The user password is expired, but the functions "libssh2_userauth_password_ex" or "libssh2_userauth_publickey_fromfile_ex" never fails with LIBSSH2_ERROR_PASSWORD_EXPIRED, following is my code.

There is a specific SSH protocol message code (60) that the server needs to
send for this to happen. Based on the logs, it seems the server does not send
it. Instead, it sends SSH_MSG_USERAUTH_SUCCESS (i.e. it allows the login) then
asks the user to change it interactively instead.
