# This class' prime objective is to obtain a session token on a Mattermost
# instance with SSO configured where this GitLab instance is the provider.
#
# The process depends on OAuth, but skips a step in the authentication cycle.
# For example, usually a user would click the 'login in GitLab' button on
# Mattermost, which would yield a 302 status code and redirects you to GitLab
# to approve the use of your account on Mattermost. Which would trigger a
# callback so Mattermost knows this request is approved and gets the required
# data to create the user account etc.
#
# This class however skips the button click, and also the approval phase to
# speed up the process and keep it without manual action and get a session
# going.
