I remember reading on this forum about the security of the webservice.

I'm still confused and disappointed that there was no satisfactory answer provided about it.

Problem: most of the SOA applications are Protected applications, i.e. you must sign-in to use it. specially SaaS applications.

Q. Please provide information about how to know which user is logged-in and calling the WS from client side. and how to present user based data. i.e. emails.

Thanks,
Nish.

Nish,

I wrote a blog post on this subject that might be a good starting point for you.

I hope that helps.
