Subject Re: -1 Against CLEREZZA-479 commits (was Re: logging in with undereferenceable webid)
Date Wed, 11 May 2011 06:57:43 GMT
I can confirm that I now longer have all permission when using an webid that
cannot be dereferenced or where the key in invalid. In both cases I don't
get an error message but seem to be user anonymous. So I suspend my -1 at
the current stage.

Still I'm sceptical about the current partial solution of the issue. I'm
puzzled by the creation of a test suite requiring such massive changes to
the system under test. I understand a test-suite might require adding some
hooks to the tested system, but here it seems a major redesign is being done
to the whole authentication system for clerezza to be testable with the
suite being implemented. I don't think I'm opposing to this changes but I'd
like them to be under smaller issues describing their scope.

Question regarding the latest commit:
Implementation of AuthenticationMethod can now add principals to the
subject, I assume that with this one can log-in with multiple authentication
methods to gain more permission (e.g. standard set of permission from the
webid, occasionally entering password for admin rights), what I don't
understand is why the implementation of AuthenticationMethod remove
principals (the anonymous principal) that is already associated to the

I'm looking forward to a documentation of the test suite. I'd recommend to
use clerezza commands rather than felix-commmands with :f

What does this mean? starting the first of the bundles above?

Well, I think this occurs when acting as client. Afaik we rely solely on
traditional PKI with jvm CA configuration there (I have some code somewhere
to turn this verification off, but obviously this isn't a real solution)

I'm not sure, this sounds like something which should be part of clerezza
rather than an optional test-suite

Haven't been using the test-suite yet, is it documented somewhere?

 It is working now. Thanks for pointing out the issue.

sure, but having small issues (as well as competence with the source-control
tool used) allow to easily revert to last approved version while the issue
is being solved.

You mean I'm obviously lacking work if I have time to complain about a
blatant security whole?
