CURLOPT_USERPWD - user name and password to use in authentication
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_USERPWD, char *userpwd);
Pass a char * as parameter, pointing to a null-terminated login details string
for the connection. The format of which is: [user name]:[password].
When using Kerberos V5 authentication with a Windows based server, you should
specify the user name part with 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 specify the domain name use either Down-Level Logon Name or UPN (User
Principal Name) formats. For example, EXAMPLE\user and
[email protected]
respectively.
Some HTTP servers (on Windows) support inclusion of the domain for Basic
authentication as well.
When using HTTP and
CURLOPT_FOLLOWLOCATION(3), libcurl might perform
several requests to possibly different hosts. libcurl will only send this user
and password information to hosts using the initial host name (unless
CURLOPT_UNRESTRICTED_AUTH(3) is set), so if libcurl follows locations
to other hosts it will not send the user and password to those. This is
enforced to prevent accidental information leakage.
Use
CURLOPT_HTTPAUTH(3) to specify the authentication method for HTTP
based connections or
CURLOPT_LOGIN_OPTIONS(3) to control IMAP, POP3 and
SMTP options.
The user and password strings are not URL decoded, so there's no way to send in
a user name containing a colon using this option. Use
CURLOPT_USERNAME(3) for that, or include it in the URL.
The application does not have to keep the string around after setting this
option.
