if you omit some keys of the dictionnary, the default value for these keys is used.
* ``CAS_INFO_MESSAGES``: Messages displayed in info-boxes on the html pages of the default templates.
It is a dictionnary mapping message name to a message dict. A message dict has 3 keys:
* ``message``: A unicode message to display, potentially wrapped around ugettex_lazy
* ``discardable``: A boolean, specify if the users can close the message info-box
* ``type``: One of info, success, info, warning, danger. The type of the info-box.
``CAS_INFO_MESSAGES`` contains by default one message, ``cas_explained``, which explain
roughly the purpose of a CAS. The default is::
{
"cas_explained": {
"message":_(
u"The Central Authentication Service grants you access to most of our websites by "
u"authenticating only once, so you don't need to type your credentials again unless "
u"your session expires or you logout."
),
"discardable": True,
"type": "info", # one of info, success, info, warning, danger
},
}
* ``CAS_INFO_MESSAGES_ORDER``: A list of message names. Order in which info-box messages are
displayed. Use an empty list to disable messages display. The default is ``[]``.
* ``CAS_LOGIN_TEMPLATE``: Path to the template showed on ``/login`` then the user
is not autenticated. The default is ``"cas_server/login.html"``.
* ``CAS_WARN_TEMPLATE``: Path to the template showed on ``/login?service=...`` then
