[jira] [Updated] (DERBY-866) Derby User Management Enhancements
[ https://issues.apache.org/jira/browse/DERBY-866?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rick Hillegas updated DERBY-866:
--------------------------------
Attachment: derby-866-24-aa-dboMustTurnOnSecurity.diff
Attaching derby-866-24-aa-dboMustTurnOnSecurity.diff. This patch forbids another weird Derby behavior when NATIVE authentication is involved. I am running tests now.
The weird behavior is this: If authentication and authorization are not on, then any legal user can hijack the database by turning them on and specifying credentials which lock out everyone else. This patch prevents an insider from using NATIVE authentication to do this. Because of backward compatibility, I am reluctant to close down this behavior for other authentication schemes. But since NATIVE authentication has not gone GA yet, we have the opportunity to make it behave better.
More exactly, this patch enforces the restriction that only the DBO can turn on NATIVE authentication.
We can relax this restriction in the future if someone comes up with a supporting use case. However, right now this looks like a security hole to me.
Touches the following files:
-----------
M java/engine/org/apache/derby/catalog/SystemProcedures.java
The new check to let only the DBO turn on NATIVE authentication.
-----------
M java/engine/org/apache/derby/loc/messages.xml
Slight rewording of an existing error message so that is can be re-used for this check.
-----------
M java/testing/org/apache/derbyTesting/functionTests/tests/lang/NativeAuthenticationServiceTest.java
New test case to verify the new behavior.

> 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.
