I'm running 2.9.
The problem is that the server i'm monitoring uses host headers, so multiple
sites are on 10.10.10.7. The default site for *.7 is a Microsoft CRM site
which requires basic authentication. So even though in services I specify
-H lagarde.lagardeinc.com it seems to just hit the IP listed for the
host which hits Microsoft CRM and nagios reports unauthorized.
