Under LDAP Attribute Mapping, clear the fields out on the right side. You need to enter the names of LDAP Attributes there. For NetBIOS Name: just put the word "name" without quotes. For DNS Name: put "dnshostname". Leave the domain name , ip address, and mac address fields blank.
You could try different LDAP search filters. Try leaving it blank or removing the () around your filter.
