Perform the following steps to replace the certificate associated with the original key pair:

  1. Create a CSR file for the server-cert. 
    manage-certificates generate-certificate-signing-request \
  --keystore keystore \
  --keystore-type JKS \
  --keystore-password-file keystore.pin \
  --alias server-cert \
  --use-existing-key-pair \                
  --subject-dn "CN=ldap.example.com,O=Example Corporation,C=US" \
  --output-file server-cert.csr
  2. Submit server-cert.csr to a CA for signing.
  3. Export the server’s private key into server-cert.key. 
    manage-certificates export-private-key \
  --keystore keystore \
  --keystore-password-file keystore.pin \
  --alias server-cert \
  --output-file server-cert.key
  4. Import the certificates obtained from the CA, including the CA-signed server certificate, the root CA certificate, and any intermediate certificates, into keystore.new. 
    manage-certificates import-certificate \
  --keystore keystore.new \
  --keystore-type JKS \
  --keystore-password-file keystore.pin \
  --alias server-cert \
  --private-key-file server-cert.key \
  --certificate-file server-cert.crt \
  --certificate-file intermediate.crt \
  --certificate-file root-ca.crt
