About certificate revocation lists for external CA
Certificate revocation list (CRL) for an external certificate authority (CA) contains a list of digital certificates that the external CA has revoked before the scheduled expiration date and should no longer be trusted.
NetBackup supports PEM and DER formats for CRLs for external CA.
CRLs for all CRL issuers or external CAs are stored in the NetBackup CRL cache that resides on each host.
During secure communication, each NetBackup host verifies the revocation status of the peer host's external certificate with the CRL that is available in the NetBackup CRL cache, based on the ECA_CRL_CHECK configuration option.
See ECA_CRL_CHECK for NetBackup servers and clients.
The NetBackup CRL cache is updated with the required CRLs using one of the following CRL sources:
ECA_CRL_PATH configuration option | A NetBackup configuration option (from See ECA_CRL_PATH_SYNC_HOURS for NetBackup servers and clients. |
CRL distribution point (CDP) | If you have not specified ECA_CRL_PATH, NetBackup downloads the CRLs from the URLs that are specified in the peer host certificate's CDP and caches them in the NetBackup CRL cache. See How CRLs from CDP URLs are used. NetBackup supports downloading CRLs from HTTP and HTTPS URLs that are specified in CDP. |
The NetBackup CRL cache contains only the latest copy of a CRL for each CA (including root and intermediate CAs).
The bpclntcmd -crl_download service updates the CRL cache during host communication in the following scenarios irrespective of the time interval set for the ECA_CRL_PATH_SYNC_HOURS or ECA_CRL_REFRESH_HOURS options:
When CRLs in the CRL cache are expired
If CRLs are available in the CRL source (ECA_CRL_PATH or CDP), but they are missing from the CRL cache
Note:
Once the bpclntcmd -crl_download service updates the CRLs in the CRL cache, it does not download the CRLs for the same CA for the next 15 min even though a valid download scenario has occurred. If you want to update the CRL within 15 min, terminate the bpclntcmd -crl_download service.
