ldap访问AD域的的错误通常会以下格式：java

Ldap load error: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C090334, comment: AcceptSecurityContext error, data 525, vece]安全

其中红字部分的意思以下（这些错误码跟语言无关）：服务器

525 - 用户没有找到架构

52e - 证书不正确dom

530 - not permitted to logon at this timethis

532 - 密码期满url

533 - 账户不可用.net

701 - 帐户期满code

773 - 用户必须重设密码
