[jcifs] Javamail IMAP NTLM handshake

[Luca Dentella]

Good morning,

I'm working on an IMAP client using Javamail (1.4.3) and JCIFS (1.3.13) and
I'm trying to connect to an Exchange 2003 server with NTLM authentication.

I always get the following error message:
"unknown user name or bad password"

I changed users, passwords, domain with no luck...

On the Exchange Server, in Event Viewer I can read the following entry:

EventID 1069, Source IMAP4SVC
SSPI authentication attempt from <myIP> has failed with error 0x80090302.

In javamail forum they suggested me to post here as Javamail uses JCIFS for
NTLM handshake...

The debug session with javamail:

DEBUG: trying to connect to host "mailexch01", port 143, isSSL false
* OK Microsoft Exchange Server 2003 IMAP4rev1 server version 6.5.7638.1
