Azure Active Directory integration in MVC

Azure Active Directory integration in MVC

Pre- requisite:

1. Visual Studio 2012 Professional or Visual Studio 2012 Ultimate
2. Identity and Access Tools for Visual Studio 2012
3. Azure Subscription

Step 1:

 You need to create Active directory in your Azure subscription. You need to register your application in azure subscription.
 Active directory is called as tenant. Your users from your active directory(tenant) are able to login to your application.
 other users are not able to login. To make other users access available then you need to implement step 3 as well.
Details explained in following link.

Step 2:

You can achieve following:
 1. Getting full user details
 2. Creating and Updating Users
 3. Getting a list of groups
 4. Updating group membership
Details explained in following link.

Step 3:

 If you want to allow access to other user from your organization. then you need to implement multiple tenant(active directory) in your application.
 So other user will be able to login to your application.
Details explained in following link.

Happy Coding !!

Get users information through active directory

If you have an requirement where you have to read users information from active directory then dot net has provided a dll named "System.DirectoryServices dll ".

Get users information through active directory.

1.You need to add System.DirectoryServices dll reference in your project.

2.Add following code in default.aspx page.
        it automatically finds user name from Page.User.Identity.Name. We have added some properties like: sAMAccountName it only load those properties which we have mentioned in our code.

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.IO;
using System.DirectoryServices;
using System.Runtime.InteropServices;
using System.Security.Authentication;
public partial class _Default : System.Web.UI.Page
    protected void Page_Load(object sender, EventArgs e)
        SearchResultCollection users;
        string loginUserName = "";
        if (string.IsNullOrEmpty(Page.User.Identity.Name) == false)
            loginUserName = Page.User.Identity.Name.ToString().Substring(Page.User.Identity.Name.ToString().LastIndexOf("\\") + 1);
        using (DirectoryEntry Root = new DirectoryEntry())
            //Establish connection to current loged on users Active Directory
            using (DirectorySearcher Searcher = new DirectorySearcher(Root))
                //Start at the top              
                Searcher.Filter = "(&(objectCategory=person)(anr=" + loginUserName.ToUpper().Trim() + "))";
                Searcher.SearchScope = SearchScope.Subtree;
                //Start at the top and keep drilling down
                //Load User ID
                //Load Display Name
                //Load Users first name
                //Load Users last name
                //Users Distinguished name
                //Ext. Number
                //7D Phone Number
                //Cell Phone Number
                //Cell Phone Number
                Searcher.Sort.PropertyName = "sn";
                //Sort by last name
                Searcher.Sort.Direction = System.DirectoryServices.SortDirection.Ascending;
                users = Searcher.FindAll();
                    //Users contains our searh results
                    //If it's zero then no matches were found
                    if (users.Count > 0)
                        //goes throug each user in the search results
                        foreach (SearchResult User in users)
                           // ResultPropertyCollection rcol = User.Properties;
                            ResultPropertyCollection props = User.Properties;
                            foreach (string prop in props.PropertyNames )
                                ResultPropertyValueCollection values = props[prop];
                                foreach (string val in values)
                                    //if (prop=="mail")
                                    //    Response.Write(val);
                                    Response.Write("<br>"+prop + "= " + val);
                        // Store the DataTable in ViewState.
Active directory can provide a lot of information for a user. I have collected some of information which i required for my task.

Happy Coding!!
