 <p>Your problem is not in the role provider, or the membership system. This system is suitably flexible enough for your needs, and allows you to assign multiple roles to individual users. You can either use a SQL table to store these roles, or you can use Active Directory, AD is probably easier to manage the users with.</p> <p>Your primary problem is going to be how you assign permissions to the fields and other objects. This means you can't just use standard drag and drop web forms, but will have to build your fields dynamically. </p> <p>It's easy enough to check whether a user is in a role, this is a one-line call. But, your roles will likely not be hard coded, so you need a way to store fields and the roles associated with them, and a way to build the fields based on the users privileges.</p> <p>EDIT:</p> <p>Another option is to build the forms as if there was no security, then in your pre-render event go through and apply your security to each field, disabling and/or hiding fields you don't want the users to see. This may require relaying out the fields if you choose to hide them.</p>
