Comment (by Ipstenu):

 > Now going into child site's dashboard requires you to re-login cause of
 cookie not being set for all child top level domains.

 That's actually a 'problem' with domain mapping plugins, and I'm 99% sure
 it's from cross-domain scripting protection (which is to say, it's a bad
 idea to inherently trust that foobar.com and bazzot.com are okay sharing
 cookies, and would be something nefarious sorts would abuse).

 I'd call it not a bug but a security feature.
