      PHPBB 3.2.0-RC1 is unable to authenticate against a SMTP Server when trying to send emails.

      Repro:

      • Configure Login Authentication
      • Try to authenticate by sending a testmail - in my case Exchange 2013.

      Analysis:

      Exchange shows the following diag in receive connector logs -

      Sniffering in Wireshark shows that instead of sending the correct password to the server, only a collection of "*" (asterisk) is sent. See below

      Username and PWD are base64 encoded, so lets decode that -

      bm9yZXBseUBoaWhvc29mdC5hdA== -> noreply@hihosoft.at
      KioqKioqKio= -> ********

      It seems that we pass a wrong value to whichever component is trying to authenticate, therefore failing auth.
