(Updated April 20, 2017, 4:43 p.m.) Review request for Ambari, Di Li, Miklos Gergely, and Oliver Szabo. Bugs: AMBARI-20768 https://issues.apache.org/jira/browse/AMBARI-20768 Repository: ambari Description (updated) ------- A local Ambari user with no cluster roles assigned to it can successfully log into the Logsearch UI. Logsearch service exercises restriction on who can access its UI using a property "logsearch.roles.allowed". This property is a comma-separated list of roles to be allowed access to Logsearch UI. This defect deals with the following issue: 1. If Logsearch service requires that only certain roles be allowed to access its UI, then a local Ambari user with no roles must not be allowed to access the UI. DESIRED BEHAVIOR: ================= 1. A local user with no role assigned to it, must not be able to access Logsearch UI. Note: The description has been updated by removing the aspect of correcting the behavior for Ambari Administrator role for the Logsearch UI. Diffs ----- ambari-logsearch/ambari-logsearch-portal/src/main/java/org/apache/ambari/logsearch/web/security/LogsearchExternalServerAuthenticationProvider.java e23f0a2 Diff: https://reviews.apache.org/r/58493/diff/2/ Testing (updated) ------- The patch *AMBARI-20768.patch* contains the fix for this issue. The fix involves correction in 1 place in the LogsearchExternalServerAuthenticationProvider class. 1. In order to prevent a local user with no cluster roles assigned to it from logging into Logsearch UI, we return *false*. The results of the logsearch tests after applying the patch are shown in the screenshot "all_tests_successful.png" on the Jira. Note: The description for testing has been updated by removing the aspect of correcting the behavior for Ambari Administrator role for the Logsearch UI. Thanks, Keta Patel
