Best way to have script start up for all users in Mountain Lion?

Question

We are trying to have a simple drive mapping script start up for ALL users on a Mac Mini. What's the simplest way of going by doing this? I've tried creating a .plist in Lingon and adding it to the Library LauncherDaemons and LauncherAgents folders, but it's not starting up. Any ideas? Is there a way to do this in the Terminal? The script by itself works fine and works if we add it to the Startup Items in System Preferences, but we want this to be automatic and for all users.

Thanks.

Save a property list like this as /Library/LaunchAgents/test.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>Label</key>
        <string>test</string>
        <key>ProgramArguments</key>
        <array>
            <string>say</string>
            <string>aa</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
    </dict>
</plist>

It should be loaded automatically on the next login.

See man launchd, man launchctl, and man launchd.plist for more information.
