due to linux omiting the final Z(4) in the NTLMv2 reply, and
the need for the windom for LMv2 authentication, here is a new
AuthNTLM ticket request now with length and dom fields.
|
|
this adds new rpc for mschapv2 authentication (21)
deliver the MPPE secret not after the ticket/authenticator
response as cheartext, but include it in the first 128 bit
of the ticket key. and the authenticator in the first 160 bit
of the authenticator random field.

drawterm, factotum, secstore and the auth commands
all had ther own implementation of readcons. we
want to have one common function for this to avoid
the duplication, so putting that in libauthsrv.
introduce PASSWDLEN which makes the use more explicit
than ANAMELEN.

encryption
this is in preparation for replacing DES ticket encryption with
something better. but first need to make the code stop making
assumptions.
the wire encoding of the Ticket might be variable length
with TICKETLEN just giving an upper bound. the details will be
handled by libauthsrv _asgetticket() and _asgetresp() funciotns.
the Authenticator and Passwordreq structures are encrypted
with the random ticket key. The encryption schmeme will depend
on the Ticket format used, so we pass the Ticket* structure
instead of the DES key.
introduce Authkey structure that will hold all the required
cryptographic keys instead of passing DES key.
