Hi,

I need to use DNN authentication from a third party web-application. This means if someone registered on my DNN portal, he should be able to log in to my web-app with his username and password.

Since DNN uses ASPNET membership API, after copying membership and connection string sections to my web-app's web-config I can simply validate username and password with the code below using membership API:

 

 

Do you have any ideas?

Thanks a lot!

bool login = Membership.ValidateUser(username, passw);However this code gives back "true" for all users who is registered on any(!) of my portals, which is obviously not good for me. As far as I know  ASPNET membership API doesn't support multi-portal environment, so I need to find an alternative way how to do this.

Hi Chris,

Thanks for your answer, but going to database level is what I want to avoid if possible. So I checked what's happening when i log in to DNN, you can find code lines like this: (signin.aspx.vb):

objUser = UserController.ValidateUser(PortalId, txtUsername.Text, txtPassword.Text, "", PortalSettings.PortalName, ipAddress, loginStatus)

So there is some kind of API to log in using "portalid" as a parameter. I tried to reference dotnetnuke.dll in my project to call this method, but I didn't manage to write a runnable code. Can you help me in this? Is this a road that is possible to go down?

Thanks a lot!

Also take a look at IWeb. When you install it there is a link to the IWeb client (a windows Forms program) With the client you can log into your DotNetNuke site. The source for everything is available (you can even use the free Visual Web Developer Express products to view and modify the code).

This should provide all the code you need to verify or log in a user.
