I follow simple steps from guides all over the web:
a) add an user to Nagios via command
htpasswd htpasswd.users username
b) in cgi.cfg file add this user to lines:
authorized_for_system_information=nagiosadmin, username authorized_for_configuration_information=nagiosadmin, username authorized_for_system_commands=nagiosadmin, username authorized_for_all_services=nagiosadmin, username authorized_for_all_hosts=nagiosadmin, username authorized_for_all_service_commands=nagiosadmin, username authorized_for_all_host_commands=nagiosadmin, username
c) restart nagios3 service, even restart apache2 service
but when I try to list anything from nagios web interface it still gives me this annoying message:
It appears as though you do not have permission to view information for any of the services you requested... If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI and check the authorization options in your CGI configuration file.
Where could be a problem please?
