Chapter 9. Verifying system certificates using IdM Healthcheck
Learn more about identifying issues with system certificates in Identity Management (IdM) by using the Healthcheck tool.
For details, see Healthcheck in IdM.
Prerequisites
- The Healthcheck tool is only available on RHEL 8.1 or newer.
9.1. System certificates Healthcheck tests
The Healthcheck tool includes several tests for verifying system (DogTag) certificates.
To see all tests, run the ipa-healthcheck with the --list-sources option:
# ipa-healthcheck --list-sources
You can find all tests under the ipahealthcheck.dogtag.ca source:
- DogtagCertsConfigCheck
This test compares the CA (Certificate Authority) certificates in its NSS database to the same values stored in
CS.cfg. If they do not match, the CA fails to start.Specifically, it checks:
-
auditSigningCert cert-pki-caagainstca.audit_signing.cert -
ocspSigningCert cert-pki-caagainstca.ocsp_signing.cert -
caSigningCert cert-pki-caagainstca.signing.cert -
subsystemCert cert-pki-caagainstca.subsystem.cert -
Server-Cert cert-pki-caagainstca.sslserver.cert
If Key Recovery Authority (KRA) is installed:
-
transportCert cert-pki-kraagainstca.connector.KRA.transportCert
-
- DogtagCertsConnectivityCheck
This test verifies connectivity. This test is equivalent to the
ipa cert-show 1command which checks:- The PKI proxy configuration in Apache
- IdM being able to find a CA
- The RA agent client certificate
- Correctness of CA replies to requests
Note that the test checks a certificate with serial #1 because you want to verify that a
cert-showcan be executed and get back an expected result from CA (either the certificate or a not found).
Run these tests on all IdM servers when trying to find an issue.
9.2. Screening system certificates using Healthcheck
Follow this procedure to run a standalone manual test of Identity Management (IdM) certificates using the Healthcheck tool.
Since, the Healthcheck tool includes many tests, you can narrow the results by including only DogTag tests: --source=ipahealthcheck.dogtag.ca
Procedure
To run Healthcheck restricted to DogTag certificates, enter:
# ipa-healthcheck --source=ipahealthcheck.dogtag.ca
An example of a successful test:
{
"source: ipahealthcheck.dogtag.ca",
"check: DogtagCertsConfigCheck",
"result: SUCCESS",
"uuid: 9b366200-9ec8-4bd9-bb5e-9a280c803a9c",
"when: 20191008135826Z",
"duration: 0.252280",
"kw:" {
"key": "Server-Cert cert-pki-ca",
"configfile": "/var/lib/pki/pki-tomcat/conf/ca/CS.cfg"
}
}An example of a failed test:
{
"source: ipahealthcheck.dogtag.ca",
"check: DogtagCertsConfigCheck",
"result: CRITICAL",
"uuid: 59d66200-1447-4b3b-be01-89810c803a98",
"when: 20191008135912Z",
"duration: 0.002022",
"kw:" {
"exception": "NSDB /etc/pki/pki-tomcat/alias not initialized",
}
