FreeIPA: CSR Generation and SSL Installation Introduction Status Feature complete, needs testing. Fedora The dogtag packages are now available in Fedora. The required packages should be pulled in as dependencies when ipa-server is installed. This just makes the binaries available for the IPA installer script. The installer creates and configures the necessary dogtag components to stand up a CA. Installing A dogtag CA is installed by default by IPA.

Apr 2, 2014 - To setup SSH for Mac OSX on your jenkins user, refer to this link. Now your master and slave are connected, you need to configure the. How to automatically build your IPA file and push it to a service such as Testflight. How to Setup FreeIPA Server on RHEL 7. In this tutorial I will show you, how to setup FreeIPA Server on RHEL 7 server. FreeIPA is an integrated Identity and Authentication solution for Linux/UNIX networked environments. A FreeIPA server provides centralised authentication, authorisation and account information by storing data about user, groups, hosts and other objects necessary to manage the.

To install using a self-signed CA instead of dogtag pass in the -selfsign argument to ipa-server-install. The CA uses a separate instance of DS that is used only for the CA. This instance is named PKI-IPA. It will install a CA instance into /var/lib/pki-ca.

A copy of the root CA certificate and private key will be put into /root/cacert.p12. A copy of the CA agent certificate will be put into /root/ca-agent.p12. This agent certificate can be imported into a browser and used to administer CS using the web interface (not recommended).

Use a Different CA (COMODO) to sign the IPA CA certificate If you have an existing CA you can use it make the IPA CA a subordinate. This is a three-step process:. Have ipa-server-install generate a Certificate Signing Request (CSR). Take the CSR to your CA and have it signed. Provide the resulting certificate to ipa-server-install to complete the installation Detailed instructions Run ipa-server-install with whatever arguments are appropriate for your environment and include the -externalca flag: # ipa-server-install -external-ca This will generate a CSR in /root/ipa.csr.

This is the file you need to provide to your CA for signing. You will also need to obtain a PEM copy of your CA trust chain. Once you have both of these you can continue the installer: # ipa-server-install -externalcertfile=/root/ipa.crt -externalcafile=/root/existingca.crt The server caches the answers the first time you run the installer so you don't need to answer the questions again the second time. This cache is removed when the installer is run again. The paths to the certificate and CA must be absolute paths.

The dogtag silent installer will fail if they are not. Once the installation is complete you will have the same files as a standalone IPA CA: /root/cacert.p12 and /root/ca-agent.p12. The only difference is that the CA certificate is signed by your external CA in this mode and self-signed in the default mode. Using Certificates From a Different CA (COMODO) If don't you want to use the new IPA CA features at all that is ok but you'll need to take a few extra steps. There are two ways to achieve this:.

Install IPA using the selfsign CA and replace the server certs post-installation. Provide PKCS#12 files to the installer (and still use the selfsign CA, it just won't generate any certs) The step setting enablera to False disables the cert plugin in the XML-RPC interface. Your IPA server will be unable to issue certificates.

Introduction is an open-source security solution for Linux which provides account management and centralized authentication, similar to Microsoft's Active Directory. FreeIPA is built on top of multiple open source projects including the 389 Directory Server, MIT Kerberos, and SSSD. FreeIPA has clients for CentOS 7, Fedora, and Ubuntu 14.04/16.04. These clients make it fairly straightforward to add machines into your IPA domain. Other operating systems can authenticate against FreeIPA using SSSD or LDAP. In this tutorial, we will be configuring a Ubuntu 16.04 machine to authenticate against an existing FreeIPA server. Once your client is configured, you will be able to manage which users and groups of users may log into the machine.

In addition you will be able to set which users may use sudo. Prerequisites To follow this tutorial, you will need:. One CentOS 7 server with the FreeIPA server software installed, which you can set up by following. One Ubuntu 16.04 server set up by following, including a firewall. However, because we will be using FreeIPA to manage users, it's not necessary to manually add a sudo non-root user. You can simply follow this tutorial as root.

The following DNS records set up for your Ubuntu server. You can follow for details on how to add them.

An A record with your server name (e.g. pointing to your client server's IPv4 address. An AAAA record with your server name pointing to your client server's IPv6 address, if you want your server reachable via IPv6. Throughout this tutorial, we'll be using as the example domain for your Ubuntu IPA client, and for your CentOS IPA server (to match the prerequisite tutorial).

Step 1 — Preparing the IPA Client Before we start installing anything, we need to do a few things to make sure your Ubuntu server is ready to run the FreeIPA client. Specifically, we'll set the server hostname, update the system packages, and check that the DNS records from the prerequisites have propagated.

To begin, the hostname of your Ubuntu server will need to match your fully qualified domain name (FQDN) for the FreeIPA client to work correctly. We'll be using as the FQDN throughout this tutorial. If this is a new server, you can set the hostname when you create the server. If you already have a server, you can use the hostname command instead, as below.

