Hi,
After applied Windows cumulative update KB5004948 in my environment, the Poll Active Directory is appearing the following error:
# diagnose debug fsso-polling detail 1 AD Server Status(err: server can not be accessible):
The Fortigate is running with FortiOS 6.2.9.
I have opened a ticket with Fortinet support, but I didn't receive yet a reply about the solution to fix this issue.
Someone is with this same issue or has a solution to solve it?

We also have the same issue. but still not resolve. Will call Fortinet Support help to check
Same issue here.
When I look at my domain controller security logs it looks like the login ID is not being reported. It just says NULL SID where the userID should be. Like I said problem started after applying July patches to my DC's.
This was fixed in the latest FortiAuthenticator release, so hopefully the same fix will be coming to FortiOS shortly.
Seems like a Microsoft issue to me.
When I look at event logs on domain controller the 4624 events show "NULL SID" as the user now. So FSSO can't really get the info it needs. That's at least what I'm seeing.
After reading this article about changes MS made in the June patch I figured out my issue https://www.bleepingcomputer.com/news/microsoft/windows-10-kb5003637-update-may-block-remote-access-...
I had to patch my FSSO server up to July patch level for it to be able to read remote event logs from my 3 domain controllers which were also at the July patch level.
