Why both IIS And Asp.net Authentication
<p>I like to share my views(actually confusion) regarding authentication process in asp.net .</p>

<p>There are so many combination of authentication shared between iis and asp.net itself which I need to clarity.</p>

<p>I will appricate you , if you will provide me infomration in detail( if possible with some example and code), as I am not getting proper clarification from so many days.</p>

<p>My questions are :-</p>

<p>1) Why there are two phases of authentication for asp.net application i.e. a)  windows authentication is in both iis and asp.net b) passport authentication is also in both</p>

<p>2) If I had configured Integrated windows authentication in iis and used a)Windows b) Passport c)Forms d)None authentication in asp.net what difference it will bring</p>

<p>3) How to use passport authentication. Even I set passport authentication in iis and asp.net it doesn't given me any configuration screen to configured user for passport authentication.</p>

<p>4) If I am using basic or digest authentication in iis what change it also bring when I use different authentication in asp.net</p>

<p>5) Please provide me information in details , difference between forms and none authentication in asp.net , as i can use same login form for authenticatin in both of this cases, so what change it will bring</p>

<p>Regards,
