The above doesn't mention mod_proxy_fcgi at all, which I mentioned I  
was using. It turns out that mod_proxy_fcgi (at least in Apache 2.4.6)  
doesn't pass on the authorization. Bummer. After fixing that, I also  
found out that there is a default 30 seconds timeout, which also  
doesn't go well with ActiveSync. In addition to the existing  
configurations, adding the following to the Apache configuration made  
things work again:

<IfModule mod_proxy_fcgi.c>
         SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1

         <Proxy fcgi://127.0.0.1:9000>
                 ProxySet timeout=3600
         </Proxy>

         ProxyPassMatch ^/(.*\.php(/.*)?)$  
fcgi://127.0.0.1:9000/srv/www/htdocs/$1
</IfModule>

It seems that things are back in working order.
