Why do I have to log in twice in an Azure deployed LightSwitch application?

Question

I've published a VS 11 LightSwitch app to Azure. When I navigate tot he site, I receive a "Windows Security" dialog. If I enter the credentials for one of the users in the application, the dialog closes, and then I get the application log in screen.

The Windows Security dialog.

The LightSwitch log in screen

Why do I have to enter the credentials twice? I only want users to log in via the LightSwitch log in screen.

Any info is appreciated.

Answer 1

Are you mixing windows and Forms auth security?

Which one do you want?

I think you only need to turn on Forms auth security inside LightSwitch and turn off Azure security... unless you want windows security. In that case I think you set LightSwitch to use windows security and then it should just let the person in if they are authenticated.

Thanks Michael,

I only want Forms authentication. Where do I turn off Azure security, for this particular app?

Hello,

I have exactly the same problem. Someone knows how to solve it?

Thanks and regards

Answer 5

For the life of me I can not remember what I did to resolve this. I may have went as far as to delete the cloud instance, and then recreate it.

The latest version of the application I have deployed is created and deployed using VS 2012 RC. I could very well be that because I went from the beta to RC that may have solved it. 

Sorry about that Ramon,

Answer 6

Whats the web.config look like?

Answer 7

Hello,

I tried several things and I can not figure it out.
I compared the web.config file with another generated a new project and is similar. I have also tried to eliminate deployment through the azure portal to return to be generated when publishing from LightSwitch and continue with the same problem.

If anyone has any ideas I'd appreciate it. Deputy web.config detail for what it is:

Answer 8

I might be parent node IIS config settings that turning on windows auth.  Walk up the node tree from the site up and double check windows auth is disabled.

Answer 9

Hi all,

I finally found the solution to the problem. After reviewing over and over all LightSwith configuration files and IIS configuraion, the problem was in my code.
We briefly explain where the problem was: I use the Application class to store some global variables that I use in my application. I also use the method "Application_Initialize" to initialize its values ​​with a code like this:

static unidad_medidaItem _unidad_medidaGlobal = null;

partial void Application_Initialize()
{
      _unidad_medidaGlobal = Application.Current.CreateDataWorkspace().SUMOData.configuracion_global_SingleOrDefault(1).unidad_medidaItem;
}

As you can see what I do is access a table to keep taking a value in a variable.

The problem comes because this method is executed before the LightSwitch forms authentication, and as yet does not have a user to access the data, this causes display the dialog windows style user validation. After running this code already appears in the form authentication that we have configured in the application for access.

If I comment this code, the validation is working properly.

Thanks to all that you have tried to help me and I hope this will help someone too.

regards,
