Active Directory Permissions Problems

Question

Hi all,
I'll be brief and to the point.
New iMacs
10.5.2
Bound to Active Directory
Login works fine
Authentication to network shares works fine (albeit slow)
But - when saving a file, let's say an HTML document in Coda, it comes up saying "You need administrative privileges to save the file, however you have permissions to replace the file".
Same in Excel, different message, but the same deal, can't modify files, but can create, delete, rename.
Same in Illustrator - only lets 'save as' and write over the top.
The permissions on the AD end are set fine to read&write. Even if I create a new file, it will save it once, then if I try and edit, same deal.
The permissions are granted as part of a 'group' - but I've added the individual username also and hasn't changed anything.
Any thoughts would be GREATLY appreciated.

I have an issue with OSX Leopard (10.5.2) , where by I can't write to NTFS shares on W2K3 servers with SMB signing turned on and IPV6 disabled for the interface.
To recreate the issue:
Create a folder named test that contains two files one named ._test.txt and test.txt on OSX and copy to an SMB share on W2k3.
This results in spurious errors about permissions and locked files.
Copying a file larger than 4k results in the error:
"The operation cannot be completed because you do not have sufficient privileges or some of the items."
Using mount_smbfs from a shell on OSX results in the error: "Permission denied"
host:~ user$ mount_smbfs //user@server/share /Volumes/test-smbmount/
Password:
host:~ user$ cp test.docx /Volumes/test-smbmount/
cp: /Volumes/test-smbmount/test.docx: Permission denied
Using smbclient from a shell on OSX results in SUCCESS!!!
host:~ user$ smbclient \\\\server\\\share -U user
Password:
Domain=DOMAIN OS=Windows Server 2003 3790 Service Pack 2 Server=http://Windows Server 2003 5.2
smb: \> put test.docx
putting file test.docx as \test.docx (784.7 kb/s) (average 784.7 kb/s)
smb: \>
There is an alternative solution if you do need to drag and drop in your gui world, it'll cost you $120

I have mailed the developer as he has obviously identified the root problem of the issue and I urged him to share his patch/resolution with Apple in the interests of the user community and a darn nice thing to do.I had a response form the developer to my request. I sent my workaround solution to the developer and stated that in my opinion the pricing for the software seems unnecessarily high based on the functionality it provides and way above what I would be willing to pay to resolve one small issue.
<developers response>
Pricing is a difficult topic to discuss -- but if you have no use for the product, any price is too much. As for reporting bugs to Apple, they'll listen to customers much sooner than they'll listen to developers. And they have some of the brightest engineers I know. If you report the bug to them, they'll likely have it fixed in the next update.
</developers response>
I couldn't find away to report the bug myself so I had a friend do it for me. The response I had back from Apple was less than satisfactory.
They believe that the issue is to do with NTFS streams and that a file containing ".com.apple.smb.streams.on" needs to be created and placed into the root of shared volumes. This is not a fix!
If you want to prevent writing the "Apple Double" files to a remote share, enter the following into a terminal:
$ defaults write com.apple.desktopservices DSDontWriteNetworkStores true
Problem still exists.

Before Mac OS X, the Mac OS used 'forked' files, which have two components: a data fork and a resource fork. The Mac OS Standard (HFS) and Mac OS Extended (HFS Plus) disk formats support forked files. When you move these types of files to other disk formats, the resource fork can be lost.
With Mac OS X, there is a mechanism called "Apple Double" that allows the system to work with disk formats that do not have a forked file feature, such as remote NFS, SMB, WebDAV directories, or local UFS volumes. Apple Double does this by converting the file into two separate files. The first new file keeps the original name and contains the data fork of the original file. The second new file has the name of the original file prefixed by a "._ " and contains the resource fork of the original file. If you see both files, the ._ file can be safely ignored. Sometimes when deleting a file, the ._ component will not be deleted. If this occurs you can safely delete the ._ file.

I am not the only one this issue. A quick peruse on http://macwindows.com/ will show that numerous people are suffering and numerous workarounds have been suggested. Sadly none of which work for me. Each work around is stranger than the previous. Such as disabling IPV6 and updating Daylight Savings Time.
The issue lies with the samba integration. I am primarily a Gentoo Linux user and this kind of bug would have been resolved almost instantly if present in open source software.
