Well the odd thing is that you're using the EXTERNAL mech, which doesn't do
any parsing (or anything else) at all.
Taking a quick tour thru the Cyrus code, I remember now what it does... The
client's -R realm is only checked if the server presents a list of multiple
realms to choose from. If the server only presents a single realm, the client
uses it implicitly and ignores anything the user might have specified
with -R. But on the server, the SASL plugins (except EXTERNAL) always parse
the provided username: strchr(input, '@') and split that into user & realm.
So there's a bunch of junk going on in Cyrus SASL that's going to prevent
this from ever working.
