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
       LIBSSH2_ERROR_EAGAIN    when    it   would   otherwise   block.   While
       LIBSSH2_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.
