I'm a bit confused with how CRLs and AIAs work. I am on a domain B and I have been tasked with building a Subordinate CA that has an offline Root CA located in Domain A perimeter. These domains are not in the same forest. There is a trust.
Domain A has an offline Root CA and a Subordinate CA. A Subordinate CA in Domain A, B, C, and D will all use Domain A's Root CA.
How should CDPs and AIAs be handled in this situation? Should CDPs and AIAs be published in one location such as a web server in Domain A?
When building my Sub CA in my Domain B, do I enter in CDP and AIA locations pointing to the web server located on Domain A? Or can I leave the default locations (within the Extensions tab) and this will be done automatically?
Should I be hosting my own CRL and AIA?
