Nagios is a wonderful too for monitoring servers. Their web interface is not bad, either. However I am not crazy about using the HTTP Authentication that comes standard.
Is there a way to use another method of authentication? (and I don't mean restricting access by IP address in the .htaccess file) Something with a form-based login would be wonderful, but perhaps there is no such thing. I'm hoping you guys have found something I haven't.

Nagios doesn't care how you have the webserver handle the authentication. Nagios simply takes the authenticated user passed from the webserver to compare against the configuration. You could also disable authentication within Nagios itself and handle authentication in the webserver directly. Doing this would either allow all authenticated users the same access level or would require separate configurations to restrict/limit access to Nagios features.
Here's the link to the Nagios 3.0 CGI Auth documentation.
