Overview

PKI CA can be cloned into a separate instance with a separate database. If cloning is done on the same machine (for testing) the clone instance and database need to run on different ports.

This document assumes that the CA instance to be cloned has been created.

Creating DS Instance

Install a DS instance for the CA clone.

If SSL is enabled on DS master, the DS clone must be configured with SSL too. Make sure the DS master and clone trust each other's certificates.

Exporting CA System Certificates

PKI 10.3 or newer

PKI 10.3 provides a tool to export only the necessary certificates for cloning. To export the CA system certificates (including the certificate chain) into a PKCS #12 file:

$ pki-server ca-clone-prepare --pkcs12-file ca-certs.p12 --pkcs12-password Secret.123

If necessary, third-party certificates (e.g. other trust anchors) can be added into the same PKCS #12 file with the following command:

$ pki -d /var/lib/pki/pki-tomcat/alias pkcs12-cert-add <nickname> --pkcs12-file ca-certs.p12 --pkcs12-password Secret.123

PKI 10.2 or older

Copy the NSS database password into a file:

$ grep "internal=" /var/lib/pki/pki-tomcat/conf/password.conf | awk -F= '{print $2}' > internal.txt

Export all system certificates in master into a PKCS #12 file:

$ PKCS12Export -debug \
 -d /var/lib/pki/pki-tomcat/alias \
 -p internal.txt \
 -o ca-certs.p12 \
 -w ~/.dogtag/pki-tomcat/ca/pkcs12_password.conf

Transfer the file to the clone.

PKI 9.0 or older

Prepare password files:

$ echo Secret.123 > password.txt
$ grep "internal=" /var/lib/pki-ca/conf/password.conf | awk -F= '{print $2}' > internal.txt

Export all system certificates in master into a PKCS #12 file:

$ PKCS12Export -debug \
 -d /var/lib/pki-ca/alias \
 -p internal.txt \
 -o ca-certs.p12 \
 -w password.txt

Verification

Make sure the PKCS #12 file contains at least the following CA system certificates:

$ pki pkcs12-cert-find --pkcs12-file ca-certs.p12 --pkcs12-password Secret.123

If third-party certificates were added, it should appear above as well.

Installing CA Clone

Transfer the PKCS #12 file to the clone. Set the appropriate SELinux contexts for the p12 file

semanage fcontext -a -t pki_tomcat_cert_t /tmp/ca-certs.p12
restorecon -R -v /tmp/ca-certs.p12

Then prepare a deployment configuration file (e.g. ca-clone.cfg):

[CA]
pki_admin_email=caadmin@example.com
pki_admin_name=caadmin
pki_admin_nickname=caadmin
pki_admin_password=Secret.123
pki_admin_uid=caadmin

pki_client_database_password=Secret.123
pki_client_database_purge=False
pki_client_pkcs12_password=Secret.123

pki_ds_base_dn=dc=ca,dc=example,dc=com
pki_ds_database=ca
pki_ds_password=Secret.123

pki_security_domain_hostname=master.example.com
pki_security_domain_https_port=8443
pki_security_domain_user=caadmin
pki_security_domain_password=Secret.123

pki_clone=True
pki_clone_replicate_schema=True
pki_clone_uri=https://master.example.com:8443

pki_clone_pkcs12_path=/tmp/ca-certs.p12
pki_clone_pkcs12_password=Secret.123

If necessary, specify the certificate nicknames in the following parameters to match the nicknames in the PKCS #12 file:

pki_ca_signing_nickname=ca_signing
pki_ocsp_signing_nickname=ca_ocsp_signing
pki_audit_signing_nickname=ca_audit_signing
pki_ssl_server_nickname=sslserver
pki_subsystem_nickname=subsystem

To begin the installation, execute the following command:

$ pkispawn -v -f ca-clone.cfg -s CA

Verification

Verify certificates

The certificates should have the same nicknames and trust flags as in the master:

$ certutil -L -d /var/lib/pki/pki-tomcat/alias

Certificate Nickname                                         Trust Attributes
                                                             SSL,S/MIME,JAR/XPI

ca_signing                                                   CTu,Cu,Cu
ca_ocsp_signing                                              u,u,u
sslserver                                                    u,u,u
subsystem                                                    u,u,u
ca_audit_signing                                             u,u,Pu

Verify keys

The keys should have the same IDs as in the master except for the SSL server key:

$ sed -n "/^internal=/ s/^[^=]*=// p" < /var/lib/pki/pki-tomcat/conf/password.conf > internal.txt
$ certutil -K -d /var/lib/pki/pki-tomcat/alias -f internal.txt
