When a deployment gets promoted from CA-less to CA-ful other replicas still have enable_ra=False in default.conf, and do not have the ra-agent key and certificate. Enhance ipa-certupdate to detect when the deployment has become CA-ful; retrieve the ra-agent credential and update default.conf. The rationale for adding this behaviour to ipa-certupdate is that it is already necessary to use this command to update local trust stores with the new CA certificate(s). So by using ipa-certupdate we avoid introducing additional steps for administrators. It is necessary to choose a CA master to use as the ca_host. We use the first server returned by LDAP. A better heuristic might be to choose a master in the same location but this is just left as a comment unless or until the need is proven. Finally, defer the httpd service restart until after the possible update of default.conf so that the IPA API executes with the new configuration. This change also addresses the case of a CA server being removed from the topology, i.e. ipa-certupdate detects when non-CA replicas are pointing at the removed server, and chooses a new ca_host. HOW TO TEST: 1. Install a CA-less server (first server). 2. Install a CA-less replica. 3. Run 'ipa-ca-install' on first server, promoting deployment from CA-less to CA-ful. 4. Run 'ipa-certupdate' on second server. 5. Exceute 'ipa cert-show 5' on second server. Should succeed, because ra-agent credential was retrieved and default.conf updated at step #4.

FreeIPA Server
FreeIPA allows Linux administrators to centrally manage identity, authentication and access control aspects of Linux and UNIX systems by providing simple to install and use command line and web based management tools.
FreeIPA is built on top of well known Open Source components and standard protocols with a very strong focus on ease of management and automation of installation and configuration tasks.
FreeIPA can seamlessly integrate into an Active Directory environment via cross-realm Kerberos trust or user synchronization.
Benefits
FreeIPA:
- Allows all your users to access all the machines with the same credentials and security settings
- Allows users to access personal files transparently from any machine in an authenticated and secure way
- Uses an advanced grouping mechanism to restrict network access to services and files only to specific users
- Allows central management of security mechanisms like passwords, SSH Public Keys, SUDO rules, Keytabs, Access Control Rules
- Enables delegation of selected administrative tasks to other power users
- Integrates into Active Directory environments
Components
The FreeIPA project provides unified installation and management tools for the following components:
- LDAP Server - based on the 389 project
- KDC - based on MIT Kerberos implementation
- PKI based on Dogtag project
- Samba libraries for Active Directory integration
- DNS Server based on BIND and the Bind-DynDB-LDAP plugin
