Users are not getting internet

I have created two different domain as member domain servers in different networks and with different network firewall. We are facing issues that most of the users are not getting authenticated on Fortigate single sign on agent which is installed on both DCs. and thats why they are not getting internet. As we stop the connectivity or tunnel link between these networks, users can access internet.

I have two networks and i have two domains with server  2003 and another with 2012 R2 server. We are using Fortigte 100D firewall.

As you have stated this is something very specific with your Fortinet appliance. I am not sure how much assistance you will get here unless someone has experience with this SSO feature as well.

I would suggest checking the Logs on the DC's and also the Fortinet box as well to see what is being blocked.

I would also recommend using something like Wireshark to see the packet captures for a workstation when the SSO is enabled.

I have 100D. Could you share the Fortigate config ? I can have a look what is denying access to internet.

I have configured deny rules on both sides of network firewall, not to logon on remote Domain server. Only logon to local domain server. users who are facing issues regarding internet, they are logging on to remote domain server. i.e. user from 172.25.X.X subnet is logged on to 172.21.X.X domain server.
