Releases/4.8.0

Release date Released 2019-07-03

The FreeIPA team would like to announce FreeIPA 4.8.0 release!

It can be downloaded from http://www.freeipa.org/page/Downloads. Builds for Fedora 30 will be available in the official COPR repository.

Highlights in 4.8.0

Enhancements

FreeIPA 4.8.0 is a major release. Below is the list of noticeable changes between FreeIPA 4.7 and 4.8.0:

  • Removal or deprecation of weak ciphers

Following a general effort to harden FreeIPA deployments, FreeIPA 4.8.0 removes default support for weak ciphers. 3DES and RC4 ciphers are not accessible for use in Kerberos anymore, and, in addition, Camelia ciphers are not accessible when FreeIPA is deployed in FIPS mode. The only permitted ciphers are the AES family (called aes, which is the combination of: aes256-cts-hmac-sha1-96, aes128-cts-hmac-sha1-96, aes256-cts-hmac-sha384-192, and aes128-cts-hmac-sha256-128).

DES, RC4, and Camellia are not permitted in FIPS mode by the underlying system crypto libraries. While 3DES is permitted, the KDF used for it in Kerberos V protocol is not, and Microsoft doesn't implement 3DES anyway.


  • 3999: [RFE] Fix and Document how to set up Samba File Server with IPA

FreeIPA 4.8.0 introduces a tool to configure Samba file server on IPA client. The tool, "ipa-client-samba" performs Samba configuration and creates all required services on IPA side. Both the client side and the server side (IPA master) require FreeIPA 4.8.0 due to multiple changes introduced. Please see domain controller and domain member design documents for more details.


  • 4440: Add support for bounce_url to /ipa/ui/reset_password.html

The /ipa/ui/reset_password.html page accepts url parameter to provide the user with a back link after successful password reset, to support resets initiated by external web applications. Additional parameter delay automatically redirects back after the specified number of seconds has elapsed.


  • 4491: Use lib389 to install 389-ds instead of setup-ds.pl

FreeIPA now utilizes Python-based installer of 389-ds directory server


  • 4580: FreeIPA's LDAP server requires SASL security strength factor of >= 56

Original FreeIPA 4.7.90.pre1 set FreeIPA LDAP server default configuration to require SASL security strength factor higher than 56 bit. However, this change caused "realmd" and other enrollment tools to fail as they expected to be able to retrieve certain information from FreeIPA LDAP server unauthenticated. The change for the server configuration was backed off. We intend to revisit this hardnening later in FreeIPA 4.8 series.



  • 5608: Tech preview: add Dogtag configuration extensions

FreeIPA team started rewrite of the Certificate Authority configuration to make possible passing additional options when configuring Dogtag. This is required to allow use of hardware secure (HSM) modules within FreeIPA CA but also to allow tuning CA defaults. HSM configuration is not yet fully available due to a number of open issues in Dogtag itself.


  • 5803: Add utility to promote CA replica to CRL master

New utility was added to promote a CA replica to be the CRL master. Design page provides more details and use examples.


  • 6077: Support One-Way Trust authenticated by trust secret

Samba integration was updated to allow establishing trust to Active Directory from Windows side using a Trust wizard. This allows to establish a one-way trust authenticated by a shared trust secret. Additionally, it allows to establish a trust with Samba AD DC 4.7 or later, initiated from Samba AD DC side.


  • 6790: Allow creating IPA CA with 3084-bit key.

CA key size default is raised to 3072 instead of 2048 because it's the recommended size by NIST. An extensibility feature added with ticket 5608 allows increasing the CA key size further buta 4096-bit key is considerably slower. The change only affects new deployments. There is no way to upgrade existing CA infrastructure other than issuing a new CA key and re-issuing new certificates to all existing users of the old root CA. In addition, lightweight sub-CAs are currently hard-coded to 2048 bit key size. All relevant public root CAs in the CA/B forum use 2048-bit RSA keys and SHA-256 PKCS#1 v1.5 signatures.


