Chapter 38. Authentication and Interoperability
Use of AD and LDAP sudo providers
The Active Directory (AD) provider is a back end used to connect to an AD server. Starting with Red Hat Enterprise Linux 7.2, using the AD sudo provider together with the LDAP provider is available as a Technology Preview. To enable the AD sudo provider, add the
sudo_provider=ad setting in the [domain] section of the sssd.conf file. (BZ#1068725)
DNSSEC available as Technology Preview in IdM
Identity Management (IdM) servers with integrated DNS now support DNS Security Extensions (DNSSEC), a set of extensions to DNS that enhance security of the DNS protocol. DNS zones hosted on IdM servers can be automatically signed using DNSSEC. The cryptographic keys are automatically generated and rotated.
Users who decide to secure their DNS zones with DNSSEC are advised to read and follow these documents:
- DNSSEC Operational Practices, Version 2: http://tools.ietf.org/html/rfc6781#section-2
- Secure Domain Name System (DNS) Deployment Guide: http://dx.doi.org/10.6028/NIST.SP.800-81-2
- DNSSEC Key Rollover Timing Considerations: http://tools.ietf.org/html/rfc7583
Note that IdM servers with integrated DNS use DNSSEC to validate DNS answers obtained from other DNS servers. This might affect the availability of DNS zones that are not configured in accordance with recommended naming practices described in the Red Hat Enterprise Linux Networking Guide: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/ch-Configure_Host_Names.html#sec-Recommended_Naming_Practices. (BZ#1115294)
Identity Management JSON-RPC API available as Technology Preview
An API is available for Identity Management (IdM). To view the API, IdM also provides an API browser as Technology Preview.
In Red Hat Enterprise Linux 7.3, the IdM API was enhanced to enable multiple versions of API commands. Previously, enhancements could change the behavior of a command in an incompatible way. Users are now able to continue using existing tools and scripts even if the IdM API changes. This enables:
- Administrators to use previous or later versions of IdM on the server than on the managing client.
- Developers to use a specific version of an IdM call, even if the IdM version changes on the server.
In all cases, the communication with the server is possible, regardless if one side uses, for example, a newer version that introduces new options for a feature.
For details on using the API, see https://access.redhat.com/articles/2728021 (BZ#1298286)
Containerized Identity Management server available as Technology Preview
The
rhel7/ipa-server container image is available as a Technology Preview feature. Note that the rhel7/sssd container image is now fully supported.
For details, see https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html-single/using_containerized_identity_management_services. (BZ#1405325, BZ#1405326)
The Custodia secrets service provider is available as a Technology Preview
As a Technology Preview, you can use Custodia, a secrets service provider. Custodia stores or serves as a proxy for secrets, such as keys or passwords.
For details, see the upstream documentation at http://custodia.readthedocs.io.
Note that since Red Hat Enterprise Linux 7.6, Custodia has been deprecated. (BZ#1403214)
