    Went with Kerberos and everything went smoothly. How do I limit what
users are allowed access?

Here is my Apache config for nagios in case it helps anyone.

<location /"nagios.html">
       AuthType Kerberos
       AuthName "Network Login"
       KrbMethodNegotiate On
       KrbMethodK5Passwd On
       KrbAuthRealms DOMAIN.LOCAL
       require valid-user
       Krb5KeyTab /etc/apache2/conf-enabled/httpd.keytab
       KrbLocalUserMapping On

I had to install Kerberos first for Apache(Debian based)on Ubuntu
14.04.1 LTS

apt-get install libapache2-mod-auth-kerb
