Hi Tunde, I have never tried this before but I will suggest you try your auth systems one at a time to know they are working before implementing them. Nagios uses apache http authentication by default so you should not have any issues with this. Or maybe I am missing something, please correct if I am. Never tried NTLM authentication with nagios so I can't help in that area but you can look at this link <a href="http://www.itefix.no/i2/node/11683">http://www.itefix.no/i2/node/11683</a> I am sure there are pam or kerberos modules that can talk to a dbase like ldap or AD.

If possible, authenticate against Windows AD first, and if not successful, authenticate against the apache htpasswd file (possibly use the htpasswd file like a fall-back/default authentication mechanism). My /etc/httpd/conf.d/nagios.conf file’s content is listed below. I suspect I need to incorporate “AuthType Basic” in there somehow, but I have tried various option (specifying the htppasswd file too, but I usually end up with the authentication not functioning at all) The first access dialog box has the text “Enter username and password for <a href="http://mynagios" target="_blank">http://mynagios</a>” and if I enter a valid Windows AD credential, I get logged in. If instead, I select cancel on this dialog box, I get a second access dialog box with the text “A username and password are being requested by <a href="http://znlnagios" target="_blank">http://znlnagios</a>. The site says: "NAGIOS". If I supply a valid Windows AD credential, I get logged in also. This also brings me to a related issue, I cannot use the “Downtime” module – and any other module by which I can submit a command. I get the message that I am not authorized to submit the command to Nagios. Yet, I have added the user (MYDOMAIN\username and also username) to the relevant sections of the cgi.cgi file. Thanks.
