Interesting share, are you aware that basically 'read only' and
'wrtable' are the same thing. writable by default is set to 'yes' and
read only is set to 'no' or in other words, the share by default is
un-writeable by anyone. As it set above 'read only = no' allows writing
to the share, but this is immediately turned off by 'writable = no'

Now there is the parameter 'store dos attributes' in global (which you
haven't shown us) and by default this is set to 'yes' and, unless you
have set it 'no', this means that 'map readonly' will be ignored.

What the above means is, you might as well remove the last two lines
from the share.

User shares are not reflected on the smb.conf, so reloading the config
will probably have no effect on those.

To a certain extent and most definitely on a DC where smbcontrol has no
effect.
