Subject [jira] [Commented] (DERBY-866) Derby User Management Enhancements
Date Fri, 02 Dec 2011 19:47:39 GMT

    [ https://issues.apache.org/jira/browse/DERBY-866?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13161813#comment-13161813

Dag H. Wanvik commented on DERBY-866:
-------------------------------------

I like the idea of using a dedicated database for *all* the credentials (system level, db
level) and avoid the problem of maintaining two sets.
As for the denial of service attack you mention not being covered in the proposed solution,
 we could require DBO credentials for the system level operations? We do that already for
encryption, upgrade and system shutdown if sqlAuthorization is enabled (DERBY-2264).

> Proposal to enhance Derby's Built-In DDL User Management. (See proposal spec attached
to the JIRA).
> Abstract:
> This feature aims at improving the way BUILT-IN users are managed in Derby by providing
a more intuitive and familiar DDL interface. Currently (in 10.1.2.1), Built-In users can be
defined at the system and/or database level. Users created at the system level can be defined
via JVM or/and Derby system properties in the derby.properties file. Built-in users created
at the database level are defined via a call to a Derby system procedure (SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY)
which sets a database property.
> Defining a user at the system level is very convenient and practical during the development
phase (EOD) of an application - However, the user's password is not encrypted and consequently
appears in clear in the derby.properties file. Hence, for an application going into production,
whether it is embedded or not, it is preferable to create users at the database level where
the password is encrypted.
> There is no real ANSI SQL standard for managing users in SQL but by providing a more
intuitive and known interface, it will ease Built-In User management at the database level
as well as Derby's adoption.
