Description

Installation testing.

Setup

  1. Make sure /etc/hosts is sane. This means that your host will be listed on a separate line with its IP address with the FQDN listed first, this is necessary to avoid chicken/egg issues when the DNS is installed as name resolution for the public host name is needed to start the DNS itself (to init krb credentials). In particular the hostname SHOULD not appear in either the IPv4 or IPv6 localhost lines.
  2. If you have an existing AD server in your network, choose a different name for the IPA server realm name. Clients that use DNS autodiscovery to find the KDC to use may get confused and try to authenticate to the AD KDC.

How to test

Installation

First, install the FreeIPA server package:

# yum install freeipa-server

Without DNS

For a fully-interactive install run:

# ipa-server-install

You can optionally provide all options on the command-line:

# ipa-server-install -a secret123 -p 123Secret --domain=ipa.example.org --realm=IPA.EXAMPLE.ORG -U

With DNS

# yum install bind bind-dyndb-ldap
# ipa-server-install --setup-dns

Or with all options on the command-line:

# ipa-server-install -a secret123 -p 123Secret --domain=ipa.example.org --realm=IPA.EXAMPLE.ORG --setup-dns --forwarder=<forwarder IP> -U

Substitute you existing DNS server's IP for <forwarder IP>, or pass --no-forwarders.

Verify the basics

Ideally each of these installation steps will conclude with no errors and a running set of IPA services.

To briefly test the installation:

# kinit admin  # (the password is the admin password, or the password from -a)

Show our own user entry:

# ipa user-show admin

And make sure nss can see us too:

# id admin
# getent passwd admin

Verify Services

We install a number of SSL certificates that should be automatically managed by certmonger:

# ipa-getcert list

There should be 3 certificates, all in MONITORING status. The certificates should be in the following NSS databases:

* /etc/httpd/alias
* /etc/dirsrv/slapd-PKI-IPA
* /etc/dirsrv/slapd-IPA-EXAMPLE-ORG

Now, check the service principals:

# kinit admin
# ipa service-find

There should be 2 services: ldap and HTTP for your FreeIPA server. If you installed DNS, there should be a DNS service as well.

Verify DNS

Verify these only if you installed with a DNS server.

# dig server.ipa.example.org.

Look for a line like this in the output:

server.ipa.example.org.      86400   IN      A       192.168.0.1
# host server.ipa.example.org
server.ipa.example.org has address 192.168.0.1
# ipa dns-resolve server.ipa.example.org
---------------------------
Found 'server.ipa.example.org.'
---------------------------
# ipa host-show server.ipa.example.org
  Host name: server.ipa.example.org
  Principal name: host/server.ipa.example.org@IPA.EXAMPLE.ORG
  Keytab: True
  Managed by: server.ipa.example.org

Client testing

Add a client

If you have more than two machines, install a client of the replica. If you have installed DNS, edit /etc/resolv.conf and add the IPA server as a nameserver.

# yum install freeipa-client
# ipa-client-install

Or with all options on the command-line.

# yum install freeipa-client
# ipa-client-install --domain=ipa.example.org --server=server.ipa.example.org -p admin -w secret123 -U

Verify that nss can see us:

# id admin
# getent passwd admin

With the Package-x-generic-16.pngfreeipa-admintools package, you can test installation using the ipa command:

# yum install freeipa-admintools
# kinit admin
# ipa user-show admin

Remove a client

When you are done with a client, you can uninstall it:

# ipa-client-install --uninstall

The uninstallation should complete with no errors. To verify that uninstallation was successful, install the client again.

Uninstallation

FreeIPA provides a way to unininstall the configured services and it does its best to return the system to its previous state. To run the uninstaller execute:

# ipa-server-install --uninstall -U

Verify uninstallation

Un-installation is intended for developers. It is a best-as-we-can restoration of files primarily to prepare the server to be re-installed.

To verify that the server is in a state where it can be re-installed re-run ipa-server-install:

# ipa-server-install

If something failed in the un-installation you would get an error message that the server is already installed/configured.

Expected Results

All the test steps should end with the specified results.
