Setting Up Percona PAM with Active Directory for External Authentication

In this blog post, we’ll look at how to set up Percona PAM with Active Directory for external authentication.

In my previous article on Percona PAM, I demonstrated how to use Samba as a domain, and how easy it is to create domain users and groups via the samba-tool. Then we configured nss-pam-ldapd and nscd to enumerate user and group information via LDAP calls, and authenticate users from this source.

This time around, I will demonstrate two other ways of using Active Directory for external authentication by joining the domain via SSSD or Winbind. System Security Services Daemon (SSSD) allows you to configure …

Thread_Statistics and High Memory Usage

In this blog post, we’ll look at how using thread_statistics can cause high memory usage.

I was recently working on a high memory usage issue for one of our clients, and made some interesting discoveries: high memory usage with no bounds. It was really tricky to diagnose.

Percona Server for MySQL in Docker Swarm with Secrets

This quick post demonstrates using Percona Server for MySQL in Docker Swarm with some new authentication provisioning practices.

Some small changes to the startup script for the Percona-Server container image allows us to specify a file that contains password values to set as our root user’s secret. “Why do we need this functionality,” I hear you cry? When we use an environment variable, it’s not terribly hard to locate the value to which someone has set as their database root password. Environment variables are not well suited for sensitive data. We preach against leaving our important passwords in easy to reach places. So moving towards something more secure whilst retaining usability is desirable. …
