Unfortunately, not.  You need to have a syntax definition to use the 
server side sorting. Note: you could do sorting in the client side 
without schema.
$ man ldapsearch
        -S attribute
               Sort the entries returned based on  attribute.  The 
default  is  not  to  sort
               entries  returned.   If attribute is a zero-length string 
(""), the entries are
               sorted by the components of their Distinguished Name.   
See  ldap_sort(3)  for
               more  details.  Note that ldapsearch normally prints out 
entries as it receives
               them. The use of the -S option defeats this behavior, 
causing all entries to be
               retrieved, then sorted, then printed.
