Password protect web service

Question

Hi!

Is it possible to require user name and password for a web service without changing the code for existing web service?

Adding a DLL and configuration would be OK, but I rather not change the web service.

Answer 1

Simplest way is to let IIS protect the folder where the web service resides. No code change required.

Answer 2

Use (Windows - Integrated Windows) in IIS this is the only way to apply authentication without changing a single bit of code. Here is the article also contains other options as well.
