Custom Report and User ID

[ssarcar]

We are running PA 2020 with Software version 3.1.6. We noticed when we run custom report  with user ID , the logs mix-up Source Host address. For example

A week ago I logged in with a computer name Laptop 1 for a day , and past 6 days I logged in with a computer name Laptop 2. This morning when I ran a report with my user ID just for yesterday , I noticed some of the activity on the logs are from Laptop1. Laptop1 was used by someone else yesterday yet PAN is showing I am logging in with Laptop1.

We contacted PAN tech support and they keep saying it is a DNS problem. However we are not noticing any problem with DNS.

To me it seems like PAN is not clearing the cash.

Or a bad User-ID caching/clearing problem ?

Are you using AD to log in? Is it possible that somone is logging into the laptop with a local user account? If that is the case, UserID will track all activity from that device as the source user of the last person that logged into the device with AD. If you were the last person to log in and someone else logs in with a local account, I believe your name will still be in the FW logs. The user ID agent polls your AD servers... If it is still in the AD DC security logs that you were the last person to log into the laptop, that is what the PA Firewall will put in its logs. I would check the UserID agent and the domain controller and see what users are showing up there for that laptop.

If your AD Logs are different than what your PAN agent has or the PAN agent is different than what your PA Firewall is showing, that would be something worth mentioning to tech support. What version of the PAN UserID agent are you running?
