Major Description
Though Guacamole currently provides a nice, searchable interface for viewing connection history, it is not possible to download that history without manually exporting it from the database using SQL. Besides being inconvenient for administrators with access only to the web interface, as other authentication backends with admin functionality are written, it will not necessarily always be the case that those backend will provide their own means of exporting history.
The Guacamole admin interface should provide its own means of exporting the connection history to some standard file format, like CSV, such that administrators can easily download the connection history for external processing/auditing.
