SSHD pubkey authentication

SSHD pubkey authentication

[Lapo Luchini]

It is possible to use pubkey authentication on NT?
I played a lot with ntsec,nontsec,ntea,nontea starting serrvice as
SYSTEM or as administrator

Result is that the SYSTEM user can't access
/home/*/.ssh/authorized_keys[2] no matter the modes or owners, only way
to use pubkey auth is to start the service as the user that wants to
connect, not a real solution..

As anyone got better?

I mean using the OpenSSH distro available now.

Thanks =)

The reason is the restriction for changing user context on NT/W2K.
You can do this only by providing the password of that user, even
if the process is running under LocalSystem account.

I don't understand what you try to say with that sentence.

Mail list page

I had reason to go to the mail list page today (where you go when you click
the "unsubscribe" at the bottom of a message), and the Cygwin link doesn't
work.  I tried several others, and they worked fine.  I was going to send
this comment to "Suggestions", but that link didn't work either <g>.

I'll rectify this.  In the meantime you'll have to make do with using the
cygwin web page:  http://cygwin.com/ .  I would suggest that this is probably
a good starting place for all cygwin inquiries.

I'm not sure what <g> means but if you have found an inoperable link, please
send the URL here.

No, they are using a so-called "subauthentication package". I'm just
preparing one for Cygwin but the information which are provided by
Microsoft are very spare. However, we will be able to login to a
system without a password in future but with substantial constraints,
probably. A logon without password will not be able to connect to network
drives unless somebody can show me how to solve that problem.

But then how can IIS authenticate (in https) using only private key?

Of course they have some special access to some special not documented
API to change active user?

I feared that =(

Thanks anyway for the confirm =)

I meant something like: please don't answer me "just patch, hack,
recompile and you can do it"
The problem with recompiling is that I must use ssh in a system which is
not mine ans they would not accept to use a "ercompiled" version of ssh.
Anyway the problem is at the source of W2K authentication as you said,
so there is no such problem...
