Multiple domains on PA

L4 Transporter

Hello ,


We have integrated already the AD ( 3 Servers for redundancy)

The User id we are using is the default one which is on the PA FW


The domain is  . The setup is working .


Now we are building an entirely new domain called .   migration may take time


There is no trust and the forest is different .  


So is it possible to have two different domain from two different forest . ?  

What is the recommendation ?


and is it possible to have user id agent for this new domain on PA or we have to install it on AD server ?


From my view it is more complex to have both but the catch here is that domain abc is same so i need to know what are the limitations of using two different domain


one is to have to add it in each policy where old one is being used ?

When you have to have information from multiple domains it's best to simply utilize the user-id agent installation for each domain and pull the information into the firewall from the agent instead of the integrated agent. 

what are the limitations of installing an Agent software on AD member .


This is a risk to install on AD 



Last week I have worked in the same case, of multiple domains.


If you don't use the User-ID Agent and configure multiple domains, perhaps you will have inconsistent domain issues. Some users will be authenticated with the NetBIOS (netbios\user) and some others with the FQDN (fqdn\user). 


If you don't want to install the agent on the AD server, you can install it on another computer. It is gonna work. If you decide to install the agent on the AD Server, the Agent will have access to all Security logs of the AD, but the Agent is gonna filter the logs based on what it needs to UserID. 


My recommendation is to install it. 


I hope it helps!



Is it possible to run two agent from same server? Or i want to add multiple domains in same agent. 



I didn't see any deployment in where 2 agents are on the same server. You install one agent, and that agent can monitor up to 100 domain controllers. If you want redundancy, you can install another agent, but on a different server.


I hope it helps!
