question on multiple CA certs with the same DN




  Sort of a follow-up to my previous message--

  Wanted to make sure CML support a PKI topology currently in use in the
  Federal space...  I'm working on arranging an experiment for this, but
  thought maybe someone might be able to provide me assurance more quickly
  than I can arrange for all the necessary cross-certs to be updated..

  In the FBCA, a "key roll-over" technique is being used; this means that
  CA's will have multiple self-signed certificates with the same
  issuer/subject DN's, but different validity periods and different auth
  subj key ID fields.

  "link certs" (really single-direction cross-certs) are used to tie the
  "old" and "new" certs together.

  All the old, new, and link certs are posted as "caCertificate;binary" in
  the directories, and the CA really comes basically a mesh of certs.


  Some of the problems I've been having with CML seem to be associated with
  the fact that a certificate that was selected as matching a CRL based on
  DN ends up not matching when the CRL's auth Key ID is tested against the
  cert's subject key ID.

  So the question is-- will CML be confused by this arrangement where
  multiple certs exist with the same issuer/subject pair, but different key
  ID's...?

  Thanks & best regards,
