是否可以使用System.DirectoryServices.Protocols中的LdapConnection来查询Active Directory?
我在实例化PrincipalContext时遇到问题。这是我的代码,以防万一有人发现该问题:
private LdapConnection getLdapConnection(string username, string password, string ldapServer, bool secured)
{
int port = secured ? 636 : 389;
LdapConnection connection = new LdapConnection(new LdapDirectoryIdentifier(ldapServer, port, false, false));
if (secured)
{
connection.SessionOptions.ProtocolVersion = 3;
connection.SessionOptions.SecureSocketLayer = true;
}
connection.Credential = new NetworkCredential(username, password);
connection.AuthType = AuthType.Basic;
connection.SessionOptions.VerifyServerCertificate += (conn, cert) => { return true; };
connection.Bind();
return connection;
}
尝试实例化我正在使用的主体上下文时
PrincipalContext context = new PrincipalContext(
ContextType.Domain,
ldapServer,
null,
useSsl ? ContextOptions.SecureSocketLayer | ContextOptions.SimpleBind : ContextOptions.SimpleBind,
username,
password);
为了完整性,我传入相同的值,用户名采用
domain\user
格式,ldapServer则采用server.domain.com
格式,并且在创建Principal Context时,ldapServer附加了:636。我连接到的服务器存在证书问题,我认为这可能会阻止此问题,因为LdapConnection设置为返回true进行验证。这不是问题,因为值得信任。我无权访问服务器,因此无法更改此设置。
最佳答案
据我了解,定位域时,容器参数不能为null
。您可以尝试以下构造函数:
PrincipalContext domainContextMonou = new PrincipalContext(ContextType.Domain,
"server.domain.com :389",
"dc=domain,dc=com",
username,
password);
然后这个:
PrincipalContext domainContextMonou = new PrincipalContext(ContextType.Domain,
"server.domain.com :636",
"dc=domain,dc=com",
useSsl ? ContextOptions.SecureSocketLayer | ContextOptions.SimpleBind : ContextOptions.SimpleBind,
username,
password);
