Hey Athan, in order to do what you want this is what I would do in my
environment; I would create the share in my smb.conf. Then create the
directory on the server. I would populate a group for using the share,
either on the server using samba-tool or using the snap-in. Then jump over
to my Windows 7 machine, go to \\MY_SERVER, right-click my share,
tab>security, and set full control permissions to CREATOR OWNER, SYSTEM,
Domain Admins, and the group that's been created for this share. I would
then instruct the people in that group that in order to access the share
they need to open a finder, click GO > Connect to Server. Then they would
need to mount the share using smb://MY_SERVER/SHARE ...they may need to
enter their AD credentials at this point.

I have no idea what the map UID, GUID implications are in directory
utility, sorry! Good luck!
