Hey Brian,
I did this years ago at a previous job and as I remember, you will need to create an account for CF to run under. This account will have to exist in the NDS with the same password. With CF set to run under the account, you should then be able to use a standard UNC to access files with <cffile> and such. I believe at the time that not all CF tags supported UNCs so certain functions wouldn't work. The syntax was just <cffile action="read" file="\\novell_server_name\Share_Point\filename.txt"....>
I can remember that for certain situations, I had to login to the server with the account that CF was running under, then I mapped a drive to the UNC that CF would access, logged out, and then restarted CF. The important step in this process was not mapping a drive to a specific letter like you normally would but mapping it to the "blank" option at the bottom of the list. This basically allowed CF to map a drive for it's own use at startup. I don't remember why we had to do this but it may have been so that CF could use a datasource located on another machine.
Hope this helps,
GJ
