写了一个通用的认证类，请看代码

string strLDAPAdminPwd = txtLPwd.Text; 
string strMsg = ""; 
bool blRet = objldap.OpenConnection(strLDAPPath, strLDAPAdminName, strLDAPAdminPwd); 


if (blRet) 
{ 
blRet = objldap.CheckUidAndPwd(strLDAPFilter, TestUserID, TestUserPwd, ref strMsg); 
if (blRet) 
{ 
strMsg = "检测用户名" + TestUserID + "和密码" + TestUserPwd + "成功"; 
} 
else if (!blRet && string.IsNullOrEmpty(strMsg)) 
{ 
strMsg = "检测用户名" + TestUserID + "和密码" + TestUserPwd + "失败"; 
} 
} 
this.txtLog.Text = System.DateTime.Now.ToString() + ":" + strMsg + "\r\n" + "\r\n" + this.txtLog.Text; 
MessageBox.Show(strMsg); 
} 
}

LDAP是轻量目录访问协议，英文全称是Lightweight Directory Access Protocol，一般都简称为LDAP。它是基于X.500标准的，但是简单多了并且可以根据需要定制。与X.500不同，LDAP支持TCP/IP，这对访问Internet是必须的。LDAP的核心规范在RFC中都有定义，所有与LDAP相关的RFC都可以在LDAPman RFC网页中找到。
