Paul spake unto us the following wisdom:

Huh.  Can you check your Help | Build Information and tell me what it
says about Cyrus SASL?  If it's enabled, can you rebuild with
--disable-cyrus-sasl and see if that works?

The server uses ejabberd, so that's not the difference there.

I'd have to check the code.
