While the error messages may not be causing showstopper issues, they do imply
that something may not work down the road (depending on how the certs you're
issuing are being used).
When the error message states "...when processing requires Active Directory
access", it implies that the CA is configured to publish something to AD
(e.g. user certificates, CRL, CA cert).
Check the CA cert and one of the issued certs to see if any of them have
fields named the following:
- CRL Distribution Point
- Authority Information Access
If any of these contain a non-http:// URL (i.e. ldap:///), this may account
for it.
The other possibility is that the CA is somehow trying to push user certs to
the Active Directory. This isn't supposed to happen unless it's an
Enterprise CA, but just to be sure, look for any additional error messages
that may give further clues as to what particular operations/information are
being attempted by the CA.
