Do you think it is possible to include DACS (http://dacs.dss.ca/) as a
authentication adapter (just as it is with Yale's CAS)? There were talks
about the future of authorization in OSS GIS GeoServer
(http://docs.codehaus.org/display/GEOS/Home) which heavily uses Spring,
so it would be natural to use Acegi. On the other hand there is an Open
Geospatial Consortium (OGC) standardising organisation for GIS software
and one of their implementation for security used in demos is DACS. The
problem is that DACS is native application whereas the GeoServer is a
Java webapp.

Maybe you have some ideas or already have head about works between DACS
and Acegi? Do you find it possible to integrate in any scope (just
authentication or maybe even more - to simulate DACS-like authorization
using Acegi)?

Below there is an email on these talks. If it's not clear for you,
please, do not hesitate to ask questions to make it more informative.

Thanks in advance for your help!

Hi all --

Some of this thread was forwarded to me.  As the principal designer and
implementor of DACS, I thought I might be able to comment a little on a few
things that caught my attention.

Jody Garnett napisa³(a):
 I know DACS has been used in an OGC context
Is it an OGC standard or only at OWS as demo?

DACS is not an OGC standard.
It was the subject of three OGC initiatives: CIPI 1.1, CIPI 1.2, and OWS-3.
That work mainly dealt with understanding and solving authentication and
authorization interoperability issues, and some of the results of those
projects were integrated with DACS.  As far as I know, nothing is currently
being done by the OGC with DACS.

 what is the benifit for ACEGI? Ah it is a spring security
 system ...

I don't know anything about Acegi (http://acegisecurity.org) other than
what I have read on their home page, so I really can't comment on it or
compare it with DACS.  But at first glance it looks to me like it is
quite different from DACS in philosophy, implementation, operation, and
feature set.  So I suspect the two systems might be aimed at different
audiences.

As for CAS, it is simply an authentication method, and it is one of many
methods supported by DACS.

Regardless of how authentication is performed, DACS creates a common
internal representation (credentials) which is then exported from DACS
to a client, and later sent by a client to DACS with its request.  In
theory at least, DACS does not care how credentials are transmitted - in
an HTTP cookie, via an HTTP extension header, within a URL, or as an
argument - these are all possibilities.  Clients, which can be
middleware, can ask DACS to decode or export credentials, so a DACS
identity can easily be converted to some other representation, and
importation to DACS from other representations is also possible.
Middleware can ask DACS to create credentials.

The authorization side of DACS is largely separate and independent of
the authentication side.  You do not have to use DACS authentication in
order to use the DACS access control rule-processing engine.

I also can't comment on GeoServer.  I believe that, like Acegi, it is a
Java application, and DACS being C/C++ software, people who prefer a
pure Java solution might not be happy with a system that must use JNI.
Supporting DACS as an optional, third-party component of GeoServer might
be a possibility though.

One other thing that I noticed:
 Do you know if there is any way to integrate Acegi with DACS?

I don't really understand this question because the two systems are
quite different, yet in broad terms, do the same kinds of things.  So
I'm not sure what it would mean to integrate Acegi with DACS.  It might
be possible for Acegi to use DACS's authentication components, its
access control component, or both, but that's probably a question to ask
the Acegi folks. And there's also that pesky pure Java issue.

It might be possible for the two systems to interoperate, but I don't
think that's what you're talking about.

I apologize if I've gotten off topic or confused things.
I'd be happy to answer any questions that anyone has about DACS.

If you can find a means to make java code authenticate against DACS,
then it would be easy enough to write an Acegi AuthenticationProvider
that talks to it.

2007-01-19 Thread Ray Krueger
OK...

Subclassing ServiceProperties isn't going to do any good, because you
don't have access to the HttpRequest.

You can use a PropertyPlaceHolderConfigurer so that your xml looks like...
bean id=serviceProperties class=org.acegisecurity.ui.cas.ServiceProperties
property 
name=servicevalue${serviceProperties.serviceUrl}/value/property
property name=sendRenewvaluefalse/value/property
/bean

And then you can externalize these deployment specific parameters into
a properties file that gets setup at the client site.

