Ok, please tell me if I'm crazy, or perhaps even stupid ... So I've been supporting Macs in a large enterprise environment for some time. I'm ACHDS certified (10.4) and just recently got my ACTC certification (10.4). I got a copy of Tiger server, setup a small internal network with a few Macs, read the entire Mac OS X Server Essentials book by Peachpit Press and did all the activities, so at least I know all this stuff *in theory*. Anyway, I'm setting up a basic file sharing server (AFP & SMB) at work using OS X Server 10.4.11 and seem to be having some problems with ACLs. For the groups I have setup with read/write permissions, they seem to be fine. They can download files from the server and modify/delete the files without any problems once on the local machine. However, groups with read-only access can download files from the server, but get an admin authentication prompt when trying to modify or delete the files. Isn't there a way to configure it so that when a user downloads the file, the ownership changes to them? Anyway, I know this may not be a very detailed description (not at work right now, don't have the server in front of me), but wondering if there are any quick tips to look out for when configuring ACLs in OS X Server. I have already propogated permissions and inheritance is enabled, so I'm not sure what's happening. Any input would be appreciated.
