redirecting to parked domain results in subdomain

I set up mulisite and everything seems to run ok but then I tried to park a domain through cpanel. When I go to the secondary domain, I am directed to a subdomain.primarydomain/sighnup. I would like the secondary domain just to redirect to the primary but I’m not sure how to use the parked domain with the multisite. The main domain is http://www.411forfathers.com and the secondary is 4114fathers.com. I want 4114fathers just to end up at 411forfathers.com. Any help would be great.
