IPAv2_beta#

__NOTOC__

Main Highlights of the Beta 1#

  • This beta is the first attempt to show all planned capabilities of the upcoming release.

  • For the first time the new UI is mostly operational and can be used to perform management of the system.

  • Some areas are still very rough and we will appreciate your help with those.

Focus of the Beta Testing#

  • Please take a moment and look at the new Web UI. Any feedback about the general approaches, work flows, and usability is appreciated. It is still very rough but one can hopefully get a good understanding of how we plan the final UI to function and look like.

  • Replication management was significantly improved. Testing of multi replica configurations should be easier.

  • We are looking for a feedback about the DNS integration and networking issues you find in your environment configuring and using IPA with the embedded DNS enabled.

Significant Changes Since Alpha 5#

  • FreeIPA has changed its license to GPLv3+

  • Having IPA manage the reverse zone is optional.

  • The access control subsystem was re-written to be more understandable. For details see Permissions page

  • Support for SUDO rules

  • There is now a distinction between replicas and their replication agreements in the ipa-replica-manage command. It is now much easier to manage the replication topology.

  • Renaming entries is easier with the –rename option of the mod commands.

  • Fix special character handling in passwords, ensure that passwords are not logged.

  • Certificates can be saved as PEM files in service-show and host-show commands.

  • All IPA services are now started/stopped using the ipactl command. This gives us better control over the start/stop order during reboot/shutdown.

  • Set up ntpd first so the time is sane.

  • Better multi-valued value handle with –setattr and –addattr.

  • Add support for both RFC2307 and RFC2307bis to migration.

  • UID ranges were reduced by default from 1M to 200k.

  • Add ability to add/remove DNS records when adding/removing a host entry.

  • A number of i18n issues have been addressed.

  • Updated a lot of man pages.

What is not Complete#

  • We are still using older version of the Dogtag. New version of the Dogtag Certificate System will be based on tomcat6 and is forthcoming.

  • We plan to take advantage of Kerberos 1.9 that was released today but we have not finished the integration effort yet.

Known Issues#

  • IPV6 works in the installer but not the server itself

  • Make sure you machine can properly resolve its name before installing the server. Edit /etc/hosts to remove host name from the localhost and localhost6 lines if needed.

  • The UI is still rough in places Use the following query: Open UI tickets to see the tickets currently open against UI.

  • Dogtag does not work out-of-the-box on Fedora 14. To fix it for for the time being run:

`` # ln -s /usr/share/java/xalan-j2-serializer.jar /usr/share/tomcat5/common/lib/xalan-j2-serializer.jar``

  • Instead of dogtag on F14 you can also try the self-signed CA which is similar to the CA that was provided in IPA v1. This was designed for testing and development and not recommended for deployment.

  • Make sure you enable updates-testing repository on your fedora machine.

Package Requirements#

The dogtag CA is an rpm dependency in. It will be configured by default when installing IPA. To not configure dogtag pass the --selfsign flag to ipa-server-install.

Command Line#

One of the most visible changes is in the IPA command-line programs. Rather than having a series of discrete commands for every function as we had in v1 there is now a single command that takes as the first argument the action you want to take.

For example, adding a user in v1:

% ipa-adduser --first=Jim --last=Example jexample

In v2:

% ipa user-add --first=Jim --last=Example jexample

For a list of topics: ipa help topics

For a full list of available commands: ipa help commands

We have tried to retain at least parity with the v1 commands, let us know how we’ve done (and where we can improve).

In alpha 3 we added a man page for the ipa command.

Clients#

The client installer (ipa-client-install) by default configures the client machine to use SSSD. If you prefer using nss_ldap/pam instead pass the client installer the –no-sssd option.

Replication#

As in v1 all replicas should be created from the initial master. In theory it should be possible to create a clone from a clone when using dogtag as the CA but some problems have been reported when doing this. So it is recommended that all replicas be created from the initial IPA server using ipa-replica-prepare as was required in IPA v1.

If you re-install IPA on a replica machine be sure to delete the host entry from the primary master (ipa host-del replica.example.com) before performing the re-install. You will need to remove the old LDAP replication agreement as well: ipa-replica-manage del --force replica.example.com. If you don’t then the re-installation will fail with errors about certificate already being present in some entries.

CA#

It is currently not possible to install the CA post IPA server installation.

If installing v2 on a machine that was previously installed with IPA v1 and you are not configuring a dogtag CA your serial number file, /var/lib/ipa/ca_serialno, will be upgraded to the v2 format.

Migration#

It is not possible to upgrade an IPA v1 server to an IPA v2 server, too much has changed internally. We have provided a migration mechanism to migrate users and groups from an LDAP server (so this will aid in migration from other identity products as well) to IPA v2.

To perform a migration, install IPA v2 on a clean machine. Once it is installed and working you can migrate users and groups using the migrate-ds command (ipa migrate-ds –help to see options).

Sample usage from a default 389-ds installation:

% ipa migrate-ds`ldap://ldap.example.com <ldap://ldap.example.com>`__

Migration from an IPA v1 server:

% ipa migrate-ds --user-container=cn=users,cn=accounts --group-container=cn=groups,cn=accounts`ldap://ipa.example.com <ldap://ipa.example.com>`__

The output will be the list of users and groups that migrated and those that did not.

It is not currently possible to migrate ONLY users or ONLY groups. It must migrate both. If either no users or no groups is present on the server being migrated from an Entry Not Found will be displayed and the migration will stop before migrating anything.

Documentation#

We are still in the process of writing documentation for the IPA v2. The current progress can be followed at http://freeipa.org/page/IPAv2_development_status#Documentation

Feedback#

The UI and command-line commands use the same underlying plug-ins for functionality. The UI pages are generated on-the-fly using some additional meta-data. This should improve our code maintainability but we also want to create a system that works for you. Any feedback on how this helps/hurts getting your job done would be greatly appreciated.

Also keep in mind that the UI isn’t quite done yet, so be gentle :-)

Bugs#

If you find any problems then please file a ticket in the fre iPA track https://fedorahosted.org/freeipa/ or open a bug against the freeIPA product at the https://bugzilla.redhat.com/

Work Continues#

Our primary focus in the upcoming months will be bringing project to a production quality.
