The administrator plans to authenticate the users of a department in the domain huawei. The user name provided for authentication always does not contain a domain name (for example, the user name is zhangsan). In this case, the access device cannot send the user name to the AAA server configured in the domain huawei, and therefore the user fails the authentication. To solve the problem, you can configure the global default domain to huawei.

<HUAWEI> system-view
[HUAWEI] aaa
[HUAWEI-aaa] domain huawei
[HUAWEI-aaa-domain-huawei] quit
[HUAWEI-aaa] quit
[HUAWEI] domain huawei
