Did read that split DNS wiki. Have configured as told there.
Now my ldap fails with err no 99.
daemon: bind(7) failed errno=99 (Cannot assign requested address)
From forum ,i understand its /etc/hosts causing this error.
Here's my /etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.1.1 hostname.local hostname
# The following lines are desirable for IPv6 capable hosts
#::1 localhost ip6-localhost ip6-loopback
Please let me know whats wrong here
