Is pathlen:0, e.g.

I would say it should be sufficient for FreeIPA CA for now, given it
allow subordinate CAs. However, I am still CCing Fraser and Honza for
reference, in case there would be some limitation in Dogtag/our CA
that would limit use of the basicConstraints extension.
I'm not aware of any.
Yes, currently it is sufficient. When FreeIPA has sub-CAs
capability, a pathLenConstraint of zero will prevent the creation of
Martin, Jan, this is a situation I had not considered. I propose
that we should detect pathLenConstraint and error out if sub-CAs
creation is attempted at a depth that cannot be valid. If you agree
I will add to design document.
I agree. Please also add a ticket for this part. The check can be IMO
added to FreeIPA 4.2.1, it is not critical for 4.2 GA.
I believe there would be other things to check as well, e.g.
directoryName name constraints.
Note that this basiConstrain would surely prevent you from using the
but this is OK with you, I assume. BTW, Fraser, we should record a
properly watch for the pathlen limitation and have nice error
it when admin attempts to use Sub-CAs.
Final note, there is a related ticket:
