Chapter 108. Verifying permissions of IdM configuration files using Healthcheck


Learn more about how to test Identity Management (IdM) configuration files using the Healthcheck tool.

Prerequisites

  • The Healthcheck tool is only available on RHEL 8.1 or newer systems.

108.1. File permissions Healthcheck tests

The Healthcheck tool tests the ownership and permissions of files installed or configured by Identity Management (IdM).

If you change the ownership or permissions of these files, the tests return a warning in the result section. While this does not necessarily mean that the configuration does not work, it means that the file differs from the default configuration.

You can find the file permissions tests under the ipahealthcheck.ipa.files source of the output of the ipa-healthcheck --list-sources command.

IPAFileNSSDBCheck
This test checks the 389-ds NSS database and the Certificate Authority (CA) database, if relevant. The 389-ds database is located in /etc/dirsrv/slapd-<dashed-REALM> and the CA database is located in /etc/pki/pki-tomcat/alias/.
IPAFileCheck

This test checks the following files:

  • /var/lib/ipa/ra-agent.{key|pem}
  • /var/lib/ipa/certs/httpd.pem
  • /var/lib/ipa/private/httpd.key
  • /etc/httpd/alias/ipasession.key
  • /etc/dirsrv/ds.keytab
  • /etc/ipa/ca.crt
  • /etc/ipa/custodia/server.keys
  • /etc/resolv.conf
  • /etc/hosts

    If PKINIT is enabled, it also tests:

  • /var/lib/ipa/certs/kdc.pem
  • /var/lib/ipa/private/kdc.key

    If DNS is configured, it also tests:

  • /etc/named.keytab
  • /etc/ipa/dnssec/ipa-dnskeysyncd.keytab
TomcatFileCheck

This test checks certain tomcat-specific files:

  • /etc/pki/pki-tomcat/password.conf
  • /var/lib/pki/pki-tomcat/conf/ca/CS.cfg
  • /etc/pki/pki-tomcat/server.xml

108.2. Screening configuration files using Healthcheck

Follow this procedure to run a standalone manual test of an Identity Management (IdM) server’s configuration files using the Healthcheck tool.

The Healthcheck tool includes many tests. Results can be narrowed down by:

  • Including only ownership and permissions tests: --source=ipahealthcheck.ipa.files

Procedure

  1. To run Healthcheck tests on IdM configuration file ownership and permissions, while displaying only warnings, errors and critical issues, enter:

    # ipa-healthcheck --source=ipahealthcheck.ipa.files

A successful test displays empty brackets:

# ipa-healthcheck --source=ipahealthcheck.ipa.files
[]

Failed tests display results similar to the following WARNING:

{
  "source": "ipahealthcheck.ipa.files",
  "check": "IPAFileNSSDBCheck",
  "result": "WARNING",
  "kw": {
    "key": "_etc_dirsrv_slapd-EXAMPLE-TEST_pkcs11.txt_mode",
    "path": "/etc/dirsrv/slapd-EXAMPLE-TEST/pkcs11.txt",
    "type": "mode",
    "expected": "0640",
    "got": "0666",
    "msg": "Permissions of /etc/dirsrv/slapd-EXAMPLE-TEST/pkcs11.txt are 0666 and should be 0640"
  }
}
Note

Run these tests on all IdM servers when trying to find issues.
