# NAME

# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#include <curl/curl.h>

# 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.
