Getting user's first and last name from AD

I have an intranet site running with windows authentication, and I would like to greet the user with their full name. What's the best way to find the first and last name values entered in the AD database?

I guess it needs a DirectorySearcher object, but my AD knowledge stops there.

You can get the current user's details by parsing their domain name and performing a search for it.  Here is an example - 'sn' and 'givenName' are last name and first name respectively.

<%@ Assembly Name="System.DirectoryServices, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"%>
<%@ Import Namespace="System.DirectoryServices" %>
<%@ Import Namespace="System.Text" %>
<script language="c#" runat="server">
private void Page_Load(object sender, System.EventArgs e)
        string adsPath = "LDAP://server/dc=yourdomain,dc=com";
        //parse the current user's logon name as search key
        string sFilter = String.Format(
            User.Identity.Name.Split(new char[]{'\\'})[1]
        //this is optional, but more efficient
        string[] attribs = new string[]{"cn", "sn", "givenName"};
        using (DirectoryEntry de = new DirectoryEntry(adsPath))
            de.AuthenticationType = AuthenticationTypes.Secure;
            //use explicit only if necessary
            //de.Username = "domain\\user";
            //de.Password = "secret";
            DirectorySearcher ds = new DirectorySearcher(
                attribs, //set this to null to retrieve all attribs
            SearchResult sr = null;
            //this is a workaround for memory leak in v.1.1
            using (SearchResultCollection src = ds.FindAll())
                if (src.Count > 0)
                    sr = src[0];
            if(sr == null)
                msg.Text = "User not found...";
            StringBuilder sb = new StringBuilder();
            //dump everything we have
            foreach (string key in sr.Properties.PropertyNames)
                if (sr.Properties.Contains(key))
                    foreach (object o in sr.Properties[key])
                        //output every item
                        sb.AppendFormat("{0} : {1}<br>", key, o);
            msg.Text = sb.ToString();
<form id="main" runat="server">
Data for user: <%=User.Identity.Name%> <br><br>
<asp:label id="msg" runat="server" />
