Discovery and Affinity

Questions related to DNS and service discovery regularly come up during deployments of Identity Management (IdM) in Red Hat Enterprise Linux in a trust configuration with Active Directory. This blog article will shed some light of this aspect of the integration.

We will start with a description of the environment. Let us say that the Active Directory  environment consist of

PCI Series: Requirement 6 – Develop and Maintain Secure Systems and Applications

This post is the fifth installment in my PCI DSS series – a series dedicated to the use of Identity Management (IdM) and related technologies to address the Payment Card Industry Data Security Standard (PCI DSS). This specific post is related to requirement six (i.e. the requirement to develop and maintain secure systems and applications). The outline and mapping of individual articles to requirements can be found in the overarching post that started the series.

Section six of the PCI DSS standard covers guidelines related to secure application development and testing. IdM and its ecosystem can help in multiple ways to address requirements in this part of the PCI-DSS standard. First of all, IdM includes a set of Apache modules for

PCI Series: Requirement 1 – Install and Maintain a Firewall Configuration to Protect Cardholder Data

This article is one of the blog posts dedicated to use of Identity Management (IdM) and related technologies to address the Payment Card Industry Data Security Standard (PCI DSS). This specific post is related to requirement one – install and maintain a firewall configuration to protect cardholder data. The outline and mapping of individual articles to the requirements can be found in the overarching post that started the series.

The first requirement of the PCI standard talks about the firewalls and networking. While Red Hat’s Identity Management solution is not directly related to setting up networks and firewall rules, there are several aspects of IdM that

I Really Can’t Rename My Hosts!

Hello again! In this post I will be sharing some ideas about what you can do to solve a complex identity management challenge.

As the adoption of Identity Management (IdM) grows and especially in the case of heterogeneous environments where some systems are running Linux and user accounts are in the Active Directory (AD) – the question of renaming hosts becomes more and more relevant. Here is a set of requirements that we often hear from customers

Why Use SSSD Instead of a Direct LDAP Configuration for Applications?

In my Identity Management and Application Integration blog post I talk about how applications can make the most of the identity ecosystem. For example, a number of applications have integrated Apache modules and SSSD to provide a more flexible authentication experience.  Despite this progress – some (people) remain unconvinced. They wonder why they should use Apache modules and SSSD in conjunction with, for example, Active Directory instead of using a simple LDAP configuration… essentially asking: why bother?

Let’s look at this scenario in greater detail.  If an application supports

When to Migrate: Red Hat Identity Management vs. Third-Party Solutions

Over last several months, in meetings with many Red Hat customers, I have been asked about best practices related to migration from an existing third-party identity management solution to Red Hat’s Identity Management (IdM) solution. In today’s post I will share some of my thoughts on this matter…

Back to Blogging: New Identity Management Features in RHEL 7.2

Hello again! I have not had time to blog in awhile. What happened? I picked up some additional responsibilities and these consumed a lot of my time. But now… I am back and will be blogging once again.

Time goes on and there are (many) new topics that are worth sharing with you. The first subject that I want to cover is the new Identity Management (IdM) features in Red Hat Enterprise Linux 7.2. While the release happened nearly three months ago – it’s still worth me providing an overview of new features and functionality. Another subject that people often ask about nowadays is the conversion from 3rd party vendor solutions to the IdM offering from Red Hat. We see a lot of interest in this area and I want to share some hints for when it is a good idea to use what we offer and when it might not be. Finally, there are also some emerging technologies

Identity Management and Two-Factor Authentication Using One-Time Passwords

Two-factor authentication, or 2FA, is not something new. It has existed for quite some time and in different forms. What is a ‘factor’? A factor is something you have, something you know, or something you are. For example, if we combine a PIN that you know, with your fingerprint, we get a 2FA based on biometrics. In practice, biometric solutions are not often used because it’s not especially difficult to steal someone’s fingerprint (…and it is quite hard to revoke or replace your finger). The more practical approach to two-factor authentication is to combine something you know, a PIN or password, with something you have.

Something you have often comes in form of

Identity Management and Certificates

Identity Management (IdM) in Red Hat Enterprise Linux includes an optional Certificate Authority (CA) component. This CA is the same CA included with the Red Hat Certificate System (RHCS). If they’re the same, what is the relationship between IdM and RHCS? Is there a secret plan to replace one with another? This post reviews some of the details associated with each of the offerings and explores different use cases – indicating where you might choose to use one solution over the other.
