I got perfect answers from both Fraser and you. Thanks a lot.
As I initially thought, a FreeIPA ( or Dogtag with less features....(?)) is
still the best idea.
But our (MS) AD/PKI admins had some doubts, and were convinced you have to
deploy subCA CA certificates to clients.
To conclude:
- it is much simpler for our team to setup FreeIPA CA services as a subCA
also because we don't need to create and secure and offline CA in that case.
Yes, creating a sub-CA of the organisation's existing CA avoid this
duplicate effort. There may be some good reasons to want a separate
root for IDM, but where there is an existing PKI, most organisations
choose to chain IDM into it.
- we don't need to distribute certs to windows clients
That's right.
- the rootCA (AD PKI) can always revoke our subCA when there is a
problem/breach. Correct?
Yes. The usual caveats around CRLs, OCSP etc apply.
Cheers,
Fraser
