The next step is configuring the security realm, which defines mapping between user credentials (user name and password) and user roles.

下一步是配置 安全领域，安全领域定义用户凭证（用户名和密码）与用户角色之间的映射。

Note: Since this user mapping is specified without a REMOTE_PASSWORD clause, it does not have the administration pain points associated with password maintenance.

注意：由于指定该用户映射时没有使用REMOTE _ password子句，因为不需要进行痛苦的密码维护管理。

youdao

If the user ID and password you use to connect to the federated database are the same as those you use to access the remote data source, you do not need to create a user mapping.

如果用于连接到联邦数据库的用户ID和密码与用于访问远程数据源的用户ID和密码相同，那么不需要创建用户映射。
