Authenticate Linux To Active Directory On Windows – Centrify Express

I was working with a coworker today to setup a new Redmine server running on top of Ubunut 12.04 and one of the steps we completed in the process was setting up LDAP authentication in Redmine. Setting up LDAP authentication in Redmine requires the server running Redmine to be joined to the Windows Active Directory domain so I needed a quick way to auth Linux on Active Directory. I have used Centrify in the past and remember it being really easy to setup authentication from any form of Linux to a Windows domain and again it did not disappoint. Follow the directions below to join a Linux server to Active Directory using Centrify.

Title OSX Keyboard Shortcut For Insert Date And Time, Insert Date/Time In TextMate

I use TextMate on Mac OSX Mountain Lion to write notes. One thing I find myself needing a bunch is to insert the current date and time so I can track specific events. For instance if I am writing an article for Question-Defense.com and I am doing the initial formatting in TextMate, which is a typical scenario for me, I might take ten screenshots and I like to note the current date/time in case I get pulled away from the article writing for something else. So having a keyboard shortcut that outputs the current date/time is really valuable so I don’t have to type it out by hand. Below I describe how to install a OSX Service that will provide various date/time outputs via Keyboard Shortcuts. The OSX Service called WordService also provides a bunch of extra awesome services which I briefly touch on below as well.
