Follow-up to myself,

As you see, no proxying (no suffix module at all) nor EAP-Message in the
debug log.

Ah, there is a suffix instance but it does nothing, noop.

I have looked at other occasions where NT-Password gets used (e.g. we
have a vserver which pulls it out of SQL). I guess I should be seeing
that normify() outputs something in the debug output I sent - but not at
all. It is hex-encoded though, so the RDEBUG2 inside normify can't
possibly be silent.

This makes me believe that the NT-Password is not actually evaluated .
But then again, the log also says that the line matched, so it should
really get going.

Wondering about inst->normify - that's inside an if. Maybe it is false,
so pw_found is set to true, but the normifying is never done? I also see
that instantiate() does not set inst->normify. Does it have to? Not good
enough in C to answer this.

Found that it is set in config. My pap module config is really minimal:
        pap {
                auto_header = no
        }

It doesn't set normalise, and as per code it then defaults to "yes". So inst->normify should do its job.

Which means I'm more clueless than before, if that's even possible :-(

I should also note that other clients are mapped to the same virtual
server - and check the password correctly. It only fails
deterministically for two clients of that virtual server.

Are you sure it's definitely the pap module that's setting
Auth-Type? If you comment it out, does the blank password still
authenticate?

If so, a binary chop on your config to find the culprit may be
helpful.
