Overview

Htgroup accesses apache-compatible group files. Htgroup can be used to provide group-based authentication for users. Currently Htgroup is not directly integrated with any authenticators in WEBrick. For security, the path for a digest password database should be stored outside of the paths available to the HTTP server.

Example:

htgroup = WEBrick::HTTPAuth::Htgroup.new 'my_group_file'
htgroup.add 'superheroes', %w[spiderman batman]

htgroup.members('superheroes').include? 'magneto' # => false
