Barracuda Web Filter – Not Displaying Usernames

KB ID 0001296 


I installed a Barracuda Web Filter 410 hardware appliance last week for a client on a 30 day trial. It was in ‘inline’ mode in front of their firewall and was happily logging all web activity and sites that were getting blocked. The problem was when you looked in the log this is what you saw;

Barracuda no usernames

With other vendors you simply need to put an agent in to fix this, and as it turns out Barracuda is no different.


I went onto the web and tried to get the agent, but you can download it straight from the appliance. (Users and Groups > Authentication Tab)

Download Barracuda ADAgent

To proceed you need to add your domain controllers onto the Barracuda

Barracuda Ad AD Authentication

Note: You will need a domain account (a simple domain user is fine, it does not need any additional rights). Here I’m connecting via 389, if you wanted to connect with LDAPS see the following article.

Windows Server 2012 – Enable LDAPS

Once you have installed the ADAgent.exe, (on each domain controller), run it and enter your domain user account, and test it connects properly.

Setup Barracuda ADAgent

Then add in your Barracuda device.

Add Device to Barracuda Agent

Note: Theres nothing else you need to do in the agent but while you are setting it up I suggest you see the logging level to debugging.

Now, before the successful logon events can be uploaded to the barracuda, the domain controllers need to have auditing enabled for;

  • Audit account logon events (success)
  • Audit logon events (success)

Set this in the ‘local security policy’ on each of the domain controllers, (administrative tools local security policy).

AD Agent Audit Policy

On the Barracuda itself  you now have to register the agent for each one you have deployed, after a few minutes they should ‘go green’ this is done on the same tab you specified the domain controllers.

Register ADAgent Barracuda

You now need to wait until your users have logged off and back on again before it starts logging properly so leave it a while to slowly populate.

  1. Keep in mind this doesn’t work for RDS or Citrix. This is why we moved away from Barracuda for web filtering. You have to run in hybrid mode in order to do this.