Note that you must be root to change the hostname of an existing system because the hostname is a system parameter and cannot be changed by regular users. hostname If you are changing your server's hostname with the hostname command, it is a good idea to also change it manually in the /etc/hostname file as well. nano /etc/hostname There should only be one line in the file with your server's original hostname. /etc/hosts Then save and close the file.

Once the hostname of your server is set correctly, update the package repositories. apt-get update Finally, we need to verify that the DNS names resolve properly. We can use the dig command for this. Dig is installed on Ubuntu by default.

First, use dig to check the A record. dig +short A This should return yourserveripv4.

If you have IPv6 enabled, you can test the AAAA record the same way. dig +short AAAA This should return yourserveripv6. We can also test the reverse lookup. This tests whether we can resolve the hostname from the IP address. dig +short -x yourserveripv4. dig +short -x yourserveripv6 These should both return

Now that the server is prepared, we can install and configure the FreeIPA client package. Step 2 — Installing the FreeIPA Client In Ubuntu 16.04, the FreeIPA client is included in the default repositories.

apt-get install freeipa-client As the installer runs, it may prompt you for the Kerberos realm and Kerberos servers on a screen titled Configuring Kerberos Authentication. The FreeIPA installer will override these settings, but it's best to enter them correctly here as well. The Kerberos realm was configured when you installed the server.

Generally it will be ipa. The Kerberos server and administrative server should be the address of your IPA server. If you followed the prerequisite server tutorial, this will also be ipa. After these prompts, the ipa-client package will install. Next, run the FreeIPA installation command.

This will run a script that guides you through configuring FreeIPA to authenticate against your CentOS FreeIPA server. ipa-client-install -mkhomedir The -mkhomedir flag tells FreeIPA to create home directories for IPA users when they log in to the machine for the first time. If you do not want this behavior, you can omit this flag.

Re: How To Setup Freeipa Services For Mac Free

The installer will first prompt you for the IPA domain. It is set when you configure the server. Installation script prompt User authorized to enroll computers: admin Finally, enter the password for your IPA admin user. This was set during the FreeIPA server configuration.

After you enter the password, the FreeIPA client will configure the system. The last line of output will be Client configuration complete. This indicates a successful install.

Now, we need to verify that our system shows up in the IPA web interface. Step 3 — Verifying Authentication Navigate to your IPA web UI, which is Log in to the web UI with the IPA admin account you used earlier.

You will see the following screen: Navigate to the Hosts tab. You should see your IPA server listed as well as the client you just configured. Click on the entry for your IPA client.

This will take you to an overview of the host. From this screen, you can enter information about the client machine as well as managing groups and roles for the machine. Note: By default, all IPA users may login to all machines within the IPA domain. You can also try logging in to the machine with an IPA user from your local terminal. ssh [email protected] You will log into your machine as an IPA user. You can exit back out of this connection once it's successful. IPA users will have basic access, but sudo is disabled.

In the next step, we'll enable sudo. Step 4 — Enabling and Verifying sudo Rules (Optional) It is not necessary to modify the client configuration files to get enable sudo access; however, if you want to, you must configure sudo rules in the IPA web UI to allow access. FreeIPA allows you to specify which users and user groups may run sudo commands on which machines. It is also possible to limit the commands a user may run with sudo, and which users they may impersonate.

In this tutorial, we will cover adding a simple rule that allows the admin group full sudo access to all machines. Note that the admin group, along with the other groups displayed below, exist by default in FreeIPA. From the IPA web UI, click on Services and then click sudo. A dropdown menu should appear.

In the dropdown menu, click sudo rules, then click add and enter a name for the rule in the Rule name field. Here, we'll use admin because we're allowing sudo for the admin group.

Next, click add and edit. This will bring up the full set of options for the rule. Under Who and User groups click + add.


Select the admins group and click the arrow to move it from Available to Prospective. Then click Add. Under Access this host, select Any host. Under Run Commands, select Any Command.

Under As Whom, select Anyone and Any Group. This is where you could restrict these machines sudo is enabled on, the commands that can be run with sudo, and which users can be impersonated.

Finally, scoll to the top of the page and click Save. Your rule should now be active; however, it may take some time to propogate, and you may have to restart the sshd service for sudo rules to take affect. To do this, you can run systemctl restart sshd.service on the IPA client. Once that's done, let's verify that we do have sudo access on the client machine. From your local machine, try logging in to the client with the IPA admin user.

Re: How To Setup Freeipa Services For Mac Pro

This user is by default in the admins group. ssh [email protected] Once you've logged in, attempt to start an interactive sudo prompt. sudo -i The prompt should now change to [email protected] You can simply type exit to return to the regular prompt. If you are denied sudo access, you may want to reboot the machine and make sure that your sudo rule is configured properly. Conclusion With your machine configured to authenticate against FreeIPA, you can configure user and group access to your system from the IPA web UI or from its command line interface.

FreeIPA has advanced functionality available, but for simpler configurations, you can simply add users and hosts providing a straightforward centralized authentication system. FreeIPA is an extremely versatile authentication tool, and what you will need to do next depends largely on how you intend to use it.
