We currently have a SalesForce community setup at 21ct.force.com/support
We created a CNAME record (support.21ct.com) that points to 21ct.force.com When we visit support.21ct.com, we are taken to the normal SalesForce login page, not our community login page.
When I go into our SF Org > Customize > Communities > Manage Communities > Force.com, I notice that the 'Site Primary Custom URL' tick box is not checked.
Does this matter?
What are we doing wrong here? How do we get our CNAME to point to the correct place? SF support has been little help on this.
