Hi,
We have SG330 Firewall and today I have faced the issue in AD authentication error. When I try to test the connection with the server it show-up Server is down or Unreachable. We have integrated Main AD and back up AD but backup AD connection works fine. Then I have checked with both Clocks, but its fine. We are using Connection Security SSL\TLS (port 636). But I change it to simple then it starts to connect. But my backup domain Connection Security is with Port 636. how it happens.
Please Help to fix this issue.
