Description:
------------
ldap_get_entries() does not preserve the correct case of teh attribute names from ldap_search result. 

eg: "objectClass" becomes "objectclass"

if I use ldap_get_attributes() I do not get this problem.

the loss of case is very important as if you try to reinsert these values, the attribute names no longer match the LDAP schema.

Expected result:
----------------
    ["objectClass"]=>
    array(5) {
      ["count"]=>
      int(4)
      [0]=>
      string(3) "top"
      [1]=>
      string(6) "person"
      [2]=>
      string(13) "inetOrgPerson"
      [3]=>
      string(9) "qmailUser"
    }
    [2]=>
    string(11) "objectClass"
  

Actual result:
--------------

this is a snipet of the vardump: As you can see the "objectclass" attribute has lost its camel case


    ["objectclass"]=>
    array(5) {
      ["count"]=>
      int(4)
      [0]=>
      string(3) "top"
      [1]=>
      string(6) "person"
      [2]=>
      string(13) "inetOrgPerson"
      [3]=>
      string(9) "qmailUser"
    }
    [2]=>
    string(11) "objectclass"
