Login Hook not working for all users

All,

I'm fairly new to macs, however I have had a lot of exposure to unix and windows systems. I'm currently trying to get a login hook to work.

I've tested my script and followed the directions on the mac support page. However, when I log in as anyone other than the login I used to create the login hook, it doesn't seem to have ran. User/Group/Other all have execute permissions as well.

Any ideas?

Thanks!
