Corporate wifi wont connect with AD logins

Hi all

We use fortinet firewall for our wireless and router/firewall

One thing we having issue with for sometime is users are unable to sign into corporate wifi.

They connect to the SSID, it asks for logins then says cant connect to wifi

I think its certificate issue but ive not configured or used fortinet so not sure where to start and what to do!

any ideas?

thanks

Check the RADIUS server (NPS I assume) logs first, if you're using it, otherwise the FortiGate logs would be a good place to start.

I had look at GPO and could not find anything to do with wifi and certificates being pushed out.

What happens is user connects, it asks for logins, they type in they say cannot connect to wifi.

There is some users connected but they seem to be apple devices like ipad, or mac mini, and few windows.

so seems some can access but some cant. At present 90% cant seem to have access. There is plenty of dhcp scope so dont think its dhcp.

The guest network works ok. There is no captive portal. They should just login with AD details and should connect but does not seem to work

I am not on site till tomorrow to test that but can something be run on server or the fortinet controller to roll this out? we get many users with this issues, even users not on same domain( but have logins for the wifi domain they are connecting to) have this issue so it be difficult to do this one by one

Also i have same issue on windows 10 device too
