NAME
libssh2_userauth_password_ex - authenticate a session with username and
password
SYNOPSIS
#include <libssh2.h>
int libssh2_userauth_password_ex(LIBSSH2_SESSION *session,
const char *username,
unsigned int username_len,
const char *password,
unsigned int password_len,
LIBSSH2_PASSWD_CHANGEREQ_FUNC((*passwd_change_cb)));
#define libssh2_userauth_password(session, username, password) \
libssh2_userauth_password_ex((session), (username), \
strlen(username), \
(password), strlen(password), NULL)
DESCRIPTION
session - Session instance as returned by libssh2_session_init_ex(3)
username - Name of user to attempt plain password authentication for.
username_len - Length of username parameter.
password - Password to use for authenticating username.
password_len - Length of password parameter.
passwd_change_cb - If the host accepts authentication but requests that
the password be changed, this callback will be issued. If no callback
is defined, but server required password change, authentication will
fail.
Attempt basic password authentication. Note that many SSH servers which
appear to support ordinary password authentication actually have it
disabled and use Keyboard Interactive authentication (routed via PAM or
another authentication backed) instead.
RETURN VALUE
Return 0 on success or negative on failure. It returns LIB-
SSH2_ERROR_EAGAIN when it would otherwise block. While LIB-
SSH2_ERROR_EAGAIN is a negative number, it isn't really a failure per
se.
ERRORS
Some of the errors this function may return include:
LIBSSH2_ERROR_ALLOC - An internal memory allocation call failed.
LIBSSH2_ERROR_SOCKET_SEND - Unable to send data on socket.
LIBSSH2_ERROR_PASSWORD_EXPIRED -
IBSSH2_ERROR_AUTHENTICATION_FAILED - failed, invalid username/password
or public/private key.
