In this blog, we’ll look at how to setup and troubleshoot the Percona PAM authentication plugin.

We occasionally get requests from our support clients on how to get Percona Server for MySQL to authenticate with an external authentication service via LDAP or Active Directory. However, we normally do not have access to client’s infrastructure to help troubleshoot these cases. To help them effectively, we need to setup a testbed to reproduce their issues and guide them on how to get authentication to work. Fortunately, we only need to install Samba to provide an external authentication service for both LDAP and AD.

In this article, I will show you how to (a) compile and install Samba, (b) create a domain environment with Samba, (c) add users and groups to this domain and (d) get Percona Server …

I use a MacBook Pro for my day-to-day operations here at CB1, INC. I’m a huge believer that a development environment should mimic the production environment, so I find myself running a couple virtual machines in VMware Fusion.

The following guide is a reference for myself as well as possibly a helpful resource for setting up your own Linux development environment. Here’s an checklist of the tasks to perform and software to install:

• Operating System
  • Ubuntu 10.10 64-bit: I use Ubuntu Desktop in dev and Ubuntu Server in production
  • Package updates and upgrades
  • Network configuration (at least 2 static IP addresses)
• Development Tools
  • C/C++ development environment
  • Autotools
  • Sun Java JDK

Background Knowledge

With the use of Samba we are able to share files through a local network and make it appear as if the files are on the Mac OS X locally. The instructions below will step you through step by step on how to access files from the Mac OS X to a Windows XP/Vista™ system through the network.

NOTE: Instructions to unblock network traffic through a software/hardware firewall are not provided. Refer to your software/network manual or support web site for details.

NOTE: These instructions will not allow for sharing via the Internet.

Solution

Setting up a file share in Windows XP

1. Open Windows Explorer/My Computer (press Windows Key+E) or go to the Windows Start Menu -> Programs -> Accessories -> Windows Explorer.
2. Browse to a folder you wish to share and right mouse click on it and left mouse click on “Properties”. …

Matt Asay is pushing his favorite Open Source model again. The model where the majority of developers of a project work for a company and that company is creating a business around the project. There's nothing wrong with that model, but he seems to forget the other models time over time :)

Matt is absolutely right with 2 of the 3 things he wants you to consider.
A SI in the middle of a $50 million dollar project involving Alfresco not talking to Alfresco is just wrong. An SI not offering a support contract is also just wrong. But an SI forcing his customer to buy the commercially supported version from a vendor ? Where's the customer choice ?

The customer should have the option to choose for a commercially supported version or the free version. And preferably that should be an educated option.

Matt seems to forget about situations where …

Here's my presentation I gave June 9, 2008, at the Twin Cities MySQL and PHP User Group about my highly available cluster using DRBD and Heartbeat.

I added a few slides and cleaned things up a bit. The presentation went well and we had a lot of good questions.

The MySQL and PHP User Group will be taking some time off over the summer. There will be another meetup mid-summer to come up with some ideas for future meetings.
