I am having some difficulty configuring our PAN environment to take advantage of the User-ID feature.
The current configuration is as follows:
I can manually update the PAN200 with user / IP data using the vb scripts provided by PAN (nickp) and via the RESTful API and the data is distributed to the receiving firewalls. However, I would like to use the WMI client probing feature and was under the impression that if the receiving firewall doesn't have a mapping for a given IP address it would request the UID Agent to collect it on it's behalf. This doesn't seem to work. I have entered appropriate credentials within the WMI configuration page on the PAN200 and have enabled 'Client Probing'. I have run the command "wmic /node:remotecomputer computersystem get username" from my desktop with the credentials entered in the WMI section for a given remotecomputer and I get a result so I am confident the user permissions are correct.
Where have I gone wrong? What changes are necessary? Which logs should I investigate?
Any assistance would be welcome.
So, the probe interval is 20 mins and the user identification timeout value is 45 mins for WMI settings under the User Mapping. To give you an idea of the size of the environment, there are around 2500 Windows clients.
I know WMI is not working as the PAN200 device is not updating it's mapping information i.e. it shows only the mapping information for the user / IP address mapping I sent to it via the RESTful api:
https://pan200ipaddress/api/?type=user-id&vsys=vsys1&cmd=<uid-message><version>1.0</version><type>update</type><payload><login><entry name="lab\test1" ip="192.168.1.1"/></login></payload></uid-message>
It seems to me that either the receiving firewalls are not 'asking' the PAN200 to carry out the WMI probe or the PAN200 is unable to for whatever reason. The PAN200 is configured on the internal client network so there isn't an issue with network filtering. I should also state that the PAN200 is only linked to the network using it's mgt interface - there are no other connections.
Thanks for your assistance Panos. The issue is now solved.
It seems that if you enable WMI client probing on the policy enforcement firewalls (i.e. not the PAN200 which is being used as a UID agent) the probes do in fact take place. So it stands to reason that PANOS UID Agent does not carry out a WMI probe on behave of the policy enforcement firewalls. This behaviour is not very well documented.
