我已經在VB中編寫了一個代碼來訪問LDAP服務器以進行身份驗證。但是,它引發異常,可能nativeObject調用正在生成異常。動機是認證用戶。我提供的代碼和例外。請幫我解決這個問題。如何訪問LDAP服務器進行身份驗證
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim cookie As HttpCookie = New HttpCookie("username")
cookie.Value = TextBox1.Text
cookie.Expires = DateAndTime.Now.AddHours(12)
Response.Cookies.Add(cookie)
Dim entry As New DirectoryEntry("LDAP://xyz.com/dc=xyz,dc=com", TextBox1.Text, TextBox2.Text)
Try
Dim obj As New Object
obj = entry.NativeObject
Dim search As New DirectorySearcher(entry)
search.Filter = "(SAMAccountName=" + TextBox1.Text + ")"
search.PropertiesToLoad.Add("cn")
Dim result As SearchResult
result = search.FindOne()
If result.Equals(Nothing) then
MsgBox("Try Again with valid username")
Else
MsgBox("User Found!")
Response.Redirect("~/Dashboard.aspx")
End If
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub
的例外,我已經得到了
System.Runtime.InteropServices.COMException(0x80005000):未知 錯誤(0x80005000)
在System.DirectoryServices.DirectoryEntry.Bind(布爾 throwIfFail)
at System.DirectoryServices.DirectoryEntry.Bind()
在System.DirectoryServices.DirectoryEntry.get_NativeObject()
在_Default.Button1_Click
請爲我提供解決方案/修改代碼REQ。
感謝維納亞克....我解決我的問題。 – snehal
