Re: [equinox-dev] authentication vs authorization

Okay, this clarifies a lot. So, you want a user preference type service to store the authentication information for remote machines, and you want to be able to authenticate users locally. UserManager should be able to provide the backend for the latter. Some of the features of JAAS purport to supply the front end for the latter. I would also like to see a nice user facing security model for Eclipse that would make sense for users. The simplest version would be that a user simply logs in and there is a property or service or extension that tells who the current user is. I am particularly interested in such a user facing model so that it could be tied into ConditionalPermissionAdmin using a new Condition implementation.

There is a nice description of ConditionalPermissionAdmin in the OSGI R4 specification, which can be downloaded from the www.osgi.org site. (Follow the OSGi Technology link.)

Hi Ben,

Well, one simple use case of immediate interest to ECF users

1) user starts Eclipse
2) they want (via ECF) to be automatically connected to their 3 (n)
IM/other remote accounts upon startup
3) Each of these accounts has a) service type/protocol (URI) b)
username; c) password and/or other credentials

Think GAIM.

And each of the n accounts that are connected really *should*, it seems,
be determined by some notion of an authenticated platform user...with an
associated user-specific secure datastore rather than have it be shared
for every person that starts Eclipse and runs ECF plugins (i.e. which
would be the case if ECF just stores all of this info in the preference
store).  Of course it's not limited to ECF plugins...team plugins/CVS,
soap services plugins, etc., etc.

If there are docs on the ConditionalPermissionAdmin I can/will take a
look at them...I was unaware of it...but does it deal with the (pretty
mundane I know) use case above or is it intended for something else?
