--------------------------+-----------------------------
 When trying to post wp.newPost to "blog" on multisite instance via XML-RPC
 (other than main blog aka blog_id=1), the blog doesn't post to the blog_id
 specified, but rather to blog_id = 1.

 '''To replicate:'''

 Post XML (below) to http://myrootmultisite.com/xmlrpc.php:

 {{{
 <?xml version="1.0" encoding="iso-8859-1"?>
 <methodCall>
   <methodName>wp.newPost</methodName>
   <params>
     <param><value>3</value></param>
     <param><value>USERNAME</value></param>
     <param><value>PASSWORD</value></param>
     <param>
       <value>
         <struct>
           <member>
                 <name>post_type</name>
                 <value><string>post</string></value>
                 </member>
                 <member>
                         <name>post_title</name>
                         <value><string>Test XML-RPC Post</string></value>
                 </member>
                 <member>
                         <name>post_content</name>
                         <value><string>Content of the
 post.</string></value>
                 </member>
         </struct>
       </value>
     </param>
   </params>
 </methodCall>
 }}}

 '''Expected result:''' post is created under blog_id 3.
 '''Actual result:''' post is created under blog_id 1.

 It's presumably ignoring blog_id.

 '''Workaround'''

 Workaround is to change domain to blog_id's domain (ex:
 mysite.multisite.com) rather than root domain (ex: multisite.com). This
 does not work for me, as I'm using domain mapping and cannot create an SSL
 Cert for every domain name.
