That admin tool setting allows you to control the page the client is redirected to after they log into the system on the client side. Look to make that change where within the admin tool:
SITE SETUP > USER ACCOUNT SETTINGS > Post-Login Landing Page
If you go to the above you'll see:
Within that setting you can have the client be directed to the client side admin tool home page, the Geo software front page or another url of your choosing within that other option.
If you choose the other option simply insert the url of the page you wish to forward them to.
