Replacing Win Servers with Redhat / Centos
I've recently rejoined the company after being away working as a consultant somewhere else. This other company I was working for had a majority Novell / SuSE layout with Zenworks, Groupwise and eDirectory. It was great, I've always tinkered with nix and have had a dual boot of various flavours on my home PC but have never seen it in use in the enterprise.
So anyway, I've come back to this relatively small company and I'm seeing us plow all this money into MS Licenses and not really getting a return for the costs.
It's a simple setup: 3 Win2k servers. The first is primarily IIS, the second is MSSQL and the third is our file server. We have an AD domain and that's about it. Our email is hosted off site on an Exchange hosted server platform.
My question is, if I were to try and convince my boss that OS is the way to go to save some money (we can't afford to pay one of our suppliers at the moment) how would I do it? I've installed VMWare Server on one of the servers here and have CentOS running and I'm thinking of demonstrating a mail server initially. The only thing is that it has to be compatible with Outlook 2003, easy to administer and robust to handle the accounts of 300+ people.
I'm also considering an alternative to AD but only having exposure to eDirectory I need some suggestions on where to look. Again, ease of use is paramount.
Thanks for any advice.