  • 7193: Warn or adjust umask if it is too restrictive to break installation

FreeIPA deployment now enforces own umask settings that are known to work at install time at hardened sites which follow some of STIG recommendations.


  • 7200: ipa-pkinit-manage reports a switch from local pkinit to full pkinit configuration was successful although it was not

The command ipa-pkinit-manage enable|disable is reporting success even though the PKINIT cert is not re-issued. The command triggers the request of a new certificate (signed by IPA CA when state=enable, selfsigned when disabled), but as the cert file is still present, certmonger does not create a new request and the existing certificate is kept.

The fix consists in deleting the cert and key file before calling certmonger to request a new cert.


  • 7206: Provide an option to include FQDN in IDM topology graph

In the replication topology graph visualization, it is now possible to see a fully qualified name of the server. This change helps to reduce confusion when managing complex multi-datacenter topologies.


  • 7365: make kdcproxy errors in httpd error log less annoying in case AD KDCs are not reachable

Log level for technical messages of a KDC proxy was reduced to keep logs clean.


  • 7451: Allow issuing certificates with IP addresses in subjectAltName

FreeIPA now allows issuing certificates with IP addresses in the subject alternative name (SAN), if all of the following are true:

    • One of the DNS names in the SAN resolves to the IP address (possibly through a CNAME).
    • All of the DNS entries in the resolution chain are managed by this IPA instance.
    • The IP address has a (correct) reverse DNS entry that is managed by this IPA instance

  • 7568: FreeIPA no longer supports Python 2

Removed Python 2 related code and configuration from spec file, autoconf and CI infrastructure. From now on, FreeIPA 4.8 requires at least Python 3.6. Python 2 packages like python2-ipaserver or python2-ipaclient are no longer available. PR-CI, lint, and tox aren't testing Python 2 compatibility anymore.


  • 7632: Allow IPA Services to Start After the IPA Backup Has Completed

ipa-backup gathers all the files needed for the backup, then compresses the file and finally restarts the IPA services. When the backup is a large file, the compression may take time and widen the unavailabity window. This fix restarts the services as soon as all the required files are gathered, and compresses after services are restarted.


  • 7619, 7640, 7641: UI migration, password reset and configuration pages support translations

Static pages in FreeIPA web UI now allow translated content


  • 7658: sysadm_r should be included in default SELinux user map order

sysadm_r is a standard SELinux user role included in Red Hat Enterprise Linux.


  • 7667: Use only TLS 1.2 by default

TLS 1.3 is causing some trouble with client cert authentication. Conditional client cert authentication requires post-handshake authentication extension on TLS 1.3. The new feature is not fully implemented yet. TLS 1.0 and 1.1 are no longer state of the art and now disabled by default. TLS 1.2 works everywhere and supports perfect forward secrecy mode (PFS).


  • 7689: Domain Level 0 is no longer supported

Code to support operation on Domain Level 0 is removed. In order to upgrade to FreeIPA 4.8.0 via replication, an existing deployment must first be brought up to Domain Level 1.


  • 7716: [RFE] remove "last init status" from ipa-replica-manage list <node> if it's None.

If a supplier or consumer of LDAP replication data has never done a total update, its status is not shown anymore in "ipa-replica-manage list" output


  • 7747: Support interactive prompt for NTP options for FreeIPA

FreeIPA now asks user for NTP source server or pool address in interactive mode if there is no server nor pool specified and autodiscovery has not found any NTP source in DNS records.


  • 7892: hidden / unadvertised IPA replica

A hidden replica is an IPA master server that is not advertised to clients or other masters. Hidden replicas have all services running and available, but none of the services has any DNS SRV records or enabled LDAP server roles. This makes hidden replicas invisible for service discovery. Design document provides more details on use cases and management of hidden replicas.


  • PyPI packages have fewer dependencies

The official PyPI packages ipalib, ipapython, ipaplatform, and ipaclient no longer depend on the binary extensions netifaces and python-ldap by default.
