16.6. Changing the Trust Settings of a CA Certificate
Certificate System subsystems use the CA certificates in their certificate databases to validate
certificates received during an SSL-enabled communication.
It can be necessary to change the trust settings on a CA stored in the certificate database, temporarily
or permanently. For example, if there is a problem with access or compromised certificates, marking
the CA certificate as untrusted prevents entities with certificates signed by that CA from authenticating
to the Certificate System. When the problem is resolved, the CA can be marked as trusted again.
To untrust a CA permanently, consider removing its certificate from the trust database. For
instructions, see
Section 16.5.3, “Deleting Certificates from the Database”
.
