Auto-mount SMB Shares on MAC with AD login credentials.

[u]Issue:[/u] Whenever my AD user logs into a mac, I want them to map smb shares automatically and place them in the dock or desktop. I want to do this without storing their passwords in clear txt, anywhere on the machine. I have seen numerous posts about doing this with a script that stores the password and username, for security reasons I cannot do this. [u]Equipment in the Golden Triangle:[/u] Mac OSX Server 10.5.6 (OD Managed AD Groups/Users) Microsoft Windows Server 2008 (AD DC) Thanks in advance for any advice.
