> Base64 decoding doesn't report errors in some platforms.
> When the libSASL library in the system has a bug, sasl_decode64() accepts
> almost anything instead of rerturning a proper error code.
> See details at https://github.com/cyrusimap/cyrus-sasl/issues/619
> This issue was already reported by IMPALA-9926 and IMPALA-13968, but they
> only modified our tests to make them pass in such environments.
> We could add our own implementation for Base64 decoding, or use another
> library that doesn't have this bug (and hopefully neither other bugs).
> The issue is fixed in libSASL, but since we use the library from the system
> we run on, it means we cannot guarantee correct behavior.
