RHCSA Preparation - Script to Configure a Simple OpenLDAP Server

The ability to quickly configure an LDAP (Lightweight Directory Access Protocol) client for accessing user and group accounts is one of the skills you are expected to have when you sit the Red Hat RHSCA exam.

So You Think You Are Ready For The RHCSA Exam?

So you have studied hard, maybe even attended a week or two of formal training, for the Red Hat Certified System Administrator (RHCSA) exam and now you think you are ready to take the actual examination.

This VM, which is in the form of an OVA (Open Virtualization Archive), will work with VMware Workstation 10 or later. Sorry, but if you want to use the VM in other environments,

Software Craftsman Training

A new academy has just opened in North Carolina which adheres to the tenants of the emerging software craftsmanship movement, a movement that bears more resemblance to building trade school programs than to any academic computer science program. Members of the movement strongly believe that creating software is a craft, and that the best way to learn that craft is through total immersion. The RoleModel Software Craftsmanship Academy is the first of its kind in the USA. According to the website: The focused program will take 8 promising individuals through six months of intense, on-site training from May 14 through
