 ## Limitations of LDAP authentication
 
 * The current LDAP feature of Doris only supports plaintext password authentication, that is, when a user logs in, the password is transmitted in plaintext between client and fe and between fe and LDAP service.
-* The current LDAP authentication only supports password authentication under mysql protocol. If you use the Http interface, you cannot use LDAP users for authentication.
-* Temporary users do not have user properties.

 ## LDAP验证的局限
 
 - 目前Doris的LDAP功能只支持明文密码验证，即用户登录时，密码在client与fe之间、fe与LDAP服务之间以明文的形式传输。
-- 当前的LDAP验证只支持在mysql协议下进行密码验证，如果使用Http接口则无法使用LDAP用户进行验证。
-- 临时用户不具有用户属性。
