editing files on Server 2008 messes up permissions
I've run into a problem that's a bit baffling for me.
We've got several macs in our office all running 10.7.2. All of these macs connect to a windows 2008 server over SMB.
We're not having any problems connecting to the shares and getting to files, where we are running into problems is that when one of these macs saves changes to a file, the file gets a random account added to it's ACL that isn't part of our Active Directory. It's showing up as "Account Unknown(S-1-5-88-3-448)" and it gets added regardless of who edits the file or which computer the editing is done on.
This account is set to Deny and has no priviledges whatsoever on the file and is causing other users to no longer be able to edit the file.
If I go in on a windows machine and remove the offending account from the ACL on the file, it begins working properly again.
This has only started happening since we upgraded to 10.7.
Anyone have any ideas?
