Ah... I didn't think about that.

But it seems that I accidentally generated the correct hash.  The
resources should be stringprepped according to the Resourceprep
profile, which doesn't fold case, even though both the username (by
Nodeprep) and the server (by Nameprep) do.  So you need to split the
JIDs and stringprep the parts separately.
