Hi,

I am trying to use active directory search. In my local system I am getting the proper output, but when I am hosting it I am getting run time error. The code I am using,

Config:

C#

<connectionStrings>
	  <add name="ADConnection" connectionString="LDAP://gar.corp.intel.com"/>
  </connectionStrings>


<system.web>
    <compilation debug="true" targetFramework="4.0" />
	  <customErrors mode="Off"/>
	  <identity impersonate="false" />
    <authentication mode="Windows">
      <forms loginUrl="~/Account/Login.aspx" timeout="2880" />
    </authentication>

My Code:

C#

protected void btnSubmit_Click(object sender, EventArgs e)
        {

            using (HostingEnvironment.Impersonate()) {

                string connection = ConfigurationManager.ConnectionStrings["ADConnection"].ToString();
                DirectorySearcher dssearch = new DirectorySearcher(connection);
                dssearch.Filter = "(sAMAccountName=" + txtusername.Text + ")";
                SearchResult sresult = dssearch.FindOne();
                DirectoryEntry dsresult = sresult.GetDirectoryEntry();
                lblfname.Text = dsresult.Properties["givenName"][0].ToString();
                lbllname.Text = dsresult.Properties["sn"][0].ToString();
                lblemail.Text = dsresult.Properties["mail"][0].ToString();
        }
}

Error Message:

My solution is just a guess, kindly ignore it, if you're sure this requirements are met.

To query the directory you need an user who's allowed to bind to the LDAP tree else the directory server must allow anonymous binds.

While you're debugging your application on your local machine this requirement is full-filled (at least I assume you're using an AD account).
Things might look different for your web server, do you know if it is even member of your domain?

Try the following:

Create a DirectoryEntry

C#

public DirectoryEntry (
    string path,
    string username,
    string password
)

Use this ctor for your DirectorySearcher

C#

public DirectorySearcher(
    DirectoryEntry searchRoot
)

Kindly let me know, if that was helpful.
