Hi
My problem is related to clientless authentication for printing. We are evaluating if it's worth the trouble on centos. Uppgrading cups is not a problem That i have already solved. Further research also states that kerberos have to be version 1.6.3. This is a big problem. Neither centos 4 nor centos 5 have the required version of kerberos. Compiling my own compile kerberos is not something i want to do!
Is it worth it or even possible to upgrade kerberos to 1.6.3 or will we most likely break something else with an upgrade?? No rpms are available and i suppose there's a reason for that. There's no problem compiling cups or kerberos on both platforms. I just wanna find out if it is worth the trouble we will get or if it's possible/recommended to do it?!?!.
Upgrading kerberos on CentOS systems is not a trivial task. Kerberos is a basic component for a lot of packages which requires a large dependency chain. I would look at it as follows:
1) CentOS-4/5 do not have kerberos needed. 2) Fedora-10/11 does have the kerberos needed. 3) CentOS-6 might be based off of Fedora-11.
Build your proof of concept project with Fedora-10 with a plan of rebuilding the system after CentOS-6 comes out. Then you have both an immediate win and a long term plan on how to reach a stable product.
Hope that helps.
Best Regards, Thomas

Using Kerberos Authentication CUPS 1.3 adds Kerberos support which allows you to use a Key Distribution Center (KDC) for authentication on your local CUPS server and when printing to a remote authenticated queue. This document describes how to configure CUPS to use Kerberos authentication and provides helpful links to the MIT help pages for configuring Kerberos on your systems and network.
