Well, since SELinux and LIDS both provide ACLs, they offer basically the same type of security. I do not believe it's possible or even reasonable to have two ACL systems at the same time. In addition to the problem with complexity, SELinux has licensing issues that make it less desirable. Check here: http://security.linux.com/security/05/03/11/2313226.shtml
