Deploy
======

Launch
------

LdapCherry is launched using the internal cherrypy server:


.. sourcecode:: bash

    # ldapcherryd help
    $ ldapcherryd -h

    # launching ldapcherryd in the forground
    $ ldapcherryd -c /etc/ldapcherry/ldapcherry.ini

    # launching ldapcherryd as a daemon
    $ ldapcherryd -c /etc/ldapcherry/ldapcherry.ini -p /var/run/ldapcherry/ldapcherry.pid -d

Roles and Attributes Configuration
----------------------------------

General Configuration
---------------------

Webserver
~~~~~~~~~

LdapCherry uses the embedded http server of CherryPy, however it has some limitations:

* no listening on port 80/443 (unless run as root, which is strongly discourage)
* no https

The simpler way to properly deploy LdapCherry is to run it listening only on localhost 
with a port above 1024 and put it behind an http server like nginx, apache or lighttpd 
acting as a reverse http(s) proxy.

    [/static]
    tools.staticdir.on = True
    tools.staticdir.dir = '/usr/share/ldapcherry/static/'

Authentication and sessions
~~~~~~~~~~~~~~~~~~~~~~~~~~~

LdapCherry supports several authentication modes:

+------------------------+---------+---------------------+------------------------------------------------+---------------------------------+
|        Parameter       | Section |     Description     |                  Values                        |             Comment             |
+========================+=========+=====================+================================================+=================================+
| auth.mode              | auth    | Authentication mode | * 'and' (user must auth on all backends)       |                                 |
|                        |         |                     | * 'or' (user must auth on one of the backends) |                                 |
|                        |         |                     | * 'none' (disable auth)                        |                                 |
|                        |         |                     | * 'custom' (use custom auth module)            |                                 |
+------------------------+---------+---------------------+------------------------------------------------+---------------------------------+
| auth.module            | auth    | Custom auth module  | python class path to module                    | only used if auth.mode='custom' |
+------------------------+---------+---------------------+------------------------------------------------+---------------------------------+
| tools.sessions.timeout | global  | Session timeout in  | Number of minutes                              |                                 |
|                        |         | minutes             |                                                |                                 |
+------------------------+---------+---------------------+------------------------------------------------+---------------------------------+

Different session backends can also be configured (see CherryPy documentation for details)

.. sourcecode:: ini

    [global]
    # session configuration
    # activate session
    tools.sessions.on = True
    # session timeout in minutes
    tools.sessions.timeout = 10
    # file session storage(to use if multiple processes, 
    # default is in RAM and per process)
    #tools.sessions.storage_type = "file"
    # session 
    #tools.sessions.storage_path = "/var/lib/ldapcherry/sessions"

    [auth]
    # Auth mode
    # * and: user must authenticate on all backends
    # * or:  user must authenticate on one of the backend
    # * none: disable authentification
    # * custom: custom authentification module (need auth.module param)
    auth.mode = 'or'

    # custom auth module to load
    #auth.module = 'ldapcherry.auth.modNone'

Logging
~~~~~~~

LdapCherry has two loggers, one for errors and applicative actions (login, del/add, logout...) and one for access logs.

Each logger can be configured to log to syslog, file or be desactivated. 

Logging parameters:

+--------------------+---------+---------------------------------+-------------------------------------------------+----------------------------------------+
|   log.error_file   |  global |   log file for applicative log  |                 path to log file                |  only used if log.error_handler='file' |

+--------------------+---------+---------------------------------+-------------------------------------------------+----------------------------------------+

.. sourcecode:: ini

    [global]

    # logger syslog for access log 
    log.access_handler = 'syslog'
    # logger syslog for error and ldapcherry log 
    log.error_handler = 'syslog'
    # log level
    log.level = 'info'
