Hi:

Unless you (or someone) is root, 'su' prompts the user for a password. This password must be supplied from the terminal, and ALL attempts to use 'su' (successful or not) are logged in /var/adm/sulog.

the only way I can think of is using sudo that will let you define who can use su without - with root privilege except su root(=> no passwd required) and perhaps changing the perms on su if not enough
