Hello,
    I am working on a website. The front end of the website is in C# and the backend is MS-SQL server. This website is based on the concept of document sharing. In this we have different level of users. These users are added from the website, thus allocating them a userid and password for login on to the website.
     Since its a document sharing site we plan to provide the users with the faciltiy of WebFolders. The concept of webFolder is to provide the user the access to his folder or files on the website/wenserver via this webfolder in the Network places. In other words the user will not require to access the site through the browser only, but also the user will be able to access the files and folders from the webserver as if he is accessing them from his local machine. And do the changes as and when he requires.

   But for this the webserver should give the permission to the webuser to create and update files and folders on the server. How can this be achieved? How will IIS come to know who is permitted what rights or how the IIS will tally the userid and password entered by the user.

     While doing RnD on this topic i came across WebDAV - Web based Distributed Authoring and Versioning in IIS, Digest Authentication, etc. The basic concept of WebDAV and Digest Authenication is understood. But what are the settings required in IIS so that it can tally the userid from the websites database and not from Authentication / domain metabase, which it normally does.

Here is the link which demonstrates what I am trying to achieve.

This link can explain the end result expected. But I feel in order to achieve this there are some setiings required to be done on the webserver... particularly the IIS.
Please can anyone advise me on the above mentioned topic.

Thank you in advance.

SuhelAhmed.
