-----------------------------

             Summary: The case of a username is ignored when determining object ownership
                 Key: SENTRY-2432
                 URL: https://issues.apache.org/jira/browse/SENTRY-2432
             Project: Sentry
          Issue Type: Bug
          Components: Sentry
    Affects Versions: 2.1.0, 2.2.0
            Reporter: Na Li
            Assignee: Na Li


Sentry saves user name associated with a privilege in lower case. And when getting privileges of a given user, the query returns the privileges associated with a user in case-insensitive way. 

Therefore, if there are two users, only differ in case, will have same privileges.

For example:
1) User user_1 is granted privilege "ALL" on a database DB_1
2) then User USER_1 has full access on that database, 

The desired behavior is to keep user name case sensitive.
