Subject [jira] [Commented] (DERBY-866) Derby User Management Enhancements

Rick Hillegas commented on DERBY-866:
-------------------------------------

Thanks, Bryan. I agree that the trailing : is a little subtle. How about making the trailing
token something bigger, like :LOCAL. The system property could then have these legal values:

1) derby.authentication.provider=NATIVE:$credentialsDB

This setting means "Use $credentialsDB to authenticate system-wide operations as well as connections
to existing databases."

2) derby.authentication.provider=NATIVE:$credentialsDB:LOCAL

This setting means "Use $credentialsDB to authenticate system-wide operations. When connecting
to an existing database, authenticate using the credentials stored in its SYSUSERS table."

To address your other point: Derby never automatically creates a Credentials DB. Derby always
uses a database which the application knows about and asked for. The application has to ask
Derby to create the Credentials DB and the application has to explicitly point Derby at that
database. This is a significant way that a Credentials DB differs from the master databases
created by other RDBMS engines.

Thanks,
-Rick

> 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.
