    copied!<p>I would really welcome some help with this issue. We have a php code that works and connects to the LDAP. When I try to connect using VB.NET 2010, it fails to bind with logon failure unknown username or bad password. Below is the connection information. When I talk to the folks who run the ldap server, they say I am binding sucessfully, below is the log file for the sucessful bind? If I continue and try to execute a search I don't get any results. The server is running openLDAP ver 2.3.39 on a linux server, server requires connection on port 636 for secure connection, or 389 for anonymous. </p> <p>using the following imports in code:</p> <pre><code>Imports System.DirectoryServices Imports System.DirectoryServices.Protocols Imports System.Data.SqlClient Imports System.Net.NetworkCredential </code></pre> <p>my connection:</p> <pre><code>Dim dirEntry As DirectoryEntry = New DirectoryEntry("LDAP://xxx.MyDomain.xxx/cn=users,dc=MyDomain,dc=xxx", "uid=my-bind,cn=users,dc=MyDomain,dc=xxx", "MyPassword") dirEntry.AuthenticationType = AuthenticationTypes.SecureSocketsLayer </code></pre> <p>my BindLog:</p> <blockquote> <p>Mar 16 15:10:17 ldap4 slapd[17391]: conn=110556 op=0 RESULT tag=97 err=0 text= Mar 16 15:10:17 ldap4 slapd[17391]: conn=110555 op=0 BIND dn="uid=my-bind,cn=users,dc=myDomain,dc=xxx" method=128 Mar 16 15:10:17 ldap4 slapd[17391]: conn=110555 op=0 BIND dn="uid=my-bind,cn=users,dc=myDomain.xxx" mech=SIMPLE ssf=0 Mar 16 15:10:17 ldap4 slapd[17391]: conn=110555 op=0 RESULT tag=97 err=0 text=</p> </blockquote> <p>my search:</p> <pre><code>Try Dim search As New DirectorySearcher(enTry) search.Filter = ("(&amp;(objectClass=users)(cn=" &amp; myUser &amp; "))") Dim result As SearchResult = search.FindOne() Dim myResult As Boolean = Nothing If result Is Nothing Then myResult = False Else myResult = True End If .... do some processing here Catch f As Exception Console.WriteLine(f.Message &amp; vbCrLf &amp; f.HelpLink.ToString) End Try </code></pre>
