Hi everyone,

it seems that no one has pointed the recent paper
by Bruce Schneier and Peter Mudge

"Cryptanalysis of Microsoft Point to Point
Tunneling Protocol"

it is quite interesting, as it describe in details
problems related to the authentication problem of

However, it doesn't seems to cite any of the work
of Samba team (however, L0phtcrack is cited).

Moreover, I don't undestand fully the relations
about protocols described here and protocols used
inside SAMBA.

For anyone interested, the address for the paper
