I know this is an old problem, and have found old archives mentioning the same problem. I believe there was also a samba bug logged for the problem - #756. Trouble is, I can't find any mention of a solution. The problem is to do with accessing Autocad R14 drawings over a samba share, it seems there is something non-standard/incorrect with the locking. Autocad complains (seemingly randomly) that the drawing is read only, even when UNIX permissions definately allow read/write. It has been suggested to set 'max mux' to 1 but this has had no effect, did anyone come up with a solution ?? Oh, and the problem does not appear to be platform specific, we have the same problem on Sun and Dec Alpha machines. Thanks in advance.
