Subject [jira] Closed: (GERONIMO-2687) All "default" Subjects should be obtained by logging in to a realm, not constructed explicitly
Date Sat, 09 Jun 2007 17:52:25 GMT


David Jencks closed GERONIMO-2687.

       Resolution: Fixed
    Fix Version/s: 2.0-M7

Rev 545781.

This is big change and most likely has caused other problems, lets deal with them in other
Other changes in this commit:
- new server-security-config module to hold the security stuff you want to change, whereas
the j2ee-security module holds the stuff you probably don't want to change (including all
the classes).  This makes it easier to swap out the configuration for something for your instalation.

- fixes a lot of security bugs I've lost track of.  One notable one is mdb run-as handling
which wasn't working at all.

> We have several places where we just construct a Subject for a default principal or some
such.  This ties us to some very restrictive assumptions about what a principal is that are
incompatible with e.g. triplesec.  Also it separates security management into maintaining
the login backing store (e.g. ldap) and maintaining the deployment plan. 
> Instead, all these subjects should be obtained by logging into a realm.  To do this we
need way to supply the appropriate credentials.

> that appropriate bits can use to get the subject they need.  The normal implementation
can store credentials for the ids and log in to the realm indicated.  We can have a backwards-compatible
implementation that constructs the subject as is done currently.
> Even better would be to have this accessible only through having some permissions.  However
this would require starting the server to require credentials.  I'm not sure how to implement
that or if it would have widespread support.
