Kerberos Test Server for training purposes

[abohmeed]

Dear all
I am appearing for the RHCE exam next week (wish me luck). While training for the exam, i am supposed to configure the client to log on using an LDAP server that is also using TLS and Kerberos for authentication. Server setup is not included in the exam requirements only the client configuration. So here is my question: Where can i find a guide to install Kerberos on RHEL 6? I need a machine to be my LDAP/Kerberos server to practice client authentication through it. I want the bare minimum configuration, something like a dummy server. This is not a production environment, only training so i need something that's quick and easy using the minimum configuration possible.
One last thing: on the client side, iptables firewall will be enabled by default, so when i try to authenticate using Kerberos, do i need to enable any ports?
Thanks a lot in advance, i really appreciate any help

I think you need to run the system-config-authentication tool. That is a GUI that will make it easy for you to configure LDAP on the client. It should modify /etc/ldap.conf, /etc/openldap/ldap.conf and maybe /etc/nsswitch.conf. It is part of the authconfig-gtk package.

Check out the RHEL 6 Deployment Guide, too.

I don't remember if you need to open ports on the firewall, but if you do, the RHEL 6 firewall tool (system-config-firewall) is pretty robust.

Good luck!
