Cannot integrate with AD

SupunD

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.

    Hi,

    What is the firmware version of SG330? Could you please PM me a screenshot of the configurations? Alongside, start capturing access_server.log from the advance console and Test the AD connection. 

    Please refer to, How to integrate Sophos Firewall with AD.

    Thanks,

    Hi,

    sorry for late reply.

    We identified the issue and it's on the AD certificate issue.

    there is another issue after updating MR8, after upgrade it to MR8 it takes few minutes to connect AD users to the domain. when I log in to the PC network icon shows as limited connection after few minutes it became too normal. 

    Before updating to MR8 (Previous MR2) UTM connection shows 200 users logged. but after MR8 it becomes vary. is that the issue?
