It varies upon the installation - in particular what services are running. Check /etc/passwd to show the list of user accounts for your installation.
As an example, if you are running a webserver, you probably have a user called "apache" or "httpd" installed. If you are running a database, you'll have "mysql" or "postgres" users installed, etc.
