The Cisco AnyConnect client exhibits some quirky behavior on fields
with certain names:
For "answer", "whichpin", and "new_password", the field is renamed to
"password" in the submission.
For "verify_pin" and "verify_password", the field is omitted entirely.
One might expect the client to perform a comparison to see if the first
password/PIN field matches the verify_* field, but in my testing, I didn't
actually see it doing so.
