Anonymous API Patterns

2014-06-20 Thread larry mccay
All -

As I begin to add the beginnings of the management API to Knox, it occurs
to me that certain resource URLs will require/allow anonymous access.

For instance, admin/api/v1/version shouldn't require authentication - since
it may be used to determine which contract to use or some other non-request
processing book keeping.

What I have in mind is a scheme wherein a given API service contributor
will communicate the patternsForAnonymousAccess in addition to packages and
patterns that it does today. The base class jersey contributor can noop the
method for backward compatibility.

As the base class jersey contributor loops through the patterns to add
filters for, it will check whether each pattern is a member of the
anonymous access group and if so add an anonymous authentication filter
instead of the one configured in the topology. The anonymous authentication
provider will simply create a Subject with principal of anonymous and no
groups. It will then be up to identity assertion role mapping to add any
groups to the Subject. Something like everyone group would make sense and
could then be used in SLA acls for access decisions.

The rest of the API will likely be protected with acls for role of admin.
The administrator role would need to be added to LDAP groups or also added
through the identity assertion provider based on specific principal names.

I think that this will allow for an API with up to two authentication
levels:
1. the configured authentication/federation provider for the topology that
is hosting the API
2. anonymous access to a subset of the API

thoughts?

[jira] [Created] (KNOX-399) Allow Anonymous Access to Select API Patterns

Re: Anonymous API Patterns

2014-06-20 Thread larry mccay
That is exactly what I am describing.

I'll have to dig into the jersey handoff in order to understand though I
think you are saying that the patterns aren't used to route to any
particular filter chain. Not sure I understand that though given the code
in the jersey contributor base class - it loops through the patterns
creating separate chains. I'm sure it will become obvious when I dig in.

Thanks for the response.

 My first thought is that this is tied up in the issue of removing the
 filter chain definition from the service contributor.
 This has been discussed a number of times including as part of
 https://issues.apache.org/jira/browse/KNOX-177
 Note that I no longer really agree with my proposal documented on the
 related wiki.

 The need for potentially different authentication schemes for different
 URL patterns was one of the original reasons the filter chain construction
 was left entirely up to the service contributor.

 All this being said I believe what you are describing here is a way to
 control which patterns are for anonymous access so in addition to

 public abstract class JerseyServiceDeploymentContributorBase extends
 ServiceDeploymentContributorBase {
   protected abstract String[] getPatterns();
   ...
 }

 you are considering adding

 public abstract class JerseyServiceDeploymentContributorBase extends
 ServiceDeploymentContributorBase {
   protected abstract String[] getPatterns();
 *protected abstract String[] getAnonymousPatterns();*
...
 }

 Am I interpreting your email correctly?  I sort of get where you are going
 but this alone will be insufficient.  This is because of the way we hand
 off to Jersey.  It doesn't matter which chain you come in through as long
 as you have declared the correct packages.  This assumption would need to
 be verified though.
