I am creating a web application which will make use of the single sign on organisation login feature on .net mvc project.
If the user is on the network I want to allow them to use the application without signing in as i wold be able to get their username with windows authentication.
If external i want to redirect them to the single sign on so they can be authenticated.
However my issue is that even if they are on the network, the application prompts them to sign in. How can i avoid this?
Based on the MICROSOFT DOCUMENTATION:-
Tenant administrators and developers often have requirements where an
application must be restricted to a certain set of users. There are
two ways to restrict an application to a certain set of users or
security groups:
Developers can use popular authorization patterns like Azure role-based access control (Azure RBAC).
Tenant administrators and developers can use built-in feature of Azure
AD.
To implement authentication in your application please refer this Microsoft Documentation:- Configure authentication in a sample web app by using Azure AD B2C.

I am writing an application in C# which would run on a PC and allow a user to login to GCP and manage files there.
I looked at the sample codes on https://cloud.google.com/storage/docs/reference/libraries
The documents show how to use a service account for authentication, but I want to use user authentication.
In this way, if the user do not have permission to say delete data, the application can not do it. If I use a service account, which I don't want.
Is there any way that I use user authentication to log in to cloud storage services?
Is there any sample that I can use for this purpose?
Update 1
My main aim is to develop an application similar to gsutil but in C# and it should authenticate users similar to gsutils.
The same as gsutil, it would be used only by cloud admins who already have access to buckets via gsutils or cloud.google.com
Is the source code for gsutils published? How does it authenticate users?
What you might be wanted to use is this "User account credentials". This at the ends guides you to Firebase Authentication, which supports email and password authentication as well as federated sign in with identity providers such as Google, Facebook, Twitter, and GitHub.
You can sign in users to your Firebase app either by using FirebaseUI as a complete drop-in auth solution or by using the Firebase Authentication SDK to manually integrate one or several sign-in methods into your app. This will be up to your needs and how you want to build your app.
I'm developing an app using ASP.NET WebAPI 2.2 that requires login via Azure AD for which I'm using ADAL/OWIN, but the app must have app specific permissions and roles that can be assigned to users who log in to it (a bit like SharePoint groups). The client can't use Azure AD groups, claims or Azure app permissions to assign rights/create groups as it is set up/maintained by a third party.
So, if the app is authenticating users against Azure AD, am I able to use the SQLRoleProvider to create/maintain a permission set and assign them to users within the app? I've searched for a while and not found anything that exactly fits my use scenario. Currently I'm thinking I may have to roll my own role provider.
EDITED for clarity.
You can use the custom role provider in Azure AD. When used, each user is given a role (or rather, place in a role) at the time the user is granted access to the application. I used this blog post to get started when creating a simple role-based mvc app for a customer:
Azure Active Directory, now with Group Claims and Application Roles.
We used this to separate between regular and admin users of an application we built.
I am working on an ASP.NET MVC application that uses Azure AD auth out-of-the-box.
What I want to do is define custom roles for certain users. For example, mark JohnDoe#contoso as a "Portal Admin" or SarahJones#contoso as a "Site Manager" - I want to do that without messing with AD roles, since I don't have full access to the AD internals.
I am fine deploying a custom DB to contain the roles. Is there a generic solution for this or do I have to implement my custom verification layer?
Update 1: I can deploy a custom role provider and connect it to a different DB, but am wondering if there is a more straightforward way to do this.
If you use Azure Web Apps, which supports ASP.NET MVC then you can use the Azure Active Directory authentication mechanism. Here is a blog post describing how to set it up:
https://azure.microsoft.com/en-us/documentation/articles/app-service-mobile-how-to-configure-active-directory-authentication/
Once you have that, auth will be enabled for your app and you can configure the AAD app in the portal. See this blog post for more details:
http://blogs.technet.com/b/ad/archive/2014/12/18/azure-active-directory-now-with-group-claims-and-application-roles.aspx
To modify the permission levels, you should be able to use role claims. See this example for guidance:
https://github.com/Azure-Samples/active-directory-dotnet-webapp-roleclaims
Accessing the manifest:
Ok, I have looked around and could not find a solution to this problem. I have an ASP.NET web application that is using Windows Authentication.
I have a public web services that I use for an iPad App I have developed. For security reasons all of my Web Services requires a header with login information.
Right now, I have a separate database that I authenticate users from. Its a built in authentication for when my application is installed using Forms Authentication.
What I would like to do is when the user on the iPad logs into the system, it passes the Login and Password to the Web Service in the hearder... which it does now.
But, how can I Authenticate that User and Password against the Active Directory to make sure the user has access?

But, how can I Authenticate that User and Password against the Active
Directory to make sure the user has access?
That's straightforward in c#: Validate a username and password against Active Directory?
More AD tasks in c# (including authentication)

using Forms Authentication.
Based on this statement, it sounds like you have a database of credentials which duplicates credentials in AD? If that's the case, not sure that's a good idea.
And/or it also sounds like credentials which match those in AD are being passed around (possibly in plain text?) This might be a business requirement, but I would recommend that all communication is done over SSL and that the AD accounts belong to a domain setup specifically for this purpose that is not trusted (or only partially trusted) by the rest of the network.
How the sites like stackoverrflow using the third parthy login id(gmail,blogspot), to login the site?
How to do this in asp.net? Give me a idea to implement this in to my application.
i don't have idea from where. I have to start this.
OpenID is a decentralized system for authenticating users via third-party OpenID providers, Google and AOL among them.
http://openid.net/
http://en.wikipedia.org/wiki/OpenID
http://weblogs.asp.net/plip/archive/2008/02/02/openid-in-asp-net.aspx
Its called OpenID, something specifically for asp.net you'll find here
It's OPEN ID. You have a .NET client here. This client will allow you to create open id-enabled applications more easily.
From Wikipedia
OpenID is an open, decentralized standard for authenticating users that can be used for access control, allowing users to log on to different services with the same digital identity where these services trust the authentication body. OpenID replaces the common log on process that uses a login-name and a password, by allowing a user to log in once and gain access to the resources of multiple software systems. The term OpenID can also refer to an ID used in the standard.
