That is really true, especially at universities (as opposed to liberal arts colleges). Even when I was tenured at a LAS, it was clear that my research mattered more than my teaching, though the latter had to be respectable. At my current research university, the only way teaching matters in gaining tenure is that you aren't an embarrassment; I've seen a lot of mediocre teachers get tenure based on research/grant-getting, and in our discussions about a tenure candidate, teaching of undergraduates is barely mentioned.
