Martin Zaun commented on DERBY-2109: ------------------------------------ Not much to add to the description by Dan of the user-visible changes with NetworkServer shutdown authentication, this is pretty much it. But to restate and summarize: 1) If running derby server without authentication: no backward compatibility issues. (The old command-line usage, APIs, and derby tests continue to work.) 2) If running a derby server with authentication on: a) The command-line usage of NetworkServerControl to shutdown the sever changes: java org.apache.derby.drda.NetworkServerControl shutdown results in an exception: 08004:Connection authentication failure occurred. Reason: Invalid authentication.. The remedy is to provide credentials: java org.apache.derby.drda.NetworkServerControl shutdown -user <user> -password <password> b) The NetworkServerControl API usage to programatically shutdown a server changes: NetworkServerControl nsc = new NetworkServerControl(); nsc.shutdown(); results in a java.sql.SQLException: Connection authentication failure occurred. Reason: Invalid authentication.. The remedy is provide credentials to the NetworkServerControl constructor: NetworkServerControl nsc = new NetworkServerControl("user", "password"); nsc.shutdown(); c) Note that there is an edge case of b), which the current implementation only addresses poorly: NetworkServerControl nsc = new NetworkServerControl(); nsc.start(console); ... nsc.shutdown(); currently fails with above's SQLException. This is because of an asymmetrie we currently have: we don't require credentials when bringing up a server but we do require them when shutting down. There is an easy workaround, however: NetworkServerControl nsc = new NetworkServerControl(); nsc.start(console); ... NetworkServerControl nscauth = new NetworkServerControl("user", "password"); nscauth.shutdown(); d) If users have their own tests that use derby's junit test framework, they'll have to use a test decorator that takes user credential arguments. e) I'm not sure if users can programatically use derby's NetworkServerControlImpl (!) class to shutdown the server, but if so, they'll have to use an instance that has been constructed with user credential arguments, analog to b). One more item is a not a backward compatibility issue: When running with authentication on, I think the server already requires user credential in connection URLs, for example: connect 'jdbc:derby://localhost:1527/;shutdown=true'; fails but connect 'jdbc:derby://localhost:1527/;shutdown=true;user=user;password=password'; succeeds in 10.3 already. I don't have a strong opinion whether the shutdown authentication feature should be bundled with shutdown authorization checks later or not, but it would be nice to have a better solution for 2c). > System privileges > ----------------- > > Key: DERBY-2109 > URL: https://issues.apache.org/jira/browse/DERBY-2109 > Project: Derby > Issue Type: New Feature > Components: Security > Affects Versions: 10.3.1.4 > Reporter: Rick Hillegas > Attachments: DERBY-2109-02.diff, DERBY-2109-02.stat, > derby-2109-03-javadoc-see-tags.diff, DERBY-2109-04.diff, DERBY-2109-04.stat, > DERBY-2109-05and06.diff, DERBY-2109-05and06.stat, DERBY-2109-07.diff, > DERBY-2109-07.stat, DERBY-2109-08.diff, DERBY-2109-08.stat, > DERBY-2109-08_addendum.diff, DERBY-2109-08_addendum.stat, DERBY-2109-09.diff, > DERBY-2109-09.stat, DERBY-2109-10.diff, DERBY-2109-10.stat, > DERBY-2109-11.diff, DERBY-2109-11.stat, DERBY-2109-12.diff, > DERBY-2109-12.stat, SystemPrivilegesBehaviour.html, systemPrivs.html, > systemPrivs.html, systemPrivs.html, systemPrivs.html > > > Add mechanisms for controlling system-level privileges in Derby.
