I disapproved this commit. I do not like workarounds like this, and I
don't think it's even necessary for the latest versions of OpenFire
(tested with 3.4.1). Also, instead of forcing non-SASL DIGEST-MD5 on
everyone we should possibly make it an option. Finally, this commit was
causing crashes for me:
