Rick Hillegas commented on DERBY-866:
-------------------------------------
Thanks for reading the spec, Dag. Some responses follow. I will incorporate
your suggestions into the next rev of the spec:
1) I can see the value of warning users that their password's lifetime is
running out. How about:
a) Raise a warning if the password will expire within a week.
b) Raise an exception if the password has expired.
2) I will try to describe the bootstrapping mechanism better in the next rev of
the spec. The idea is that the bootstrap credentials are supplied in the
connection arguments when the database is created. If the database is being
newly created, then we just trust the bootstrap credentials.
The credentials could be supplied by the URL or in the Properties object which
accompanies the connection attempt or in the DataSource. Derby will internally
call createUser() to persist credentials for the DBO when the database is
created.
It is true that the current JDBC connection methods suffer from the String
vulnerability described by the link above. I expect that the JDBC expert group
will address this vulnerability in JDBC 4.2. In Java 8 I expect that users will
be able to state their passwords in a safer way.
3) Agreed.
4) Thanks, I'll clean that up.
5) Thanks, I'll add a note about this to the documentation section. SSL is
essential for safeguarding credentials when using the Derby network client.
Thanks,
-Rick
> Derby User Management Enhancements

> Key: DERBY-866
> URL: https://issues.apache.org/jira/browse/DERBY-866
> Project: Derby
> Issue Type: Improvement
> Components: Services
> Affects Versions: 10.2.1.6
> Reporter: Francois Orsini
> Attachments: Derby_User_Enhancement.html,
> Derby_User_Enhancement_v1.1.html, DummyAuthenticator.java,
> UserManagement.html, dummyCredentials.properties
>
>
> 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.
