 Another option is to have an authentication server that can verify user credentials in an LDAP server.
 If an incoming request to the Zeppelin server does not have a cookie with user information encrypted with the authentication server public key, the user
 is redirected to the authentication server. Once the user is verified, the authentication server redirects the browser to a specific URL in the Zeppelin server which sets the authentication cookie in the browser.
-The end result is that all requests to the Zeppelin web server have the authentication cookie which contains user and groups information.

 In this section, we will explain the detail about how the notebook authorization works in backend side.
 
-#### NotebookServer
+### NotebookServer
 The [NotebookServer](https://github.com/apache/zeppelin/blob/master/zeppelin-server/src/main/java/org/apache/zeppelin/socket/NotebookServer.java) classifies every notebook operations into three categories: **Read**, **Write**, **Manage**.
 Before executing a notebook operation, it checks if the user and the groups associated with the `NotebookSocket` have permissions. 
 For example, before executing a **Read** operation, it checks if the user and the groups have at least one entity that belongs to the **Reader** entities.
 
-#### Notebook REST API call
+### Notebook REST API call
 Zeppelin executes a [REST API call](https://github.com/apache/zeppelin/blob/master/zeppelin-server/src/main/java/org/apache/zeppelin/rest/NotebookRestApi.java) for the notebook permission information.
 In the backend side, Zeppelin gets the user information for the connection and allows the operation if the users and groups
 associated with the current user have at least one entity that belongs to owner entities for the notebook.

+## Overview
 [Apache Shiro](http://shiro.apache.org/) is a powerful and easy-to-use Java security framework that performs authentication, authorization, cryptography, and session management. In this documentation, we will explain step by step how Shiro works for Zeppelin notebook authentication.
