Exactly as FileVault does it
Authored by: ajbaker on Dec 15, '05 04:16:30PM
After reading this entire thread, I was still left a little concerned. All of the tips result in the sparseimage being mounted as a device. This means the disk image is mounted on each users desktop with full write access! (Hardly a smart move.)

Thus I set about the quest of discovering exactly how FileVault does it. Surprisingly I couldn't find anything accurate online.

This however I think solves all the problems:

hdiutil attach /Users/username.sparseimage -stdinpass -owners on -mountpoint /Users/username -nobrowse

The differences are:
the disk image path has to go immediately after the verb attach;
-owners on specifies the permissions on the disk image should be respected;
-mountpoint is used instead of mountroot;
-nobrowse means the image is not mounted as a device in the Finder and thus not displayed in front of every user.
