Tools for managing user access rights?

Dear Informixers, I'm hoping that someone can suggest appropriate tools for managing user access rights in Informix database. I need to maintain security info on field level, and be able to clone user rights based on existing user. Thanks, Andrej Falout #------------------------------------------------------------------------ globals "std_disclaimer.4gl" case author when "John McNally" return "Informix Unleashed", "To develop with 4GL, developer does not have to be an expert programmer" when "Norman Fischer" return "Wired 7.01", "Real technology behind all our technologies is language" when "Pablo Picasso" return NULL, "Computers are useless.
