NAME

       CURLOPT_USERNAME - user name to use in authentication

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_USERNAME,
                                 char *username);

DESCRIPTION

       Pass  a  char * as parameter, which should be pointing to the zero terminated user name to
       use for the transfer.

       CURLOPT_USERNAME(3) sets the user name to be used in protocol authentication.  You  should
       not use this option together with the (older) CURLOPT_USERPWD(3) 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 don't
       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
       CURLOPT_PASSWORD(3) and CURLOPT_LOGIN_OPTIONS(3) options.
