+=======
+
+|image0|
+
+Presentation
+------------
+
+`ITSM-NG <https://www.itsm-ng.org/>`__ is a fork of GLPI. The software's main features are: assets management, IT inventory, service desk, dashboards, KB...
+
+ITSM-NG is compatible with OpenID Connect protocol.
+
+OpenID Connect
+--------------
+
+Configuring ITSM-NG
+^^^^^^^^^^^^^^^^^^^
+
+The configuration steps are described on `ITSM-NG wiki <https://wiki.itsm-ng.org/oidc/>`__.
+
+Just set LemonLDAP::NG main portail URL in ``Provider`` field, and define ``Client ID`` and ``Client Secret``.
+
+Configuring LemonLDAP::NG
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If not done yet, configure LemonLDAP::NG as an
+:doc:`OpenID Connect service<..//openidconnectservice>`.
+
+Then add ITSM-NG as a :doc:`new OpenID Connect Relying Party<..//idpopenidconnect>`
+using the following parameters:
+
+* **Client ID**: the same you set in ITSM-NG configuration
+* **Client Secret**: the same you set in ITSM-NG configuration
+* Add the following **exported attributes**:
+   * **given_name**: user's givenName attribute
+   * **family_name**: user's sn attribute
+   * **email**: user's mail attribute
+* **Login and Logout Redirect URIs**: The main URL of ITSM-NG instance
+
+Configuration sample using CLI:
+
+::
+
+     $ /usr/libexec/lemonldap-ng/bin/lemonldap-ng-cli -yes 1 \
+         addKey \
+           oidcRPMetaDataExportedVars/itsmng given_name givenName \
+           oidcRPMetaDataExportedVars/itsmng family_name sn \
+           oidcRPMetaDataExportedVars/itsmng email mail \
+           oidcRPMetaDataOptions/itsmng oidcRPMetaDataOptionsClientID myClientId \
+           oidcRPMetaDataOptions/itsmng oidcRPMetaDataOptionsClientSecret myClientSecret \
+           oidcRPMetaDataOptions/itsmng oidcRPMetaDataOptionsRedirectUris 'https://itsmng.example.com'  \
+           oidcRPMetaDataOptions/itsmng oidcRPMetaDataOptionsPostLogoutRedirectUris 'https://itsmng.example.com' \
+           oidcRPMetaDataOptions/itsmng oidcRPMetaDataOptionsIDTokenSignAlg RS512 \
+           oidcRPMetaDataOptions/itsmng oidcRPMetaDataOptionsIDTokenExpiration 3600 \
+           oidcRPMetaDataOptions/itsmng oidcRPMetaDataOptionsAccessTokenExpiration 3600 \
+           oidcRPMetaDataOptions/itsmng oidcRPMetaDataOptionsBypassConsent 1
+
+.. tip::
+
+   Declare all attributes that you need to map in ITSM-NG configuration. These attributes must be returned by the scopes requested by ITSM-NG.
