| Is the server at any point dynamically deleting/creating/moving files or folders? If that's the case every time the file gets "changed" by the server it would reset it's permissions by giving the server ownership of the file. That is, it'd be giving the server permission because the group you users are in is different than the servers group etc.
Don't know if that will help, could be the files aren't ever being changed in any way by the server so that's irrelevant.
Hope you figure it out. |
