If you are trying to get K2 Blackpoint or K2 Blackpearl working in a one way trust environment using K2′s pass thru authentication there is a blog post here on how to get it to work:

Working with a one-way trust using K2 4.5 with KB001290

I followed the instructions but every time I tried to access the settings page in the K2 process portal (/_layouts/K2/PPManagementConsole.aspx) I would get the error:

Authentication required for session xxxxxxxxxxxxxxxxxxxx

This was because the account(s) running my Sharepoint app pool(s) also need to be in the trusted domain along with the K2server service account.

Hopefully this may help someone if they have similar problems!

When troubleshooting K2 Blackpoint / K2 Blackpearl you run the K2 Server in console mode, this then allows you to see everything thats going on as the K2 server is processing requests. However the text moves quickly so for further analysis you can output everything to a text file by running the K2HostServer.exe & piping it out to a file of your choice eg below:

C:\Program Files\K2 blackpearl\Host Server\Bin\K2HostServer.exe > c:\k2ServerLog.txt

The above will output everything to the root of C: into a file called k2ServerLog.txt
