Here are https://ping.force.com/Support/PingIdentityArticle?id=kA340000000GsCmCAK&categ=All some detailed steps if it is not a simple configuration issue:The first step in troubleshooting a Key Distribution Center(KDC) connectivity problem is to make sure that a KDC is being properly selected. There are two options: 1. If no KDC name is specified, the setup process will do a server(SRV) record lookup in domain name services(DNS) to find an authoritative KDC for the specified Realm. If the SRV record lookup fails, an error message will report that a KDC was not found. This method cannot be used if the SRV lookup will fail or if the lookup is likely to return a server which is not actually reachable. 2. If a KDC name is entered, no DNS SRV lookup will be done. Instead the fully qualified domain name(FQDN) will be constructed using that name as machine name and the Realm value as the DNS Domain. A normal lookup will then be done to resolve that FQDN to an Internet Protocol(IP) address. That lookup will be satisfied by a record in /etc/hosts or, if that doe
