When I start sync operation with a made up cookie (just some random bytes), the
server replies with a response with result code 2 (Protocol Error).

RFC4533 specifies: "If the server does not recognize the request cookie or the
request is made under different associations or non-equivalent protections, the
server SHALL return the initial content as if no cookie had been provided or
return an empty content with the e-syncRefreshRequired LDAP result code."

RFC2119: "MUST This word, or the terms "REQUIRED" or "SHALL", mean that the
definition is an absolute requirement of the specification."

Expected behavior: either the initial content as if no cookie had been provided
or an empty content with the e-syncRefreshRequired LDAP result code.
