Can't have the same username on two subdomains with Norton Safe Web

Moved to Norton Toolbar/Identity Safe Board for better exposure.

Hello,

 

When I have two subdomains (for example http://web1.norton.com and http://web2.norton.com) where I want to log in I can't set the two subdomains with the same username in Norton Safe Web.

Anyone knows how to solv this problem?
