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.
We noticed that. Several pages of dependencies if one make a yum remove of krb5-workstation. I'm really dont want to try upgrading. Its more like i'm looking for arguments against such a crazy thing.
I would look at it as follows:
- CentOS-4/5 do not have kerberos needed.
- Fedora-10/11 does have the kerberos needed.
- 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.
We have figured it out that far. On platforms like Solaris, ubuntu Fedora and others we have no problem printing. The problem is that we have a lot of software that require both centos 5 and centos 4. Cannot abandon centos for those clients. Also, the print project is a solution offered/pushed to us. Obviously we cannot use it on centos. They (the project leaders) have to choose another solution for centos. That will be the answer to the project leaders.
A last set would be to have a seperate set of kerberos Libraries and statically compile the cups you want against those. Its an ugly hack but works in those cases.
Excellent tip! We completely missed that. Have now compiled and tested this on one client. It works!
Thanks a lot!
Now to the formalities.. My apoligies for kidnapping a thread! A mistake that will not happen again..
