The error message is pretty clear: This particular LDAP server does not
support server-side sorting.
Besides that you should read RFC 2891 to learn how to generate the
controlValue which specifies which attribute and matching rule
(optional) is used for sorting and whether you want reverse order
(optional). You could try to generate the controlValue with module pyasn1.
