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.
Earlier today I was troubleshooting NFS or Network File System issues on a Ubuntu Linux server and ran into some specific errors. Luckily the errors were easily resolved by restarting portmap on the server. Below I show the error output on the server end in more detail, how to resolve the issue, and testing the Network File System mount from OSX.
