Bug Description

Precise 3D 32-Bit up-to-date

What you expected to happen:
When right clicking a folder and selecting these sharing options:
* Share this folder
* Allow others to create and delete...
* Guest access
+ Modify Share
+ Adding the needed permissions by conforming that option in the upcoming dialog

it should be possible to copy any file from an other computer through the network to mine. The received files should be accessible to me as any other file in my home directory.

What happened instead:
I was able to see, mount and send a couple of images from my laptop to my precise machine. Then I tried to edit an image in my shared local folder. This wasn't possible → 'permission denied' error.

Rights of all received files inside the share:
-rwxr--r-- 1 nobody nogroup

When removing the folder from samba by unchecking the 'Share this folder' box and clicking the approval button the files inside the folder belong still to 'nobody' and 'nogroup'.

This is a show stopper, no average user would know what to do, my parents would be lost.

Suggestion:
Change file during this kind of open world samba share (everybody has rw access) to $USER:nogroup. When removing the share, the permissions should be changed to $User:$User.

Can you attach your smb.conf? That way we should be able to see if this is a bug in the configuration dialog or Samba.

I didn't change anything in my smb.conf

Sorry, my bad. I meant the usershare file that was created by the nautilus plugin.

Quite the same problem : from a system with 10.04, I try to copy files to another system with 12.04 with rsync. Always errors, because it's not permitted to write in the new folder rsync as created. And all these folders appears locked with nobody nogroup owner.
To remove them, I must use a terminal and sudo rm

Bug is still present in Wily. Followed the instructions again with Ubuntu 15.10 as host and Kubuntu 15.04 as guest.
