Well, ok then. Btw you're reading guide for 2.4.x (and you have 2.3.x).
Anyway. Yes, 'Admin' entry != Manager entry. It's probably been added
later by 3rd application, or using % slapadd; or % slapmod;
It's example how to grant permissions to attributes.

This is not Windows. This is world of GNU/Linux. I'm just surprised by
assumption (usually employer's vision) you have to know some
distribution inside and out to be able to administer it. It's GNU/Linux
and it doesn't matter if it's called CentOS, Fedora, Bubuntu, Gentoo or
what not.
I'm not going to google for you, sorry. If there is no specific how-to
for CentOS, which I almost fail to believe, then improvise. Read how-to
for other distro and put pieces together. I presume you know how to
install packages in CentOS, don't you? You should be able to handle the
rest. I can imagine only location of files and text editor used will differ.

I've just described you whole process. What exactly isn't clear?
btw Why don't you use some 3rd application like eg. Apache's Directory
studio? I'm pretty sure I'd make things easier (and faster) for you.
