我无法使用LDAP成功验证ASP.NET Web应用程序的用户 . 我已经在我们自己的网络上针对Active Directory这样做了，但这是针对我们网络之外的服务器，即OID(Oracle Internet Directory) .

通常，我使用以下代码没有问题 .

Dim myDirectoryEntry As New System.DirectoryServices.DirectoryEntry("LDAP://1.2.3.4:999/OU=SomeOU,DC=Something,DC=com")

myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Sealing

myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Secure

Try

myDirectoryEntry.Username = txtUserID.Text.Trim

myDirectoryEntry.Password = txtPassword.Text.Trim

Dim mySearcher As New System.DirectoryServices.DirectorySearcher(myDirectoryEntry)

mySearcher.Filter = ("(anr= " & txtUserID.Text & ")")

Dim result As System.DirectoryServices.SearchResult = mySearcher.FindOne

Catch ex As Exception

'failed log in handling

End Try

对于这个应用程序，我将反对我们网络外的目录，上述方法失败(服务器不支持请求的身份验证方法 . ) .

我可以使用以下命令成功绑定到LDAP服务器：

Dim serverName As String = "1.2.3.4:999"

Dim dn As String = "cn=somename,cn=users,dc=something,dc=gov"

Dim ServerCon As New LdapConnection(serverName)

ServerCon.AuthType = AuthType.Basic

Dim cred As New System.Net.NetworkCredential(dn, "password")

ServerCon.Bind(cred)

之后，我找不到用密码验证用户登录信息的方法，然后撤回一些信息 .
