    this test server is from http://blog.stuartlewis.com/2008/07/07/test-ldap-service/comment-page-1/#comment-3588

    The error returned below is 'invaid dn syntax has been specified'. 

    Dim dirEntry As New DirectoryEntry("LDAP://ldap.testathon.net/OU=users,DC=testathon,DC=net")  'ive tried various url variations
            'Setting username & password to Nothing forces
            'the connection to use your logon credentials
            dirEntry.Username = "stuart"
            dirEntry.Password = "stuart"
            'Always use a secure connection
            dirEntry.AuthenticationType = AuthenticationTypes.None  'ive tried various settings such as Secure,Anonymous, etc. nothing works
            Return dirEntry


    any help would be greatly appreciated!  i'm on my second advil for the day!

    what i would like to do is to verify that i can code a query against an ldap server. i have this example code and a couple of others but can never verify against any test servers.  i have a vb.net application which the customer is requesting a login to their active directory, but i can even demonstarate a connection to a ldap server.  any ideas? thanks again for your help.

    See this code http://www.codeproject.com/KB/system/active_directory_in_vbnet.aspx

    I tried a couple of the sample code functions (IsValidADLogin) and it worked on my domain so the code does work.

    I'll check out this code, but how can I test it?  I don't have AD on my xp pro computer and I don't know of a test server other than the url I sent in my earlier post.   

    My main goal is to just create a piece of code that works against the test server (http://blog.stuartlewis.com/2008/07/07/test-ldap-service/). 

    thank you.
