Viewing the certificate authority database revocation list table

By default, the certification authority stores all revocation lists that have not yet expired in the certification authority database.

Under certain circumstances, e.g. due to a misconfigured script, a large number of blacklists are stored in the database in this way, which can lead to a corresponding growth of the database (e.g. if large blacklists are recreated very often).

Manual publishing of a certificate revocation list (CRL) to Active Directory fails with error 0x8007202b (WIN32: 8235 ERROR_DS_REFERRAL)

  • An offline root certificate authority has been installed. The server on which the certificate authority is installed is not a domain member.
  • This is configured for Active Directory blacklist publications.
  • The blacklists are uploaded to the Active Directory using certutil -dspublish.
  • The operation fails with the following error message:
certutil -dspublish "ADCS Labor Root CA.crl"

Requesting a certificate fails with the error message "A valid certification authority (CA) configured to issue certificates based on this template cannot be located, or the CA does not support this operation, or the CA is not trusted."

Assume the following scenario:

  • You try to apply for a certificate from an Active Directory-integrated certification authority (Enterprise Certification Authority).
  • To do this, use the Microsoft Management Console (MMC), either for the logged-in user (certmgr.msc) or for the computer (certlm.msc).
  • However, the desired certificate template is not displayed for selection, even though it has been correctly published on the certification authority.
  • The logged-in user (or computer) also has the necessary permissions to request certificates from the certificate template in question (enroll).
  • In the list of available certificate templates within the MMC, all certificate templates are displayed. At the desired certificate template is written:
A valid certification authority (CA) configured to issue certificates based on this template cannot be located, or the CA does not support this operation, or the CA is not trusted.
