Neither libssh2_userauth_password_ex() nor libssh2_userauth_keyboard_interactive_ex() would return a login failure error if the server responded with a SSH_MSG_USERAUTH_FAILURE, instead you would see whatever previous error had occurred, typically LIBSSH2_ERROR_EAGAIN. This patch changes error code -18 to LIBSSH2_ERROR_AUTHENTICATION_FAILED and makes LIBSSH2_ERROR_PUBLICKEY_UNRECOGNIZED an alias for LIBSSH2_ERROR_AUTHENTICATION_FAILED. In addition, new logic in userauth_password() properly handles SSH_MSG_USERAUTH_FAILURE and both this function and userauth_keyboard_interactive() now properly return LIBSSH2_ERROR_AUTHENTICATION_FAILED.

.SH NAME
|
|
libssh2_userauth_password_ex - authenticate a session with username and password
|
|
.SH 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)));
|
|
|
|
int
|
|
libssh2_userauth_password(LIBSSH2_SESSION *session, const char *username, const char *password);
|
|
|
|
.SH DESCRIPTION
|
|
\fIsession\fP - Session instance as returned by
|
|
.BR libssh2_session_init_ex(3)
|
|
|
|
\fIusername\fP - Name of user to attempt plain password authentication for.
|
|
|
|
\fIusername_len\fP - Length of username parameter.
|
|
|
|
\fIpassword\fP - Password to use for authenticating username.
|
|
|
|
\fIpassword_len\fP - Length of password parameter.
|
|
|
|
\fIpasswd_change_cb\fP - 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.
|
|
|
|
.SH RETURN VALUE
|
|
Return 0 on success or negative on failure. It returns
|
|
LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
|
|
LIBSSH2_ERROR_EAGAIN is a negative number, it isn't really a failure per se.
|
|
|
|
.SH ERRORS
|
|
\fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed.
|
|
|
|
\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.
|
|
|
|
\fILIBSSH2_ERROR_PASSWORD_EXPIRED\fP -
|
|
|
|
\fLIBSSH2_ERROR_AUTHENTICATION_FAILED\fP - failed, invalid username/password or public/private key.
