Replaced ldap_get_entries with ldap_first_entry/ldap_next_entry and ldap_get_attributes, to fetch information from the ldap with the correct casing
Changed getAttributes function to always return an array of values, because ldap supports multiple values for an attribute
Added a very simple netgroup support
