Why isn't LastPass autofilling the login form?

Problem: You try to login to the DCS Worldwide support site but the username/password isn't getting populated

Cause: The login screen is contained within an iframe (a "window" within the web page) which is loading a site on the zendesk.com domain. LastPass thinks this is insecure as it doesn't match the domain in your browser address bar.

Solution: Open your LastPass value and go to Account Settings -> Equivalent Domains. Add "dcsworldwide.net,zendesk.com"
