I stumbled upon this issue as well. I am using ubuntu in a local network
with a local dns server, which serves foo.local hostnames. When I did a
"host bar.foo.local" I got the correct response "Host bar.foo.local has
IP xx.xx.xx.xx"; however f.e. "ping bar.foo.local" gave an "unknown
host" response.

Turned out that resolving was done using multicast dns instead of normal
dns - I discovered that by using a network sniffer.

By googling for "mdns ubuntu" I found this bugreport.

I removed the "mdns4_minimal [NOTFOUND=return]" part from
/etc/nsswitch.conf and that indeed resolved the issue. IMHO that should
be the default for ubuntu.
