Hi, I am managing computers on a campus, and we have clients bind to both Active Directory for authentication, and Open Driectory for managed Prefs. Users have managed mobile accounts but are made admins on their machines. The problem we are seeing is that even though a user is an admin, we can not execute installers inside mounted images, like .dmg's. The error I get is "You do not have permission to open the application "XXX"" Where XXX is the App name. Checking the permissions of the installer, the user is the owner and the permissions are read write and execute. If I drag the installer out of the dmg, and onto the desktop, it will then run fine. It seems to have something to do with mounted images. Also, if I make a local account on the machine, there are no problems, so it definently has something to do with the managed mobile accounts. Looking at a mobile users UID and GID, it is a very large number that is pulled from AD, while a local user's UID AND GID starts at 501, and climbs with each new user. I was thinking that the high UID and GID numbers might be giving me permissions problems.... any thoughts?
