ok, please confirm that you choose "show all fsso logon" on that GUI

if your user not displayed mean you have sth wrong in active directory polling settings

I suggest you to read again the guide

https://docs.fortinet.com/document/fortigate/7.2.1/administration-guide/503764/fsso-polling-connector-agent-installation

if your config is OK, when you logon windows domain computer, user information must be collected by fortigate automatically and displayed on monitor section

Hi @MustphaBassim

Do you have any deny policy as well for those users ? Firewall policies are working from top to bottom. Might be that allow policy is above then the deny policy.

Moreover, check the logs of Fortigate for more details.

you should check that the user you want to block was authenticated as FSSO-Users group

FSSO user must automatic authentication on firewall when the user logging on client PC on domain network without entering user name, password again to fortigate authentication portal.

I think that it;s authenticated with firewall user method, not fsso this case, please re check

no man, you said that you implement fsso , then you have to check that the user you testing that policy is authenticated at right group, you can see at "firewall user monitor" in GUI that if that user is displayed and belong to Fsso-users group.
Anyway you implement fsso using active directory polling or fsso-agent installed on server computers to sync the authentication to firewall?

Hello,

fitting debug here:

diag debug console timestamp enable

diag debug app fssod -1

diag debug app auth -1

diag debug app smbcd -1

diag debug enable

should show you which users are actually picked up.

I do recommend using the Agent based polling instead, leaves the FortiGate free for its firewalling job and is more flexible in terms of understanding logon events.

and another note: the firewall user monitor is important. If the user is not there or not correct, the policy objects WILL not work. First make sure the users are listed. If they are, then your firewall can use these groups in its policies.
