A dedicated page about how to install CA certificates might be needed, or the existing one be updated
@waananen said that the new CA certs will not be hosted on the NorduGRID repo for ARC7 so it would be good to have a summary somewhere. I report some discussion from the Devs chat:
The IGTF certs will not be part of the ARC7 repos. My suggestion is to fetch them from IGTF or EGI. It made sense (sort of) to include them in the NorduGrid repo many years ago, but I don't think it is the right thing to do today. I would suggest that sites with many hosts should mirror one of the IGTF distribution points and install from the local mirror.
I also think that if we're going for a "normal" certificate setup we might need some info about those as well.
