As I recall (and I can ask Tom when I see him tomorrow), "su" does not support the /usr/adm/sulog like other "su"'s do. It performs auditing, which is implmented in such a way that it can be made untamperable. To find out who is su'ing to root, turn on auditing for the appropriate audit event for all of your users. su will then cut an audit record everytime someone uses it. Each record contains enough information to figure out who done it. -- John F.
