Using the troubleshooter i notice that its show message that Active Directory servers are not available. Under the Identity stores when i check on the connection status it shows disconnected. When i click on Test connection it shows successful. This ACS is a secondary. It has happened before and i removed it from the ACS cluster, rebooted it and rejoined it. Ran test connection and it showed "CONNECTED". Now it keeps showing disconnected. Before i involve my AD guys i just wanted to find out if there is a known issue.</P><P></P><P>Thanks,</P><P>Q</P> Mon, 11 Mar 2019 00:51:29 GMT https://community.cisco.com/t5/network-access-control/acs-5-1-with-ad-status-is-disconnected/m-p/1620729#M295919 hogoqo 2019-03-11T00:51:29Z Re: ACS 5.1 with AD - Status is Disconnected https://community.cisco.com/t5/network-access-control/acs-5-1-with-ad-status-is-disconnected/m-p/1620730#M295925 <HTML><HEAD></HEAD><BODY><P>Check your clocks on the ACS appliances or VMs are synced with the AD servers.
