Information
Public key infrastructure (PKI) certificates are certificates with visibility external to organizational systems and certificates related to the internal operations of systems, such as application-specific time services. In cryptographic systems with a hierarchical structure, a trust anchor is an authoritative source (i.e., a certificate authority) for which trust is assumed and not derived. A root certificate for a PKI system is an example of a trust anchor. A trust store or certificate store maintains a list of trusted root certificates.
Solution
Edit the MongoDB configuration file (default location /etc/mongod.conf) and add a key named "net.tls.CAFile" to configure the certificate trust.
Example shown below:
net:
tls:
mode: requireTLS
certificateKeyFile: /etc/ssl/mongodb.pem
CAFile: /etc/ssl/caToValidateClientCertificates.pem
ocsp:
enabled: true
