[Samba] *****SPAM***** Re: Domain Member Server (wheezy) - Unable to edit permissions of share without usermapping - shall I add to Wiki?

[Shane Robinson]

Hi Davor,

If you chmod 0775 then chgrp, you are able to change the permissions from
windows while root remains the owner.

It seems, however that the above may only apply to my silly setup where I
jumped the gun and assigned a UIDnumber to Administrator, and a GIDnumber to
Domain Admins. 

I've read through your thread of October, and while I think your
requirements differ from mine, it was enlightening with respect to the
various mapping permutations.

Thanks,

If you consider 'root' as a BUILTIN\Administrator equivivalent it might work
changing both Share and DACL "the Windows way". I'm not sure it's going to
work as 'root' (on the local file/Samba server) cannot be resolved. There is
no 'SERVER\root' account in the AD database. I suggest to you to change
owner to a domain user account (or if possible a domain group). See also
