Get more information about current user in windows authentication mode

Question

In an Asp.Net MVC 4 windows authentication mode, is it possible to get more information about current user (like name & family)?

Answer 1

Once you get the username you can use Active Directory API to get other properties of user. You can use the following code for example:

Using System.DirectoryServices;

...

DirectoryEntry entry = new DirectoryEntry("LDAP://DomainName");
DirectorySearcher dSearch = new DirectorySearcher(entry);
dSearch.PropertiesToLoad.Add("displayName");
dSearch.PropertiesToLoad.Add("cn");
dSearch.PropertiesToLoad.Add("department");
dSearch.Filter = "(&(objectClass=user)(l=" + username + "))";
foreach (SearchResult result in searcher.FindAll())
        {
            // Login Name
            Console.WriteLine(GetProperty(result, "cn"));
            // Display Name
            Console.WriteLine(GetProperty(result, "displayName"));
            // Department
            Console.WriteLine(GetProperty(result, "department"));
        }

and this can be the GetProperty method:

private string GetProperty(SearchResult searchResult, string PropertyName)
    {
        if (searchResult.Properties.Contains(PropertyName))
        {
            return searchResult.Properties[PropertyName][0].ToString();
        }
        else
        {
            return string.Empty;
        }
    }

and propertyName can be values like:

• Login Name: "cn"
• First Name: "givenName"
• Middle Initials: "initials"
• Last Name: "sn"
• Address: "homePostalAddress"
• ...
