Can you please elaborate about that setting (where is it found?)
The settings I see are:
1 Remote Login
2 Permanent redirect (better for your blogger’s pagerank)
3 User domain mapping page
4 Redirect administration pages to site’s original domain (remote login disabled if this redirect is disabled)
5 Disable primary domain check. Sites will not redirect to one domain name. May cause duplicate content issues.
I have 1,3,4 ticked
