ServiceDesk Plus - SSL Certificates and FQDN Redirect

 In our environment, we use ServiceDesk Plus (On-Prem) for the Helpdesk Ticketing System.

Our Active Directory Domain is single-forest, with Parent and Child Domain.  I am responsible for the Child domain, and that is where the SDP Web Server resides.

Users would access the helpdesk portal via http://hostname:8080.

I needed to install an SSL certificate on the site, which is covered in the SDP documentation: SSL Certificate Install.

Port redirect is also covered in the documentation: HTTP to HTTPS redirect.

However, one of the criteria for using an SSL certificate on a site is that it's signed for the FQDN. Therefore users would need to access the site via https://hostname.child.domain.com:8443. If the user would access the site with just the hostname - https://hostname:8443 the browser would throw a certificate warning.

The solution - not covered in the documentation, and not provided by ManageEngine support, is to edit one of the Tomcat web server configuration files:

Open the file named server.xml.

On my server it was located at: c:\manageengine\servicedesk\webapps\ROOT\WEB-INF

1. Set the proxyName attribute of your Connector elements to the FQDN for your server.
2. Add an alias element to your Host elements
