Role Based Access Control in RH8.0?

[Bong Chih How]

Dear sir/madam,     Hi all. Just playing with Rh 8.0 recently. I just wonder if RH has Role Based Access Control function like in Solaris? It is basically a utilty to allow one define various role in a system. For example I can define primary administrator (pa) or operator where pa is some role as root but operator can only create user.     Thanks.
