CNAME and DM example

I’m looking for both a CNAME and Domain Mapping example. My configuration is not mapping my domain, instead it’s doing a permanent redirect.

My configuration is as follows:

For mydomain.com CNAME record:

Host Name = *
Address = otherdomain.com

My DM for mydomain.com:

Site ID = 2 (site1.otherdomain.com)
Domain = mydomain.com
Primary = NO

My DM Options:

Server CNAME domain [otherdomain.com]
[X] Remote Login
[ ] Permanent redirect (better for your blogger's pagerank)
[X] User domain mapping page
[X] Redirect administration pages to site's original domain (remote login disabled if this redirect is disabled)
[ ] Disable primary domain check. Sites will not redirect to one domain name. May cause duplicate content issues.

My .htaccess:

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
# END WordPress
