Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have various services configured to authenticate against Active Directory. It would be very helpful if they all logged authentication failures, but they don't. This makes debugging even a simple "incorrect password" error very frustrating.

Is it possible to watch in realtime (or later) authentication attempts against AD?

The AD is Windows Server 2003.

From where? A linux workstation or a Windows PC? Have you checked out wireshark? –  wolfgangsz Aug 18 '10 at 17:05
    
"From Where" is irrelevant, but in this example, I'm using a web-based bug tracking program. Wireshark won't help because the requests are encrypted with Kerberos. I need logging. –  Matt Simmons Aug 18 '10 at 17:08
    
Are these services/apps authenticating against your DC(s) or another source? –  jscott Aug 18 '10 at 17:19
    
They are against my domain controllers (is there another way?) –  Matt Simmons Aug 18 '10 at 17:24
    
In the lovely K12-software-world we have software that "does AD" by taking a night export from csvde. –  jscott Aug 18 '10 at 18:04

I'm going to go with the get-eventlog cmdlet in PowerShell. This just dumps the latest entry in the application log:

Get-EventLog -ComputerName foo -LogName application -Newest 1

It just needs tweaking to limit it to authentication events and sources (-source), and to run it against a list of servers. Maybe schedule it to dump in daily or hourly increments (-after [time])? I'm clearly no scripting genius but it's what I've got. ;)
