.TH CURLOPT_USERNAME 3 "April 26, 2023" "ibcurl 8.3.0" libcurl

|
.SH NAME
|
|
CURLOPT_USERNAME \- user name to use in authentication
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_USERNAME,
|
|
char *username);
|
|
.SH DESCRIPTION
|
|
Pass a char * as parameter, which should be pointing to the null-terminated
|
|
user name to use for the transfer.
|
|
|
|
\fICURLOPT_USERNAME(3)\fP sets the user name to be used in protocol
|
|
authentication. You should not use this option together with the (older)
|
|
\fICURLOPT_USERPWD(3)\fP option.
|
|
|
|
When using Kerberos V5 authentication with a Windows based server, you should
|
|
include the domain name in order for the server to successfully obtain a
|
|
Kerberos Ticket. If you do not then the initial part of the authentication
|
|
handshake may fail.
|
|
|
|
When using NTLM, the user name can be specified simply as the user name
|
|
without the domain name should the server be part of a single domain and
|
|
forest.
|
|
|
|
To include the domain name use either Down-Level Logon Name or UPN (User
|
|
Principal Name) formats. For example, EXAMPLE\\user and user@example.com
|
|
respectively.
|
|
|
|
Some HTTP servers (on Windows) support inclusion of the domain for Basic
|
|
authentication as well.
|
|
|
|
To specify the password and login options, along with the user name, use the
|
|
\fICURLOPT_PASSWORD(3)\fP and \fICURLOPT_LOGIN_OPTIONS(3)\fP options.
|
|
|
|
The application does not have to keep the string around after setting this
|
|
option.
