Formerly known as ipa_check_consistency and check_ipa_consistency
The tool can be used as a standalone consistency checker as well as a Nagios/Opsview plug-in (check Nagios section below for more info).
The script was originally written and then developed in BASH (until version v1.3.0) and eventually ported to Python in v2.0.0.
It has been tested with multiple FreeIPA 4.2+ deployments across a range of operating systems.
Requirements:
- FreeIPA 4.2+
- Python 2.7+/3.3+
- Python modules listed in requirements.txt
If you spot any problems or have any improvement ideas then feel free to open an issue and I will be glad to look into it for you.
A recommended way of installing the tool is pip install.
Once installed, a command line tool cipa should be available in your system's PATH.
If you do, pip will install new dependencies globally and override existing
packages with potentially incompatible versions. This is particularly important
when installing cipa on a machine running FreeIPA server.
You should either install the package as an unprivileged user with
pip install --user or use a virtual environment.
Please note, in RHEL/CentOS systems you may need to install the following packages:
$ sudo yum install python-devel openldap-devel
Debian/Ubuntu systems may require these packages instead:
$ sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev
The tool is available in PyPI and can be installed using pip:
$ pip install --user checkipaconsistency
$ cipa --help
Run the following command to install required Python modules:
$ git clone https://github.com/peterpakos/checkipaconsistency.git
$ cd checkipaconsistency
$ pip install --user -r requirements.txt
$ ./cipa --help
By default, the tool reads its configuration from
~/.config/checkipaconsistency file (the location can be overridden by setting
environment variable XDG_CONFIG_HOME). If the config file (or directory) does
not exist then it will be automatically created and populated with sample
config upon the next run. Alternatively, you can specify all required options
directly from the command line.

If you experience any problems with the tool, try running it in debug mode:
$ cipa --debug
2017-12-22 20:05:04,494 [main] DEBUG Namespace(binddn=None, bindpw=None, critical=2, debug=True, disable_border=False, disable_header=False, domain=None, hosts=None, log_file=None, nagios_check=None, quiet=False, warning=1)
2017-12-22 20:05:04,494 [main] DEBUG Initialising...
2017-12-22 20:05:04,494 [main] DEBUG Config file not found at /Users/peter/.config/checkipaconsistency
2017-12-22 20:05:04,494 [main] INFO Initial config saved to /Users/peter/.config/checkipaconsistency - PLEASE EDIT IT!
2017-12-22 20:05:04,495 [main] CRITICAL IPA domain not set
For more verbosity use --debug --verbose arguments.
The tool can be easily transformed into a Nagios/Opsview check:
$ pip install checkipaconsistency
$ su - nagios
$ vim ~/.config/checkipaconsistency
$ ln -s `which cipa` /usr/local/nagios/libexec/check_ipa_consistency
Perform all checks using default warning/critical thresholds:
$ /usr/local/nagios/libexec/check_ipa_consistency -n all
OK - 15/15 checks passed
Perform specific check with custom alerting thresholds:
$ /usr/local/nagios/libexec/check_ipa_consistency -n users -w 2 -c3
OK - Active Users
Normally conflicting changes between replicas are resolved automatically (the most recent change takes precedence). However, there are cases where manual intervention is required. If you see LDAP conflicts in the output of this script, you need to find the conflicting entries and decide which of them should be preserved/deleted.
