I would like to enable logging to show each file access and more importantly - delete.
I don't know whether there is any such logging, but there is a lot of documentation for netatalk which I haven't read - you can see the list by typing:
rpm -qd netatalk
If there is no configuration option to produce the logging you need, you can trace the program using strace, or capture the network traffic using tcpdump and analyse it after the fact using wireshark.
