/*
* This module implements parseable logging for all Samba VFS operations.
*
* You use it as follows:
*
* [tmp]
* path = /tmp
* vfs objects = full_audit
* full_audit:prefix = %u|%I
* full_audit:success = open opendir
* full_audit:failure = all
*
* vfs op can be "all" which means log all operations.
* vfs op can be "none" which means no logging.
*
* This leads to syslog entries of the form:
* smbd_audit: nobody|192.168.234.1|opendir|ok|.
* smbd_audit: nobody|192.168.234.1|open|fail (File not found)|r|x.txt
*
* where "nobody" is the connected username and "192.168.234.1" is the
* client's IP address.
*
* Options:
*
* prefix: A macro expansion template prepended to the syslog entry.
*
* success: A list of VFS operations for which a successful completion should
* be logged. Defaults to no logging at all. The special operation "all" logs
* - you guessed it - everything.
*
* failure: A list of VFS operations for which failure to complete should be
* logged. Defaults to logging everything.
