Generate random passwords for OD users

Hi everyone, Does anybody know if it is possible to get OD to generate random passwords for all the users that do not have a password already? I need to import a list of users into OD and create different passwords for each user until the user changes the password when they first login. The passwords and usernames will also need to be visible in a text document to allow the details to be passed on to the user. Is it possible to script such a procedure or is this something Workgroup Manager can do? Regards P
