Na Li commented on SENTRY-2432:
-------------------------------
[~kkalyan] LDAP is not the only way to integrate with Sentry and provide user
account.
In Unix, it is possible to create user "user_1" and "USER_1", and they should
be treated as different user.
You can look at https://issues.apache.org/jira/browse/SENTRY-319, which changes
group name, and make it case sensitive.
> The case of a username is ignored when determining object ownership

> 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.
