Windows + Custom Security hybrid??
 
We have an ASP.Net 1.0 application that has a proprietary database with role
information in it. The site is configured to use Windows authentication,
then it uses your Windows ID as the key to load your role information and
store it in a custom object along with some other user attributes. Now I
need to implement this same functionality in ASP.Net 2.0 with Membership and
Roles Providers, and extend the Membership User to add the extra attributes
for the user. I'm not quite sure where to start with this one though...

One of the keys to the current (as well as new) implementation is that all
the information is loaded behind the scenes and the user never has to go
through a sign-in process.

I need to get the Windows identity because that is going to be the key for
loading the extended user attributes as well as role list, but I need to use
"custom" membership and role providers (I think).

Your suggestions are appreciated!
Chris

RE: Windows + Custom Security hybrid??
 
Hello Chris,

From your description, you have an ASP.NET 1.1 application which use
windows authentication and does authorization based on the roles of each
windows user (access control check in application), also each user has some
application specific data associated with him. Currently, you're going to
upgrade the application to ASP.NET 2.0 and want to utilize the new
membership/role provider features to do the same task, correct?

Based on my understanding, you could reimplement the security mechanism in
ASP.NET 2.0 through the following approach:

** still configured IIS to use intergrated windows and make ASP.NET use
windows authentication.

** and the role based <authorization> setting still remain the same(define
role based acccess control for individual pages or sub directory...)

** change the application to use SqlRoleProvider so that we can store our
custom roles for windows user(based on windows username) in SqlServer
database.

here is a good blog article(from scottgu's weblog) which has demonstrate a
typical sampe application similar to your scenario.

In addition, since you mentioned that you also want to add some additional
cuatom datas associated with each user, you can consider use the Profile
service in ASP.NET 2.0 whicn can help store some per-user specific data and
is also provider based(default provider is sqlserver provider).
