LDAP服务器不可用。 C＃ASP.net

Question

我是LDAP编码的新手。我开发了以下简单代码来测试我的LDAP服务器，但是我收到错误：“LDAP服务器不可用”。但我从LDAP服务器获取cmd中的ping回复。任何人都可以帮忙吗？

   string domain= "ldaps://SomeDomainName.com:636";  

        PrincipalContext AD = new PrincipalContext(ContextType.Domain,domain);
        UserPrincipal u = new UserPrincipal(AD);
        PrincipalSearcher search = new PrincipalSearcher(u);
        foreach (UserPrincipal result in search.FindAll())
        {
            if (result != null && result.DisplayName != null)
            {
                DropDownList1.Items.Add(result.DisplayName);
            }
        }

Answer 1

您必须提供名称。从域字符串中删除ldap。例如，

string domain= "SomeDomainName.com:636";  

        PrincipalContext AD = new PrincipalContext(ContextType.Domain,domain);
        UserPrincipal u = new UserPrincipal(AD);
        PrincipalSearcher search = new PrincipalSearcher(u);
        foreach (UserPrincipal result in search.FindAll())
        {
            if (result != null && result.DisplayName != null)
            {
                DropDownList1.Items.Add(result.DisplayName);
            }
        }
