/*
 * 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.
