Disabling certificate management

You can disable or enable dynamic monitoring of certificates on selected computers. To disable or enable dynamic monitoring of certificate management entirely, see Setting certificate configuration.

If you disable dynamic monitoring of certificates, you can update the Active Administrator® database manually at any time by clicking Sync for a selected managed computer.

Managing monitored organizational units

You can monitor organizational units (OUs) to check for computers that are added or removed. If monitoring is enabled, Active Administrator automatically adds newly discovered computers in the monitored OUs to the Certificate Management window. If a computer is removed, it is automatically removed from the Certificate Management window, if computer removal is enabled.

When editing a monitored OU, you can choose to enable/disable monitoring, include/exclude nested OUs, enable/disable automatic removal of computers, or change the credentials used to monitor OUs.

NOTE: To reload the list of OUs, click Refresh. All selections are cleared and any newly added OUs appear in the list.

Viewing certificates

The Certificate Management window displays the certificates for the selected computer, while the Certificate Repository displays all the certificates you added. The heading at the top of the display enumerates the total valid, expiring soon, expired, deleted, and broken certificates. The state of each certificate is indicated by an icon so you can easily see the status of the certificates.

If someone deleted a certificate using native tools, the certificate displays at the bottom of the screen. You easily can restore the deleted certificate from the Active Administrator database or install the certificate on another computer.

Broken certificates also display in a pane at the bottom of the screen. You can attempt to repair the broken certificate or override the broken certificate, which replaces the certificate stored in Active Administrator with the broken certificate. See Managing broken certificates.

The displayed certificates are a reflection of the contents of the Active Administrator® database. The display updates automatically based on the synchronization schedule set in certificate configuration. See Setting certificate configuration.

NOTE: If Certificate Protection is enabled (see Configuring certificate protection), the database and display are not refreshed, but the certificates on the computer are checked against the database for differences. If broken certificates are found, email notifications are sent. If auto-repair is enabled, broken certificates are repaired automatically (see Managing broken certificates).
To filter the list of certificates, start typing in the Filter Certificates by Name box. The display updates as you type.

While viewing certificates for a selected computer, you can group the list of certificates by stores or by the state of the certificate.

To group certificates, click Group by | Store or Group by |State.
To remove the grouping, click Group by | Remove Grouping.
