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,

> 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.
