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.

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,
