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