  LDAP works on Development Server but not on Windows Server 2008

  Aug 21, 2013 03:30 AM|razorfire|LINK

  Hi,

  I'm working on a solutions that require to get the windows authentication identity via Asp.net. It works perfectly on the development server as it retrieved my windows identity

  However, things turns around when it comes to the server side. I can't seemed to find the problem.

  These are my settings,

  Server IIS 7.0

  Windows Authentication enabled

  Application Pool= Network Service

  Loaduserprofile is set to true.

  On the code side would be

  System.Threading.Thread.GetDomain.SetPrincipalPolicy(System.Security.Principal.PrincipalPolicy.WindowsPrincipal)
          Dim pl As New WindowsPrincipal(System.Threading.Thread.CurrentPrincipal.Identity)
  
          Dim pr As New PrincipalContext(ContextType.Domain)
          Dim up As UserPrincipal = UserPrincipal.FindByIdentity(pr, pl.Identity.Name)
          Dim cn As String = "The LDAP connection works"
  
  
  
          Dim dssearch As New System.DirectoryServices.DirectorySearcher
          Dim sresult As System.DirectoryServices.SearchResult
          Dim dresult As System.DirectoryServices.DirectoryEntry
  
          dssearch = New System.DirectoryServices.DirectorySearcher(cn)
          dssearch.Filter = "(userPrincipalName=" & up.UserPrincipalName & ")"
          sresult = dssearch.FindOne()
          dresult = sresult.GetDirectoryEntry()
  
          txt_givenname.Text = up.GivenName
          txt_lastname.Text = up.Surname
          txt_loginname.Text = pl.Identity.Name
          txt_email.Text = up.EmailAddress
          txt_department.Text = dresult.Properties("department").Value.ToString()

  
  

  Configuration check results:

  Configurations check is

  .NET version is: 2.0.50727.5466

  Identity is:

  Authentication is: False

  Application Pool Identity is: NT AUTHORITY\NETWORK SERVICE

  Identity Authentication Type is: Negotiate

  
  

  
  

  Error would be:

  The (&(objectCategory=user)(objectClass=user)(|(userPrincipalName=)(distinguishedName=)(name=))) search filter is invalid.

  Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

  From my side, it's seems that profile didn't load, but i'm plucking out my hair because of that issue.

  Can some please enlighten me?

  Thank you!

  When i replace pl.Identity.Name using my hardcoded Identity name, it works and the application runs.

  So the issue is in i'm not getting the identity.Name

  Things to check

  1) what is set in the web.config, windows authentication?

  <authentication mode="Windows" />
  <authorization>
     <deny users="?"/>
  </authorization>
  <identity impersonate="false" />

  2) Is anonymous access in IIS disabled?
  3) Try HttpConext.Current.User instead of Thread.CurrentPrincipal

  dssearch.Filter = "(userPrincipalName=" & User.Identity.Name.Split("\".ToCharArray())(1) & ")"

  Hi smirov,

  It now works. 

  I'm missing 

  <identity impersonate="false" />

  I thought impersonate is false by default? Cause, i remember my IIS ASP.NET Impersonation is disabled.

  Thanks!
