The CMA system requires a CRL for each CA or sub-CA in the certificate
chain. The CMA system also requires that you upload a new CRL at regular
intervals. This interval can be as short as a few days in higher security
environments or a few months in environments with lower security
requirements.
To upload a certificate revocation list
1 Go to Admin > Management and Security > Certificate Management
and click Upload Certificate Revocation List.
2 In the Select file dialog box, browse to the location of the CRL that you
obtained from the CA and select the file.
3 Click Open.
Delete a Certificate
You can delete certificates from the CMA system, but the CMA system
prevents you from deleting any certificate that breaks the identity certificate’s
chain of trust. To delete these certificates, new CA certificates must be installed
and the identity certificate must be replaced.
To delete a certificate
1 Admin > Management and Security > Certificate Management.
The Certificate Management page displays the list of currently available
certificates.
2 Select the certificate to be deleted and click Delete Certificate.
A warning appears stating that changes made to the certificates will
require a system restart to take effect.
3 Click Yes to continue.
IMPORTANT
If an administrator does not upload a new CRL by the CRL Next Update date, the
system will become unresponsive. Recovering from this situation requires
reinstalling from the recovery disk, manually reconfiguring of identity and root
certificates, and restoring the system from a system backup
Caution
Removing certificates requires a system restart, which terminates all active
conferences.
When you remove a certificate, the change is made to the certificate store
immediately, but the system can’t implement the change until it restarts and reads
the changed certificate store.
