Bryan Pendleton commented on DERBY-866:
---------------------------------------

Thanks Rick, lots of good material to chew on there.

Using a trailing colon to enable special behaviors seems pretty subtle, syntactically. I can
imagine
overlooking it when proof-reading somebody else's configuration quickly.

I agree with you that it will start to get confusing when I have a username/password pair
in each
database, and am not sure which username/password is being used when. Not sure I have a
better answer for the problems you pose, though.

Overall, what you propose seems useful to me. The biggest problem I was worried about
was that there would be some "special" database with a "special" name that was unexpected
and out of my control, and I would overlook it since it was created automatically by the system
and I didn't realize it was there. Having a way to point at one of my own, existing databases
seems to address that problem adequately, to me.

> 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.
