I am using Samba Version 3.6.0 from the Arch Linux samba 3.6.0-8 and started to have problems with Max OSX Lion clients. I only have a few, and the OSX clients are the only ones not working. I have a very simple samba setup using security = user and a single [home] (not the [homes]) share. Here is the config: [home] nt acl support = no path = /home/samba/home writable = yes guest ok = no browsable = yes create mask = 770 force create mode = 770 force security mode = 770 force directory mode = 770 directory mask = 770 valid users = @home hide dot files = yes hide unreadable = yes Windows and Linux (cifs) clients all work fine. OSX clients cannot seem to open any Word or Excel files. When I try to open a file, I get the following error: "Word cannot open this document. The document might be in use, the document might not be a valid Word document, or the file name might contain invalid characters (for example \,/). (test.doc)" The samba setup must be fine, since other files (PDF, JPG, PNG, etc) all work fine, it's just Word and Excel. Any ideas what I have screwed up? The Mac clients are using Word/Excel 2011.
