Incorrect permissions on folder mapped from Windows

Question

Hi,
I have a setup with users who authenticate against a Windows AD and then access folders on a Windows 2003 server. Generally this is working, but there is a problem with a write-only folder.
When they try to copy files to that folder it first asks for the administrator password and then says "One or more items can't be copied to <Folder Name> because you don't have permission to read them. Do you want to copy the items you are allowed to read?" It then creates a 0kb file whatever you do. cp from the terminal gives a permission denied error, and also creates a 0kb file.
The permissions on the folder are the permissions of the share, plus
<username> read & write
<domain>\domain users read & write
everyone read & write
Is there any way to get OS X to use the permissions of the share rather than trying to use its own, invalid ones.
Thanks.

You might try unlocking the window and attempt to delete the custom users. Be sure to back up your system before attempting anything.
Highlight the first one and see if you can hit the minus sign to delete it. The system user should be the owner. if you highlight it and click on the triangle at the bottom, it should have "make system the owner" available is it already isn't. If the system user with the Custom priviledges is the owner, you will have to change that first before you can delete it.
You might also try resetting user permissions and see if that helps. This should be the same for ML:
Repairing User Permissions in OS X Lion
You’ll need to reboot to perform this, and then use the same resetpassword utility that is used to change passwords in Lion, but instead choosing a hidden option.
When you use the Disk Utility app and Repair Permissions — it doesn’t actually repair the permission settings on folders and files in your Home folder where your documents and personal applications reside.
In Lion, there is an additional Repair Permissions application utility hidden away. This tool is located inside boot Repair Utilities. Here’s how to access it.
Restart Lion and hold down the Command and R keys.
You will boot into the Repair Utilities screen. On top, in the Menu Bar click the Utilities item then select Terminal.
In the Terminal window, type resetpassword and hit Return.
The Password reset utility launches, but you’re not going to reset the password. Instead, click on the icon for your Mac’s hard drive at the top. From the drop-down below it, select the user account where you are having issues.
At the bottom of the window, you’ll see an area labeled ‘Reset Home Directory Permissions and ACLs’. Click the Reset button there.
The reset process takes a couple of minutes. When it’s done, quit the programs you’ve opened and restart your Mac. Notice that ‘Spotlight’ starts re-indexing immediately.
