NAME
       vfs_full_audit - record Samba VFS operations in the system log

SYNOPSIS
       vfs objects = full_audit

DESCRIPTION

       The vfs_full_audit VFS module records selected client operations to the
       system log using syslog(3).

       In addition to these operations, vfs_full_audit recognizes the special
       operation names "all" and "none ", which refer to all the VFS
       operations and none of the VFS operations respectively.

       vfs_full_audit records operations in fixed format consisting of fields
       separated by '|' characters. The format is:

                     smbd_audit: PREFIX|OPERATION|RESULT|FILE


       The record fields are:

              o   PREFIX - the result of the full_audit:prefix string after
                  variable substitutions

              o   OPERATION - the name of the VFS operation

              o   RESULT - whether the operation succeeded or failed

              o   FILE - the name of the file or directory the operation was
                  performed on


       This module is stackable.

OPTIONS
       full_audit:prefix = STRING
           Prepend audit messages with STRING. STRING is processed for
           standard substitution variables listed in smb.conf(5). The default
           prefix is "%u|%I".

       full_audit:success = LIST
           LIST is a list of VFS operations that should be recorded if they
           succeed. Operations are specified using the names listed above.
           Operations can be unset by prefixing the names with "!". The
           default is none operations.

       full_audit:failure = LIST
           LIST is a list of VFS operations that should be recorded if they
           failed. Operations are specified using the names listed above.
           Operations can be unset by prefixing the names with "!". The
           default is none operations.

       full_audit:facility = FACILITY
           Log messages to the named syslog(3) facility.

       full_audit:priority = PRIORITY
           Log messages with the named syslog(3) priority.

       full_audit:syslog = true/false
           Log messages to syslog (default) or as a debug level 1 message.

       full_audit:log_secdesc = true/false
           Log an sddl form of the security descriptor coming in when a client
           sets an acl. Defaults to false.

EXAMPLES
       Log file and directory open operations on the [records] share using the
       LOCAL7 facility and ALERT priority, including the username and IP
       address. Logging excludes the open VFS function on failures:

                   [records]
                path = /data/records
                vfs objects = full_audit
                full_audit:prefix = %u|%I
                full_audit:success = open opendir
                full_audit:failure = all !open
                full_audit:facility = LOCAL7
                full_audit:priority = ALERT
