Task Remarks
Retrieving the CA
certificate
Required
Obtain the CA certificate and save it locally. For more information, see "Retrieving and
di
splaying a certificate."
Certificate retrieval serves the following purposes:
• Locally store the certificates associated with the local security domain for improved
query efficiency and reduced query count,
• Prepare for certificate verification.
IMPORTANT:
If a local CA certificate already exists, you cannot perform the CA certificate retrieval
operation. This is to avoid possible mismatch between certificates and registration
information resulting from relevant changes. To retrieve the CA certificate, you need to
remove the CA certificate and local certificate first.
Requesting a local
certificate
Required
When requesting a certificate, an entity introduces itself to the CA by providing its
identity information and public key, which will be the major components of the
certificate.
A certificate request can be submitted to a CA in online mode or offline mode.
• In online mode, if the request is granted, the local certificate will be retrieved to the
local system automatically.
• In offline mode, you need to retrieve the local certificate by an out-of-band means.
IMPORTANT:
If a local certificate already exists, you cannot perform the local certificate retrieval
operation. This is to avoid possible mismatch between the local certificate and registration
information resulting from relevant changes. To retrieve a new local certificate, you need
to remove the CA certificate and local certificate first.
Destroying the RSA
key pair
Optional
Destroy the existing RSA key pair and the corresponding local certificate.
If the certificate to be retrieved contains an RSA key pair, you need to destroy the
existing RSA key pair. Otherwise, the retrieving operation will fail.
Retrieving and
displaying a
certificate
Optional
Retrieve an existing certificate and display its information.
IMPORTANT:
Before retrieving a local certificate in online mode, be sure to complete LDAP server
configuration.
Retrieving and
displaying a CRL
Optional
Retrieve a CRL and display its contents.
