eDirectory on Linux and NCP packet signatures

Hi all,

I have noticed a problem when connecting to a Linux server running
eDirectory if NCP packet signature level on client's side is set to 3.
Strange to see how Windows XP client behaves in such a case: When a
valid user/password (DS dialog) is entered, the client asks again
(Bindery dialog) and then it fails, no drive mapped. It seems that a
connection to the server is established, but it remains in "Not
Authenticated" state (red N / Novell Connections...). Doing the similar
thing on a Linux box with "ncpmount -i 3" command, I'm getting the
following error message:

Unable to negotiate requested security level: Signature level conflict
(0x8861)

Everything works fine for lower levels (1, 2) and I assume that no
packet signing is negotiated. It looks like there is a problem to
negotiate packet signing if forced or it is not supported on server's
side. Very strange...

Thanks in advance,
Pavel

I believe that NCP Packet Signing is not yet supported on the Linux NCP
server.

Re: eDirectory on Linux and NCP packet signatures

Hi!,

We are having the exact same problem. We also have an existing environment with packet signature level 3, and now we want to deploy Linux OES servers and are having problems getting them to use packet signing.

Can we have an official confirmation of this not being supported in the current Linux NCP server?

Thanks in advance,
