 2022

The UNIX permissions on the /srv/samba folder indicate that no one 
outside the domain admins group will have access to anything inside 
/srv/samba (no matter what POSIX ACLs are set or what the Windows 
permissions show).

    # chmod 775 /srv/samba

and try again.
