How do I get an encrypted dmg on a network share to automatically mount at login?

Question

I need to mount an encrypted dmg that is stored on an SMB share to automatically mount at login.  I've got the SMB share to mount at login as a "Login Item," but I can't get the encrypted dmg to mount.
A related question:
I've got a shell script that mounts my encrypted image, copies data using rsync, and then unmounts the encrypted image.  I tried automating this using a cronjob, but cronjobs are nut run as $USER.  Since the cronjob isn't run as $USER, the cronjob does not have access to the $USER's keychain and cannot authenticate to the encrypted dmg.  Any tips on getting either of these to work?

Answer 1

I don't use SMB so I'm not sure whether this will work, but try it. Open a TextEdit window and type something like this:
smb://user:password@server/path-to-file
Make the obvious substitutions in the text, then select it and drag it to the Desktop. You should get a bookmark file. Double-click it to test. If it works, you can rename the file and put it anywhere you like. Add it to your login items.
If the above doesn't work, try again with "cifs" in place of "smb".
The "user:password@" part may not be necessary if the password is in your keychain.
