(ITS#6910) Ldap fails to start when duplicate entries are in /etc/hosts

If an IP address entry for a host appears more than once in /etc/hosts, slapd fails to start, complaining the port is already in use.

Failed to start slapd. Attempting debug start to determine error. daemon: listen(ldap://zre-ldap002.eng.vmware.com:389, 5) failed errno=98 (Address already in use)

Sample /etc/hosts: zimbra@zre-ldap002:~$ cat /etc/hosts 127.0.0.1 localhost 10.137.242.52 zre-ldap002.eng.vmware.com zre-ldap002 10.137.242.52 zre-ldap002.eng.vmware.com zre-ldap002

It appears that we don't validate whether or not we've already tried to start up on a given interface...
