I have 10.6.8 server. I have about 10 users that are running 10.8.2 The problem is this - Two people can open the same file at the same time! On a PC, this would result in an access denied for one of the users. This has resulted in VERY bad situations. Is there a fix? Along the same lines, on the PC server, I could tell who the last "owner" of the file was. I do not see that on the Mac at all? Understand that we might not have configured our Mac Server correctly 15 months ago. Just need help, even if it means a 3rd party solution.
