ASP.NET Membership - Two providers on site

Question

Hi,

Our site has got two ASP.NET membership providers. The built in one, and a custom one (SqlMembershipProvider.

I am able to log into both no problems, but I don't necessary require the ability to have both logged in at the same time.

The issue I have is as follows:

User "[email protected]" logs into the built in provider. They then navigate to the section of the site where we require the custom provider.

On this page, I can check if they are authenticated, and get their username. I can then get a MembershipUser object form the custom providers GetUser method. (HttpContext.Current.User.Identity.Name)

It is possible (and very likely) that the username "[email protected]" could also exist in the users for the custom provider.

But, I don't want them to be logged in here, as they haven't authenticated against the custom provider.

So, is it possible to check which proivider HttpContext.Current.User was generated from.

Hope this all makes sense!!

Yes, if you notice on the RolePrincipal there is a property called ProviderName.

Typically when people roll their own providers they omit usage of this field.

In your case, simply modify your custom provider to identify itself, if it does not already, and check that property of the user.
