I am designing a web application using the ASP.net MVC framework. I would like to use Windows Authentication and do Role Checks using the Role Manager SQLRoleProvider.
How can I determine the email address of the current logged on user? Is this even possible?
The application will be deployed in a multi-domain intranet, if that matters (which I assume it does).
Thanks for any help!
Here is a sample from some code:
DirectorySearcher searcher = new DirectorySearcher();
searcher.Filter = string.Format("sAMAccountName={0}", _name);
SearchResult user = searcher.FindOne();
string emailAddr = user.Properties["mail"][0].ToString();
You can look up the user's properties in Active Directory. Here is a great article that explains how to do that using System.DirectoryServices and C#:
http://www.codeproject.com/Articles/6778/How-to-get-User-Data-from-the-Active-Directory
In MVC5 application give the action as given below
public ActionResult Index()
{
string name = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
ViewBag.Name = name;
ViewBag.Email = uEmail(User.Identity.Name.Replace(@"YOURDOMAIN\", ""));
return View();
}
Change the YOURDOMAIN to your domain name. And give the uEmail function as given below. Also add the reference to using System.Security.Principal and using System.DirectoryServices.
private string uEmail(string uid)
{
DirectorySearcher dirSearcher = new DirectorySearcher();
DirectoryEntry entry = new DirectoryEntry(dirSearcher.SearchRoot.Path);
dirSearcher.Filter = "(&(objectClass=user)(objectcategory=person)(mail=" + uid + "*))";
SearchResult srEmail = dirSearcher.FindOne();
string propName = "mail";
ResultPropertyValueCollection valColl = srEmail.Properties[propName];
try
{
return valColl[0].ToString();
}
catch
{
return "";
}
}
The asp.net membership services database is just a database, which you can execute a query against directly. I dont think the default membership provider has a way to get the email address however.
