Hi All

Is there any way or example how to configure plonePAS to consume a web
service  (in my case JAX-WS via SOAP ) in order to get user details?

This won't be a configuration issue, it will be a coding issue. You don't mention specifically what "consume a web service" means, but you might be able to put together a Scriptable Multiplugin or write your own filesystem-based plugin to do the job.

However, there is one big caveat. Making HTTP calls (or almost any other network request) out of Zope code during the execution of a web request is risky. The executing thread will wait until the external request has been answered, and if for whatever reason no answer is received it will hang forever. There are four threads available in a normal Zope configuration, the fourth time this happens your website will be unavailable and Zope must be restarted. A lot of care needs to be taken to ensure there are sensible timeouts on these external calls to prevent hangs.

You can get around it, though, if you use something like Zasync. A bit heavy-handed, but it's there for ya. :^)
