How to Configure a custom domain name for the Autotask Client acess portal

Our company is a recent convert to Autotask, a practice management software for the IT consulting industry.  One of the great features is the ability for us to deploy a customer portal to view tickets, invoices, and other information regarding their service.  Because autotask is hosted we end up with a long URL to hand to customers similar to https://clientaccess.autotask.net/client=881920 – This is a problem for me because I like to keep things simple for the client.  I thought about a cname but because it isn’t just a hostname this won’t work.   Digging around my domain at Godaddy I noticed that they had a feature called “forwarding” – It only works for parked domains so making a third level domain or cname was not an option.  This wasn’t a huge problem for me so I bought a new domain name and enabled forwarding . . . a short 24 hours processing time later it was up and functioning perfectly.
