There are a couple of things you need to do:
(1) Create the authorized user in the contacts.cfg file (by default located in /usr/local/nagios/etc/), and then you may need to add them to whatever contact group in the contactgroups.cfg file.
(2)In the cgi.cfg file, specify what the user has authorization to view or what commands to execute. (3)You'll need to add them to the .htaccess file(s) if you want them to be able to authenticate over the web interface and use the CGIs. The commands to do that are specifically written out for you in the online documentation.
I don't think I've missed anything...
