Snow Leopard, Active Directory : cannot save a file, but 'save as' is working I'm using my Mac to connect to an Active Directory drive.

When I was running on Leopard, it worked fine : I could open, modify and save files from the remote drive.

Last week I upgraded my computer to Snow Leopard (10.6.7) and since that, I'm having problems : I still can connect to the remove drives, I can open files, but when I want to save them I get the following error : "The document mydoc.txt could not be saved."

But if I do Save as and save the document under the very same name, then, it's working !

I have no idea what's wrong ! I tried to disconnect from the domain and reconnect, but I still have the problem.
I found a workaround to the problem :

The path to the document was the following :

smb://srv-fichiers1/Personnel/myhome/mydoc.txt


The problem was that I didn't have read/write access to the Personnel folder.

The administrator added read/write access to this folder and now, everything is working fine.

I agree that this is more a workaround than a real solution, but it does the trick for me !
