Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am using Red Hat Linux version 2.6.9-34
I am looking for a system parameter to set that allows other users than root to issue the chown command.
Standard this is not allowed but i need to override it.
I know on Solaris this is possible. What abaout This version of Linux?
chown is in /usr/bin thus is available to all users. Any user can chown files they own. If you want to allow them to chown files they do not own, then yes, sudo will work.
I think this is true on some Unix system or another but, AFAIK, on Linux you actually can't chown files whether you own them or not, since that's a way to 'give away' files to some poor slob and avoid quota restrictions by saddling him with them.
Also check out the PAM (Pluggable Athentication Modules) facility. And ACLs (Access Control Lists).
Check out these info pages:
The PAM facility allows you to configure the authentication mechanisms which will apply to all kinds of tests. For example, on many systems only members of the wheel group may issue the command su. But why? The answer is "PAM."
The ACL facility allows you to define more fine-grained access controls for resources (such as files) than those which are provided by the usual Unix-style protection mechanisms. You may well find that, with proper use of this facility, you don't need to fiddle with chown anymore. (Windows has a similar facility.)
