Certificate Manager Flexibility and Scalability
The Certificate Manager can be deployed in several ways to provide flexibility in
your PKI including support for multiple registration authorities tied to a single CA,
the ability to act as a root or subordinate CA and cloning of a CA to allow CAs with
identical functionality using the same keys and certificates but using different sets
of serial numbers for their issued certificates.
Single CA Supports Multiple Registration Authorities
CMS lets you separate the registration process from the certificate-signing process
with the help of Registration Managers. You can run multiple Registration
Managers remotely, all reporting to a single Certificate Manager, to verify user
identities and process certificate issuance, renewal, and revocation requests. The
remote Registration Managers forward their completed and approved requests to
the Certificate Manager for it to sign and issue the certificate automatically.
The Certificate Manager’s ability to support multiple Registration Managers makes
it more scalable and also adds an extra layer of security for the CA. For example,
you can set a policy that requires all clients to go through a remote Registration
Manager, and then have the remote Registration Manager route all client requests
to the Certificate Manager located inside a firewall.
