LINUX CA Certificate Deployment

Creating an in house signing [aka CA] certificate is a common practice; this allows you to generate free cerficates for internal use. For Windows hosts distributing this CA certificate to all the clients and relevant servers can be accomplished using Active Directory GPOs.

Recent distributions have eased this process considerably by including a quasi-standardized set of scripts and certificate store locations.
