[Samba] Domain account lockout monitoring tool

[Nguyen Trung Hieu]

Hello

I know there is a domain account lockout feature at:

http://git.samba.org/?p=abartlet/samba.git/.git;a=shortlog;h=refs/heads/s4-bwdPwdCount-01

A malicious user can type in incorrect password of any domain users. Then
these users will be lockout (automatically or manually) in short time. Do
we have any tools (equivalent to Event Viewer on Windows Server) for
monitoring these actions (failed/sucsessful login, log off...)

Thanks
