We will progressively add repositories to the federated repository and demonstrate the ability to view the different repositories as a logically unified repository for user and group management.

我们将逐渐向联合存储库添加一些存储库，并演示为进行用户和组管理，作为一个逻辑统一的存储库查看不同存储库的能力。

youdao

Using a directory to store user and group information has the advantage of centralizing databases in a single location for reducing user and group management complexity.

使用目录存储用户和组信息的优点是，可以将多个数据库集中于单个位置，以便降低用户和组的管理复杂性。

youdao

A more realistic deployment would use an LDAP registry for authentication and user and group management.

更实用的部署将使用LDAP注册中心进行身份验证、用户和组管理。

youdao

The system provides group management, forums, document repositories, calendar, chat, assignment areas, links, user profile administration on a single and highly integrated package.
