POD on that method states "Returns the next value to pass to the server or an empty list on error." It would be worthwhile to point out that the result is 'undef' in case of an error while an empty string is a valid challenge (happens with GSSAPI). There is at least one piece of software (Anyevent::XMPP) that got that wrong.
