Error creating ASP web page with single sign on over AAD - asp.net-mvc

Question

I'm struggling with creating an ASP web page with SSO like in this tutorial https://learn.microsoft.com/en-us/aspnet/identity/overview/getting-started/developing-aspnet-apps-with-windows-azure-active-directory but first I got redirected to localhost after deploying the aplication, so I searched and found the solution in ASP.Net redirecting to local host after authentication. But now when I autenticate on the web page I've created I get the next error
[ArgumentException: Format of the initialization string does not conform to specification starting at index 152.]

I've searched if anybody else has got the same error, but not success. I have tried to update nuget packages because it looks like a parsing error with the tokem, but in Startup.Auth.cs sais that authenticationcontext has AcquireTokenByAuthorizationCode deprecated so I tried to replace old code
AuthorizationCodeReceived = (context) =>
{
var code = context.Code;
ClientCredential credential = new ClientCredential(clientId, appKey);
string signedInUserID = context.AuthenticationTicket.Identity.FindFirst(ClaimTypes.NameIdentifier).Value;
AuthenticationContext authContext = new AuthenticationContext(Authority, new ADALTokenCache(signedInUserID));
AuthenticationResult result = authContext.AcquireTokenByAuthorizationCode(
code, new Uri(HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path)), credential, graphResourceId);
return Task.FromResult(0);
}
with:
AuthorizationCodeReceived = async (context) =>
{
var code = context.Code;
ClientCredential credential = new ClientCredential(clientId, appKey);
string signedInUserID = context.AuthenticationTicket.Identity.FindFirst(ClaimTypes.NameIdentifier).Value;
AuthenticationContext authContext = new AuthenticationContext(Authority, new ADALTokenCache(signedInUserID));
AuthenticationResult result = await authContext.AcquireTokenByAuthorizationCodeAsync(
code, new Uri(HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path)), credential, graphResourceId);
return ;
}
But still etting errors. Do you have any idea?

Answer 1

but first I got redirected to localhost after deploying the apllication
You could change the redirect url both in web.config and azure ad application , please follow below steps :
After deploy , you will get the published app url :https://webapplicationname.azurewebsites.net/ , cope the url and modify the web config :
<add key="ida:PostLogoutRedirectUri" value="https://webapplicationname.azurewebsites.net/" />
In azure portal ,click Azure AD blade, click "App registrations" button , find the app you registered . You could find the app by app id(client id) , that could be find in web config:
<add key="ida:ClientId" value="ae7afda3-b24b-42a7-bb14-8d7a08227f66" />
select the app , click "Reply URLs" button , add the published app url(this demo i used webapplication420170330110754 as my app name ,change that to your own app name ) ,click save button:
Now you need to re-publish the app to make the new web.config available .
Edit :
For this error ,please firstly confirm whether you have set the correct connect string . You could find the connect string of azure sql :
Click the connect string you will get that :
