Removing trust between a host and a master server
A NetBackup host can trust multiple Certificate Authorities (master servers) at any time. For various reasons, it may be necessary for a NetBackup host to remove trust from a master server that previously had been trusted.
For example, if a NetBackup client is moved from one master server to another, it is advisable to remove trust from the first master server. Security best practices suggest trusting the fewest entities required to function correctly. Also, if a NetBackup host no longer needs to communicate with hosts from a specific NetBackup domain, remove the CA certificate for that master from the trust store of the host.
Note:
Removing a CA certificate does not remove the host ID-based or host name-based certificates that the host may have obtained from that CA. The nbcertcmd -listCertDetails continues to show the host ID-based certificate.
When the CA certificate is removed from a host, the host ID-based certificate issued by that CA will not automatically renew because the host no longer trusts the CA. The host ID-based certificate eventually expires.
Removing trust between a host and a master server
- The administrator of the non-master host runs the following command on the host to determine the CA certificate fingerprint of the master server:
nbcertcmd -listCACertDetails
In this example output, the host has certificates from two master servers:
nbcertcmd -listCACertDetails Subject Name : /CN=nbatd/OU=root@master1.abc.com/O=vx Start Date : Aug 23 14:16:44 2016 GMT Expiry Date : Aug 18 15:31:44 2036 GMT SHA1 Fingerprint : 7B:0C:00:32:96:20:36:52:92:E8:62:F3:56: 74:8B:E3:2E:4F:22:4C Subject Name : /CN=nbatd/OU=root@master2.xyz.com/O=vx Start Date : Aug 25 12:09:55 2016 GMT Expiry Date : Aug 20 13:24:55 2036 GMT SHA1 Fingerprint : 7A:C7:6E:68:71:6B:82:FD:7E:80:FC:47:F6: 8D:B2:E1:40:69:9C:8C
- The administrator wants to remove trust to the second master server and runs the following command on the host:
nbcertcmd -removeCACertificate - fingerprint 7A:C7:6E:68:71: 6B:82:FD:7E:80:FC:47:F6:8D:B2:E1:40:69:9C:8C
Include the entire fingerprint, including the colons.
- The NetBackup Administration Console on the master server displays the certificate state as Active. However, that certificate does not automatically renew and eventually expires. The NetBackup administrator should revoke the certificate of the host if the host is no longer going to be part of the NetBackup domain.
