Am i doing correct?

Hi

I use WordPress 3.4.2. and http://wordpress.org/extend/plugins/wordpress-mu-domain-mapping/ Doncha last version plugin.

Then i use Cpanel with Park Domain to add virtual alias ‘newdomain.com’
(i’m in a shared domain, no access to vhost.conf)

Then from wordpress i add a page and link to ‘newdomain.com’ in dms setting page

But when i search ‘newdomain.com’ i only reach
http://mainmultisite.com/wp-signup.php?new=newdomain.com
(it say that only when ‘newdomain.com’ is parked)

Is DMS compatible with doncha plugin?
Can anybody help me with another tip to get DMS work?

Best regards,
Pescadito
