CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SOCKS5_GSSAPI_NEC, long nec);
DESCRIPTION
Pass a long set to 1 to enable or 0 to disable. As part of the GSSAPI
negotiation a protection mode is negotiated. The RFC 1961 says in
section 4.3/4.4 it should be protected, but the NEC reference
implementation does not. If enabled, this option allows the
unprotected exchange of the protection mode negotiation.
DEFAULT
