[c-nsp] Finding source of ISIS authentication failure

[John Neiberger]

Yep, that's the one we were looking for. I don't know how we missed it
before. I tried it now and it gave us the info I was looking for. I know I
tried it before, but I think maybe I had it enabled along with other debug
commands and just missed it in the flood of info. It's easy to spot when
you only have that one enabled.

Thanks!
John
