User management is often one of the most tedious and yet important aspects of any system. It lays the foundation for many other system functions, such as security and notifications.

In this chapter, we will look at the different options to create user accounts in JIRA and also how to manage users with groups and project roles. We will also look at how to integrate JIRA with external user management systems such as LDAP for both authentication and user management. Lastly, we will also cover how to make JIRA participate in various single sign-on environments.
