   Hi Robert
  
   Given your recent interest in the LDAP module, and its significant
   usefulness to the wider community, I think that's good feature to move
   from sandbox to core. Some things that might need doing in that regard
   include checking the forums for past LDAP contributions (to check the
   current LDAP DAO provides equivalent features), a description for the
   reference guide, and a unit test. Re unit testing, the problem is the
   difficulty of needing an LDAP server to respond to the requests. I see
   a few approaches that we could investigate:
  
   - Expect an LDAP server to be running. A Win32 port of OpenLDAP is
   available at http://lucas.bergmans.us/hacks/openldap/. I wouldn't mind
   if it was a prerequisite that the server was already running, with a
   base schema and users already in the directory. In this case we might
   make the LDAP module a separate Maven subproject so that it doesn't
   interfere with core's unit tests.
  
   - Look at Apache Directory Server. Maybe it could be loaded in-memory
   during the test. I haven't looked into it, but this is attractive
   being an all-Java solution. http://incubator.apache.org/directory/
  
   - Review Olivier Jolly's LDAP support classes at

   took a look and they seem interesting - probably worth using in our

   one or two of the key interfaces and not use an LDAP server at all.

Re: [Acegisecurity-developer] Reducing the number of filters needed in web.xml

2005-02-20 Thread Matt Raible
This looks very cool - anything to cut down the amount of XML needed for 
Acegi Security is a good thing IMO. 

I just finished my chapter on security for Spring Live - do you think I 
should scrap the old stuff and update it to reflect this new way?  If 
so, when will 0.8.0 (or will be it 1.0) be released?  I know the answer 
is probably when it's ready, but it can't hurt to ask. ;-)

Ben Alex wrote:
I've just committed to CVS a FilterChainProxy class, docs and tests 
which make web.xml significantly simpler for Acegi Security-based 
applications. It means you only need a single FilterToBeanProxy in 
web.xml, which delegates to your FilterChainProxy. The 
FilterChainProxy is defined like this:

bean id=filterChainProxy 
class=net.sf.acegisecurity.util.FilterChainProxy
 property name=filterInvocationDefinitionSource
   value
 CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
 PATTERN_TYPE_APACHE_ANT
 
/webServices/**=basicProcessingFilter,httpSessionIntegrationFilter,securityEnforcementFilter 

 
/**=authenticationProcessingFilter,httpSessionIntegrationFilter,securityEnforcementFilter 

   /value
 /property
/bean
It's fairly self-explanatory if you think of 
SecurityEnforcementFilter. The first entry matching the request 
pattern is used, and the configuration attributes define the 
application context bean names of filters to be executed. Filters are 
executed in the order they're declared. This really tidies up web.xml. 
The Contacts sample application demonstrates the approach.

On a related matter, I've addressed the IoC container vs servlet 
container lifecycle issue. Now FilterToBeanProxy does NOT call 
init(FilterConfig) and destroy() unless the optional lifecycle 
initialization parameter is set to servlet-container-managed. This 
means the IoC container is preferred for managing the lifecycle of 
proxied filters. I thought this was the right approach given (i) IoC 
containers provide a far richer and more predictable source of IoC / 
lifecycle interfaces than the servlet spec offers; (ii) the parameter 
can be set to invoke the servlet spec lifecycle methods if desired; 
and (iii) most Filters loaded with FilterToBeanProxy should expect to 
be hosted by an IoC container and would probably prefer the richer 
interfaces such a container exposes (certainly all the Acegi Security 
filters use the Spring interfaces and no-op the two servlet spec 
lifecycle methods). I did of course consider just changing the 
FilterToBeanProxy model - and make all delegates implement a 
SimpleFilter one-method interface instead of Filter - but I know 
many people use FilterToBeanProxy for legacy filters and it seems 
desirable to keep this functionality. Any comments are welcome.

Best regards
Ben

Just use a custom PropertyEditor that works at a String level. The 
PropertyEditor would identify name/value pairs, and create its own 
internal Map. The name part of the pair would be a filter bean name that 
could be looked up from the application context (sure, you lose XML 
validation of the beans being present, but it's tolerable compared with 
a more verbose and confusing syntax). The value part of the pair would 
be the filter mapping. The filter mapping syntax is one to consider. 
Most people seem to prefer Ant Paths, so this might be a more suitable 
default (perhaps the only option?) than regular expressions. Remember 
this new class will need to make the decision as to which filters to 
delegate to. Also, I'd vote for it going into net.sf.acegisecurity.util, 
where FilterToBeanProxy is located. What is the consensus?

RE: [Acegisecurity-developer] Reducing the number of filters needed in web.xml

2005-01-25 Thread Carlos Sanchez
To sum up,

I'll create a class called net.sf.acegisecurity.FilterChain, with a property 
called filters.

About the syntax, I looked at map, that would suit here, but Spring 
application context don't allow beans as keys, maybe a lack of
functionality?

If we use this one we lose validation, so another option could be:

bean id=filterMapping abstract=true 
class=net.sf.acegisecurity.FilterMapping
property name=mappingvalue/*/value/property
/bean

bean id=channelProcessingFilterMapping parent=filterMapping
property name=filterref local=channelProcessingFilter//property
/bean

bean id=authenticationProcessingFilterMapping parent=filterMapping
property name=filterref 
local=authenticationProcessingFilter//property
/bean

bean id=filterChain class=net.sf.acegisecurity.FilterChain
property name=filters
list
ref local=channelProcessingFilterMapping/
ref local=authenticationProcessingFilterMapping/
/list
/property
/bean


More verbose, sure, but allows validation and avoids parsing and it's unlikely 
to change from one app to another.
If you are using XML you should avoid parsing text, that's the goal of XML. The 
problem is that Spring DTD is a bit verbose.

There's no strong reason Ray. It's just most webapps will only have one 
instance of each class, so using class is a way of delivering better 
documentation of what the filter is actually doing. This particularly 
helps with support.

Subject: [Acegisecurity-developer] Reducing the number of filters 
needed in web.xml

   

Hi,
I think this was already discussed but I wasn't able to find it.
I'd like to reduce the number of filters in web.xml to just one, say
filter
filter-nameAcegi Filter/filter-name
filter-classnet.sf.acegisecurity.util.FilterToBeanProxy/filter-
class  init-param
  param-nametargetClass/param-name
  param-valuenet.sf.acegisecurity.FilterChain/param-value
/init-param
/filter
And configure the chain of filters in the application context, 
something like

bean id=filterChain class=net.sf.acegisecurity.FilterChain
property name=filters
  list
ref local=channelProcessingFilter/
ref local=authenticationProcessingFilter/
ref local=basicProcessingFilter/
ref local=sessionIntegrationFilter/
ref local=securityEnforcementFilter/
  /list
/property
property name=filterMappings
  list
value/*/value
value/*/value
value/*/value
value/*/value
value/*/value
  /list
/property/bean
Any thoughts?
Regards

+1, especially using the syntax shown above as it's nice and intuitive.

I like the idea as well, my only question is (and I've been wondering
this for a while), why do we target the class and not the bean name?

 init-param
   param-nametargetClass/param-name
   param-valuenet.sf.acegisecurity.FilterChain/param-value
 /init-param

Instead of...

 init-param
   param-nametargetBean/param-name
   param-valuefilterChain/param-value
 /init-param
