(Another) Kerberos / ActiveDirectory problem

Hi all,

It seems like a lot of people are having problems with Kerberos / AD integration, so at least I'm not alone! It's very frustrating as there just aren't any good howtos that I have found, it'd be great if we could get some decent documentation around this. I'll keep a track of all the errors I've been receiving and how I've solved them (if I manage to solve them!).

Problem is as follows:

Alfresco version: 3.0.0 (b 1164) schema 131
Machine running Alfresco: Windows XP SP3 (Name: neptune)
Primary Domain Controller: Windows Server 2003 SP2 (name: server2k3)

I have followed the instructions on: to the letter (twice in fact). I have also switched on debug logging for smb.protocol by editing C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\classes\ and uncommenting the following lines:

# CIFS server debugging

The server starts with no errors. Upon attempting to connect to the network share \\neptunea\alfresco I am prompted for a username and password. When I enter my normal windows username and password the following errors appear in the tomcat console

Hope someone can shed some light on this, it seems amazing that this is so difficult!

Does anyone actually have Kerberos / ActiveDirectory setup and working correctly? If so, would you mind letting me know what version / operating systems / configuration files are required.
