Credential Phishing with credential submission method as Use Domain Credential Filter

[bgunasekar]

Hello team,

Customer has configured Credential Phishing with credential submission method as Use Domain Credential Filter and it does not work
The user id agent is configured on the writeable domain controller
But according to the below document to enable credential detection, must install the Windows-based User-ID agent on an RODC
https://www.paloaltonetworks.com/documentation/80/pan-os/pan-os/threat-prevention/configure-credenti...

Wanted to verify if RODC is mandatory to enable credential detection or will it work on writeable domain controller

The output of show user user-id-agent state SVR-DC2 is attached

Kindly verify regarding the same 

Regards

Banu Priya

When you asked the question, I was thinking the RODC was just a suggestion for security reasons, and the link you tagged actually states as such:

https://www.paloaltonetworks.com/documentation/80/pan-os/pan-os/threat-prevention/configure-credenti...

"Installing the User-ID agent on an RODC can be useful for a few reasons: access to the domain controller directory is not required to enable credential detection and you can support credential detection for a limited or targeted set of users. Because the directory the RODC hosts is read-only, the directory contents remain secure on the domain controller."

Did you get your issue resolved?

I'd like to know the same, for I'd like to implement but I don't want to set up an RODC for the sole purpose of supporting this.

Have you got answer for this ?

Unfortunately for this feature to work an RODC is required. Starting from windows server 2012 (or maybe even 2008) the password hashes are not readable from an AD joined server and not even on the domaincontroller itself - even obviously the password hashes are available there. The only way to read these hashes is on an RODC.

Yes, I tested the same configuring RODC when it was not working on AD. It worked on RODC only.
