Subject [jira] [Updated] (DERBY-866) Derby User Management Enhancements
Date Thu, 01 Dec 2011 17:26:40 GMT

     [ https://issues.apache.org/jira/browse/DERBY-866?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Rick Hillegas updated DERBY-866:

    Attachment: UserManagement.html

Attaching a first version of a functional spec for NATIVE user management. This is an attempt
to capture the discussion so far. Having a concrete proposal in front of us may help move
the discussion forward. Your feedback is appreciated.

The following topics need more discussion:

1) This version of the spec does not address the issue of system-wide credentials. I will
post a follow-on comment soon which tries to move that discussion forward.

2) This version of the spec phrases password procedure arguments as CLOBs in order to address
the Java vulnerability described here: http://securesoftware.blogspot.com/2009/01/java-security-why-not-to-use-string.html
An alternative approach would be to introduce a new Derby datatype corresponding to char[].
Other suggestions are welcome.

Thanks in advance for reading this spec.

> 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, 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.
