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. .SH DEFAULT ? .SH PROTOCOLS Most .SH EXAMPLE .nf int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode res; curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/"); curl_easy_setopt(curl, CURLOPT_PROXY, "socks5://proxy"); curl_easy_setopt(curl, CURLOPT_SOCKS5_GSSAPI_NEC, 1L); res = curl_easy_perform(curl); curl_easy_cleanup(curl); } } .fi .SH AVAILABILITY Added in 7.19.4 .SH RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. .SH "SEE ALSO" .BR CURLOPT_SOCKS5_GSSAPI_SERVICE (3), .BR CURLOPT_PROXY (3)
