Indeed. /etc/hosts had "127.0.0.1 host", and not the "real" ip matching dns.

I changed /etc/hosts from 127.0.0.1 to its real ip, and autofs now 
properly detects that "host" is local and uses bind now, as it should. I 
verified this has nothing to do with autofs version and more to do with 
kernel revision.

2.6.32 "works", 2.6.37 is "broken".
