24 .SH NAME
25 CURLOPT_SASL_IR \- enable sending initial response in first packet
26 .SH SYNOPSIS
27 #include <curl/curl.h>
28
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SASL_IR, long enable);
30 .SH DESCRIPTION
31 Pass a long. If the value is 1, curl will send the initial response to the
32 server in the first authentication packet in order to reduce the number of

34 authentication mechanisms:
35
36 * Login
37 * Plain
38 * GSSAPI
39 * NTLM
40 * OAuth 2.0

42 Note: Whilst IMAP supports this option there is no need to explicitly set it,
43 as libcurl can determine the feature itself when the server supports the
44 SASL-IR CAPABILITY.
