Rampart: Unability to specify custom implementation of PolicyBasedResultsValidator

[Narayan Dhillon <Na...@vocalink.com>]

Hi,

 

Cert validation is important part in WS-Security and different
organizations have different rules for that, and that could be fulfilled
by ability to have custom implementation of PolicyBasedResultsValidator.

 

All the documentation and intention in the Rampart code seems to suggest
that org.apache.rampart.PolicyBasedResultsValidator.verifyTrust() method
could be overridden in custom implementations. However currently
PolicyBasedResultsValidator is hard-wired into RampartEngine; which
makes it impossible to override unless RampartReceiver & RampartEngine
are overridden as well.

 

I can think of 2 options -

(1) Ability to provide custom policy validation by sub classing
RampartReceiver, and then RampartReceiver passes it to RampartEngine.
This is same way as done in Old config based rampart as verifyTrust()
method could be overridden by extending WSDoAllReceiver.

 

(2) Using Rampart config to specify PolicyBasedResultsValidator class.

 

Option (1) is fairly easy to implement and will also make Rampart
capability backward compatible with old Rampart.

 

I'll highly appreciate if development team could please comment on this?

 

Regards, Narayan

Hi Narayan,

Do you want to be able to validate complete results? Or only cert 
validation? If so I think we can give a solution where you can specify 
the Trust verification separately through the configuration.

We can use a callback approach in this case as well where the callback 
handler interface that you will have to implement will have a method 
that accepts the cert and RampartMessageData instance and can return 
whether validation is successful or not.

Thoughts?

Thanks,
Ruchith
