Hi Darren - thanks for the reply!
The so-called "normal" logging is working - the problem is it's tragically
incomplete.
We store IP information on the server. In addition, it's not possible to have
security without accountability.
I was able to modify sftp-server.c to our needs, i.e., basically log every
sftp command issued - including the names of the files transferred - tagged
with user name and stored in a seperate log file.
If anyone is interested in what I did I would more than happy to share it -
otherwise I won't bore you to death.
I'm curious about what you needed that wasn't provided out of the box.
sftp-server(8) says about loglevel: "INFO and VERBOSE log transactions
that sftp-server performs on behalf of the client", and setting this in
sshd_config:
Subsystem sftp /usr/local/libexec/sftp-server -f LOCAL7 -l INFO
gives:

Everything you mentioned (user, source IP address, files accessed) is
all there. What did you find missing?
In short, I solved the my problem and thanks!

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
