LdapCherry also aims to be as simple as possible to deploy: no crazy dependencies,

Implementing your own backend
=============================
Implementing cutom backends
===========================
API
~~~
---
To create your own backend, you must implement the following API:
The backend modules must respect the following API:
.. automodule:: ldapcherry.backend
:members:
.. autoclass:: ldapcherry.backend.Backend
:members: __init__, auth, add_user, del_user, set_attrs, add_to_groups, del_from_groups, search, get_user, get_groups

by **self.get_param**:

Exceptions

----------
The following exception can be used in your module
*
*
*
*
.. automodule:: ldapcherry.exceptions
:members: UserDoesntExist, UserAlreadyExists, GroupDoesntExist
:undoc-members:

These exceptions permit a nicer error handling and avoid a generic message to be thrown at the user.

Roles Configuration
~~~~~~~~~~~~~~~~~~~
The roles configuration is done in a yaml file (roles.yml by default).
Mandatory parameters
^^^^^^^^^^^^^^^^^^^^
Roles are seen as an aggregate of groups:
.. sourcecode:: yaml
<role id>:
display_name: <Role display name in LdapCherry>
description: <human readable role description>
backends_groups: # list of backends
<backend id 1>: # list of groups in backend
- <b1 group 1>
- <b1 group 2>
<backend id 2>:
- <b2 group 1>
- <b2 group 2>
.. warning:: <role id> must be unique, LdapCherry won't start if it's not
Defining LdapCherry Administrator role
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
One of the declared roles must be tagged to be LdapCherry administrators.
Doing so is done by setting **LC_admins** to **True** for the selected role:
.. sourcecode:: yaml
<role id>:
display_name: <Role display name in LdapCherry>
description: <human readable role description>
LC_admins: True
backends_groups: # list of backends
<backend id 1>: # list of groups in backend
- <b1 group 1>
- <b1 group 2>
<backend id 2>:
- <b2 group 1>
- <b2 group 2>
Nesting roles
^^^^^^^^^^^^^
LdapCherry handles roles nesting:
.. sourcecode:: yaml
parent_role:
display_name: Role parent
description: The parent role
backends_groups:
backend_id_1:
- b1_group_1
- b1_group_2
backend_id_2:
- b2_group_1
- b2_group_2
subroles:
child_role_1:
display_name: Child role 1
description: The first Child Role
backends_groups:
backend_id_1:
- b1_group_3
child_role_2:
display_name: Child role 2
description: The second Child Role
backends_groups:
backend_id_1:
- b1_group_4
