19.1 Introduction

This part of the book describes the tasks and processes that may need to be carried out on a regular basis in order to keep the application in good health and in line with requirements from end users.

Maintenance may require different types of system access for different types of tasks:

1. 1.

   Within application tasks, such as user management, require an appropriately authorized application login

2. 2.

   Database administration tasks, such as creation of backups and application upgrades, require a database level login to be used with (amongst others) ’setup.pl’

3. 3.

   Other system-level maintenance tasks, such as updating PostgreSQL or Apache, which require user accounts on the server hosting LedgerSMB

Each of the above tasks requires its own type of user account. Creating and managing accounts for the first type of task is the subject of the next chapter.
