samba log

Hi, I can't figure out how to generate this type of log.. I think it is not possible. I have a samba shared folder that people can access via Win2k and etc.. with unique samba user login. Is there a log that can keep track of whatc each person is doing to the shared folder like delete or create file. I know there is a way to keep a log by network id, but the log doesn't tell me much (using %m.log) thanks henry
