详解C#使用AD(Active Directory)验证内网用户名密码

1. 连到内网，找到AD的domain地址

nslookup set types=all_ldap._tcp

2. 验证AD的函数

public bool ADLogin(string userName, string password) { // sample : // LDAP://xxx.com string domain = System.Configuration.ConfigurationManager.AppSettings["AD_Domain"]; try { DirectoryEntry entry = new DirectoryEntry(domain, userName, password); object obj = entry.NativeObject; DirectorySearcher search = new DirectorySearcher(entry); search.Filter = string.Format("(SAMAccountName={0})", userName); search.PropertiesToLoad.Add("cn"); SearchResult result = search.FindOne(); if (result == null) return false; } catch (Exception ex) { log.Error(ex); return false; } return true; }
