Recently, a ssh session terminated while editing a text file. Unfortunately, tmux was not utilized and the session ended abruptly. Not giving it much thought, the server was rebooted and during the dmesg output, the following message was produced: “recovering vi editor session”.

What’s the use of having an OpenLDAP Directory if you do not have any clients connected to it? In this article, attaching a Macintosh 10.9 Client to the OpenLdap Directory with standard schemas and storing the contents of our Home Directory on a NFS File Server is demonstrated.
With the advent of NSA snooping, corporate espionage, and general employee mischief, it’s time to start utilizing encryption to snoop-proof data streams emanating from corporate networks. LDAP is but one of many protocols in which encryption is necessary – see flowchart below. This article will focus on using TLS/SSL on the interconnected streams of data originating from and to an OpenLDAP Server and its dependent services. It will not contain much in the area of OpenLDAP ACL’s as a means to segregate different users and data with differing levels of encryption, nor will it focus on SASL and Kerberos as a means to secure data. Again, these topics will present themselves in a future related article.
