checkpw, APOP

[Dave Sill]

I installed Shinya Ohira's checkpw checkpassword replacement, and it
works fine with "checkpw" (standard USER + PASS authentication), but
with "checkapoppw" I get "authorization failed". I'm using fetchmail,
but I have the same problem when I "manually" generate the APOP hash.

How can I debug this?
