Chapter 5. Changing the CA trust flags

The certificate authority (CA) trust flags define for which scenarios Directory Server trusts a CA certificate. For example, you set the flags to trust the certificate for TLS connections to the server and for certificate-based authentication.

You can set the following trust flags on a certificate authority (CA) certificate:

  • C: Trusted CA
  • T: Trusted CA client authentication
  • c: Valid CA
  • P: Trusted peer
  • p: Valid peer
  • u: Private key

You specify the trust flags comma-separated in three categories: TLS, email, object signing

For example, to trust the CA for TLS encryption and certificate-based authentication, set the trust flags to CT,,.

Prerequisites

  • You imported a CA certificate to the network security services (NSS) database.

Procedure

  1. Use the following command to change the trust flags of a CA certificate: 

    # dsconf -D "cn=Directory Manager" ldap://server.example.com security ca-certificate set-trust-flags "Example CA" --flags "trust_flags"

Verification

  • Display all certificates in the NSS database: 

    # certutil -d /etc/dirsrv/slapd-instance_name/ -L
