Hello, I'm trying to open a non-technical case to get username and password as suggested in the guide: https://docs.cloudera.com/HDPDocuments/Ambari-2.7.5.0/bk_ambari-installation/content/ch03s02s01.html but when i click on "Create Case" button, I got the error: "Accessing the requested page requires special permissions."   So, anyone can tell me how to contact Cloudera to get the credential needed?   Thank You ...
