  30 # The authentication strategy for the biblios web
  31 # services is as follows.
  32 #
  33 # 1. biblios POSTs to the authenticate API with URL-encoded
  34 # form parameters 'userid' and 'password'.  If the credentials
  35 # belong to a valid user with the 'editcatalogue' privilege,
  36 # a session cookie is returned and a Koha session created.  Otherwise, an
  37 # appropriate error is returned.
  38 # 2. For subsequent calls to the biblios APIs, the user agent
  39 # should submit the same session cookie.  If the cookie is
  40 # not supplied or does not correspond to a valid session, the API
  41 # will redirect to this authentication API.
  42 # 3. The session cookie should not be (directly) sent back to the user's
  43 # web browser, but instead should be stored and submitted by biblios.
