Installing and Configuring FSSO
Fortinet Single Sign On or FSSO as it is called, is an agent that is installed on a Windows server that monitors log-on and log-off activity on the domain and provides the info to the Fortigate. This allows you to create policies that match Active Directory Groups. Additionally, this will populate the logs with the username instead of just the IP Address.
In 6.2.x, this process was modified and I will touch on it here as well, but expect a separate, in-depth post on it. There are a few ways to do this and I covered one of them on another blog post. In this post, I will cover the FSSO Agent.
Where to Find the FSSO Install
You will need access to the support.fortinet.com
. Once you log in, you will need to..
Choose Download
.
Then choose Firmware Images
Once there, you will choose the Fortigate
on the drop-down. Ensure you click on Download
and then choose the train you have running on your Fortigate.
Choose the specific version you are running…
Once inside the folder, you will see a sub-folder named FSSO
. This will contain all the FSSO files you need.
In most cases, you will use the FSSO_Setup_*_x64.exe
. This file contains the DC Agent. You also have the TSAgent
files which allow you to install on a Terminal Server or a PC that is being shared between users. To download the file, click on the HTTPS
link. Don’t forget to check the Checksum
as well.
Installing the FSSO Agent
Now that we have downloaded the file, we will need to install it.
Here we see the Windows Executable
Choose Next
which you are going to repeat.
Read and Accept (if you do in fact accept) the EULA.
Choose the target directory and click Next
By default, the install will choose Standard
but you will want to change that to Advanced
and hit Next
Choose Install
Ensure that you have the Launch DC Agent Install Wizard
and hit Finish
The DC Agent will see what Domains this server is a member of and will ask you to click on it. In the above Screenshot, the domain is NOT selected. If it was, you would have seen it in Blue
which I did select after taking the screenshot.
As you can see, we have the FSSO installed. It is now ready for you to change the Password
under the Authentication
portion of the screen.
If you want to validate that it is working, you can click on the Show Logon Users
and it will show you what the FSSO is seeing from a logged in user perspective.
The install will discover the Domain Controllers in your environment and ask you to install the DC agent. This will require a reboot.
Creating the Fabric Connector
Once you have the FSSO Agent installed, head back to the Fortigate(s). Go to Security Fabiric
then Fabric Connectors
. Choose Create New
You will need to fill in the following:
- Give it a name
- The IP address of the FSSO Agent we installed (The Windows Server)
- The Password (see above)
- Choose
Advanced
- Select your LDAP server from the Drop Down.
- Choose
Groups
then right click on them andAdd to Selected
- Now you can double check the
Selected
Now you will create a group under User & Devices
then User Groups
.
NOTE: In 6.2 you will be able to use the groups directly in the policy without having to use this step.
As you can see, we are creating a Group
. We need to assign a name to it, then choose the Remote Groups
section and hit Add
. You will need to select the DC and then the groups, similar to what we did in the Fabric Connector side.
Creating the Policy
Now that you have all the pieces in place, we will create a policy.
As you can see, we created a new Policy and under Source, we chose all
and then under the User
tab, we chose the correct group.
You should now see you three policies with your three AD Groups.
