Note to self: strtok() eats consecutive field separators so you have to check for that. Maybe that is what you tried to explain to me =)

Done now, in commit 32d9260. This also renames the opencl format and incorporates the same changes in it (including support for etype 17). I hope I did not mess things up, I have tested all moving parts using the sample pcap files.

Next step is to "upgrade" mskrb5 and rename it to krb5pa-md5. And then I'll do an opencl version of it.
