[NE Router-Troubleshooting] User Login Fails When User Names Carry Domain Names During HWTACAS Authentication

Fault Symptom

The device uses HWTACAS authentication. When a user enters a user name including a domain name, the login fails. The debugging hwtacacs all command output shows the information "status:AUTHEN_STATUS_FAIL."

Fault Analysis

1.     Check the HWTACACS server configurations. The results show that the configurations are correct.

authentication-scheme tacacs
authentication-mode hwtacacs local
authentication-super hwtacacs super
authorization-scheme tacacs
authorization-mode hwtacacs local
authorization-cmd 3 hwtacacs
accounting-scheme tacacs
accounting-mode hwtacacs
domain default_admin
authentication-scheme tacacs
authorization-scheme tacacs
accounting-scheme tacacs
hwtacacs-server tacacs
hwtacacs-server template tacacs
hwtacacs-server authentication
hwtacacs-server authorization
hwtacacs-server accounting
hwtacacs-server source-ip
hwtacacs-server shared-key simple hello

2.     The user name is huawei@default_admin and including the domain name "default_admin." However, the HWTACACS server does not support a user name including a domain name. As a result, the authentication fails. Therefore, you must configure a user name not to include a domain name. After the configuration is complete, the client deletes the domain name from the user name when requesting the HWTACACS server for authentication or authorization.


1.     Run the hwtacacs-server template tacacs command to enter the HWTACACS server template view.

2.     Run the undo hwtacacs-server user-name domain-included command to configure a user name not to include a domain name.

After the preceding operations, users can log in to the device. The fault is rectified.


A user name is usually in the format of "user name@domain name." If the HWTACACS server does not support a user name including a domain name, delete the domain name and then send the user name without the domain name to the HWTACACS server.
