entries in hosts file not used in host lookup

The "host" command only does DNS lookups, and will not read your =
/etc/nsswitch.conf or /etc/hosts files.

Subject: entries in hosts file not used in host lookup
hello
I have a strange problem with the hosts file
quering for 127.0.0.1 and localhost does not use the /stc/hosts file
---------------------------
my /etc/host file:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
---------------------------
my resolv.conf
; generated by /sbin/dhclient-script
search athome.be
nameserver 192.168.0.1
---------------------------
my nsswitch.conf
#
# /etc/nsswitch.conf
#
passwd: files
shadow: files
group: files
hosts: files dns
bootparams: nisplus [NOTFOUND=3Dreturn] files
ethers: files
netmasks: files
networks: files
protocols: files
rpc: files
services: files
netgroup: files
publickey: nisplus
automount: files
aliases: files nisplus
then:
host 127.0.0.1
Host 1.0.0.127.in-addr.arpa not found: 2(SERVFAIL)
and
Host localhost not found: 3(NXDOMAIN)

if a put a dummy entry in hosts file eg
10.0.0.10 dummy.domain.org
hosts won't resolve it
I think the problem comes down to the fact that host does not read my
/etc/hosts file but does query the configured DNS instead wich does
not reply for such a query, but how can I setup networking this will
work.
Originally I was testing the openldap suite but tests failed due to
localhost lookup :((, and I needed openldap as a JNDI implementation
:(((
Any advice would be apriciated
