This VFS module is part of the samba(7) suite.
The extd_audit VFS module records selected client operations to both the smbd(8) log and system log (using syslog(3)).
Other than logging to the smbd(8) log, vfs_extd_audit is identical to vfs_audit(8).
This man page is part of version 4.14.2 of the Samba suite.
The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed.
