SSL Configuration in SOAP sender Adapter.

Hi,

I have one doubts in the sender SOAP adapter.In the general tab of the SOAP sender adapter there are 3 types of HTTP security level -

1) HTTP

2) HTTPS without client authentication

3) HTTPS with client authentication

My doubt is in the 2nd and 3rd . Here we add a new SSL Access point in NWA so that authentication can be done via certificate, but still when I test a scenario I have to give username and password in SOAPUI and without the username and password I cannot test the scenario and there is a authorisation error.

Can anyone tell me the significance of SSL then if we have to give userid and password ?

Thanks
