When you mount a share on Linux, the mount is carried out by root, so
to change the permissions, you must do it as root or with sudo. This
has nothing to do with Samba and everything to do with cifs.ko

Having said that, if the computer is domain joined, you can use
'sec=krb5' and 'multiuser', in this scenario, users can change
permissions.
