[Pki-users] Dogtag Installation on FC6

Hi I am new to the Dogtag Certificate system. I have to install the dogtag certificate system on fedora core 6. I would appreciate help from pki-users who have successfully installed and are runing dogtag certificate system on linux. I read the explanantion on dogtag on http://pki.fedoraproject.org/wiki/PKI_Main_Page yet I have some questions before starting the installation. Following are the questions: 1. Do I have to install and run Apache service on the system on which I am going to implement dogtag? 2. I am confused about the configuration of all the PKI subsystems like CA,RA,DRM...etc. In the http://pki.fedoraproject.org/wiki/PKI_Main_Page the configuration of all subsyems is given but I dont understand from where do I get the configuration URL for each subsystem. 3. I have to integrate the setup with Checkpoint, so need steps on the integration. I would appreciate if someone who has implemented dogtag would provide me easy steps to install dogtag on fedora core 6. Thanks & Regards, Rashmi
