The following describes the impact on Certification Authority operations when one of the Certification Authority certificates of a Certification Authority is revoked.
This case may also occur as planned, for example, when a previous certification authority hierarchy is to be decommissioned.
Continue reading „Welchen Einfluss hat der Widerruf eines Zertifizierungsstellen-Zertifikats auf die Zertifizierungsstelle?“The following describes the effects on certification authority operation if the revocation information for one of the certification authority's certificates cannot be retrieved.
This case may also occur as planned, for example, when a previous certification authority hierarchy is to be decommissioned.
Continue reading „Welchen Einfluss haben fehlerhafte Sperrinformationen eines Zertifizierungsstellen-Zertifikats auf die Zertifizierungsstelle?“The following describes the impact on certification authority operations if one of the root certification authority certificates from which one of the certification authority certificates is derived has its trust status revoked, or never had it.
This case may also occur as planned, for example, when a previous certification authority hierarchy is to be decommissioned.

The following is a description of what configuration settings are necessary for a certificate hierarchy based on Active Directory Certificate Services to be compliant with the "Common PKI" standard.
Continue reading „Beschreibung der notwendigen Konfigurationseinstellungen für das „Common PKI“ Zertifikatprofil“In the default configuration, Certificate Authority Web Enrollment (CAWE) accepts only unencrypted connections via HTTP. It is recommended that the CAWE be configured for HTTP over TLS (HTTPS) to make network traffic interception more difficult. Instructions are provided below.

If the user logs in via username and password instead, he or she will not have access to the requested resources.
Originally intended for access to file servers, however, AMA can also be used (with some restrictions) for administrative logon. Thus, for example, it would be conceivable for a user to be unprivileged when logging in with a username and password, and to have administrative rights when logging in with a certificate.

Signing in with a security device isn't supported for your account. For more info, contact your administrator.Continue reading „Die Anmeldung via Smartcard schlägt fehl mit Fehlermeldung „Signing in with a security device isn’t supported for your account.““
When working with Certificate Enrollment Web Services and manually entering certificate enrollment policies on client computers, one encounters the phenomenon that there is no way to edit or delete them in the Certificate Management Console.
Continue reading „Löschen einer manuell konfigurierten Zertifikatbeantragungs-Richtlinie (Enrollment Policy)“The following describes the process that runs in the background when certificates are requested manually or automatically in order to achieve the highest possible level of automation.
Continue reading „Grundlagen manuelle und automatische Zertifikatbeantragung über Lightweight Directory Access Protocol (LDAP) und Remote Procedure Call / Distributed Common Object Model (RPC/DCOM) mit dem MS-WCCE Protokoll“By default, all domain members automatically replicate the Public Key Services object he Active Directory forest through the autoenrollment process. The triggers for this are:
If you do not want to wait for the autoenrollment to be triggered automatically, you can start it manually. The different ways to run the autoenrollment process are described below.
Continue reading „Manuelles Ausführen des Autoenrollment Prozesses“Authentication Mechanism Assurance (AMA) provides the ability to tie membership in a security group to enrollment with a smart card certificate containing a specific Object Identifier (OID).
If the user does not log in with the smartcard certificate, but with user name and password, he is also not a member of the security group.
The following describes how to establish the connection between the certificate and the security group.