We should consider adding a hookmethod into the
CasProcessingFilterEntryPoint to allow customization of how the
serviceUrl is added to the cas redirect.

Oh, and a little tip, you don't have to hard code the http:// part you
can use request.getScheme() (terrible name, go Sun).

Re: [Acegisecurity-developer] Setting serviceProperties in Acegi

2007-01-19 Thread Scott Battaglia
One thing to note is that as a security measure, we never recommend that 
you construct/retrieve the hostname for a service url from the request 
object.  You'll notice that neither Acegi nor the other CAS clients 
allows you have a completely dynamic service url (the CAS client 
requires that you at least specify the hostname). This is because the 
hostname header is generally set on the client side and thus cannot be 
trusted.

Your best bet is as Ben and Ray said, to use the 
PropertyPlaceholderConfigurer.  If you don't want to worry about 
re-generating WAR files for each client you could place the service url 
as a JNDI resource and reference it in the Spring configuration files.

Re: [Acegisecurity-developer] Setting serviceProperties in Acegi

2007-01-19 Thread mario.buonopane
Here is what I did to resolve the problem:

1) I have create a filter that build the servicesProperties url in a
static property. This is the code:
public class CasAcegiServicePropertyFilter implements Filter {
public static String casAcegiServicePropertyValue=null;
private static final Log log =
LogFactory.getLog(CasAcegiServicePropertyFilter.class);

public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain) throws IOException, ServletException {
if(casAcegiServicePropertyValue==null){
HttpServletRequest request = (HttpServletRequest)req;
String cp = request.getContextPath();
if(!cp.startsWith(/))cp=/+cp;

casAcegiServicePropertyValue = 
request.getScheme()+
://+request.getLocalAddr()+
:+request.getLocalPort()+
cp+
/j_acegi_cas_security_check;
log.info(casAcegiServicePropertyValue:+
casAcegiServicePropertyValue);
}
chain.doFilter(req, res);
}

2) I have subclassed ServiceProperties in this way:

public String getService() {
   if(super.getService()!=null) return super.getService();
   else return
CasAcegiServicePropertyFilter.casAcegiServicePropertyValue;
   }

3) I have configured the CasAcegiServicePropertyFilter how first and
serviceProperties with no service url.

OK...

Subclassing ServiceProperties isn't going to do any good, because you
don't have access to the HttpRequest.

You can use a PropertyPlaceHolderConfigurer so that your xml looks
like...
bean id=serviceProperties
class=org.acegisecurity.ui.cas.ServiceProperties
property
name=servicevalue${serviceProperties.serviceUrl}/value/property
property name=sendRenewvaluefalse/value/property
/bean

And then you can externalize these deployment specific parameters into
a properties file that gets setup at the client site.

We should consider adding a hookmethod into the
CasProcessingFilterEntryPoint to allow customization of how the
serviceUrl is added to the cas redirect.

Oh, and a little tip, you don't have to hard code the http:// part you
can use request.getScheme() (terrible name, go Sun).

 Now that I read your email a little more thoroughly, let me take a
 closer look. Personally I've never used the CAS support in Acegi.

 I'll get back to you in a minute or two :)

  Ben answered your original email on this subject...
 
  Is there a reason you cannot use a PropertyPlaceholderConfigurer?

   In using Acegi with Cas in a web application. As you know, I have
to
  set the
   serviceProperties property of CasProcessingFilterEntryPoint to the
url
  that
   CAS will call after authentication. I don't like to set this url
in
   applicationContext-acegi-security.xml but I prefere this
   value Is build automatically. To do it I'm going to extends
   org.acegisecurity.ui.cas.ServiceProperties with a class
   that try to build the service property if is not setted (null)
using
   something like this:
  
  
  
  
 
serviceProperties=http://+request.request.getLocalAddr()+:+request.g
 
etLocalPort()+/+request.getContextPath()+/j_acegi_cas_security_check
  
   (I don't use https in this case)
  
  
  
   What's your opinion?
  
  
  
   Please, any suggestions are welcome.

I also had a similar solution posted back in June 2005, which we've  
been using since then.
