The administrator cannot pass authentication if the administrator's authentication mode is changed to RADIUS authentication on an S series switch

The administrator cannot pass authentication if the administrator's authentication mode is changed to RADIUS authentication. For S series switches (except the S1700), such an authentication failure occurs because the entered user name does not contain a domain name. You need to check whether the user name on the authentication server contains a domain name.
- If the user name on the authentication server contains a domain name, run the radius-server user-name domain-included command in the RADIUS server template view or run the hwtacacs-server user-name domain-included command in the HWTACACS server template view.
- If the user name on the authentication server does not contain a domain name, run the undo radius-server user-name domain-included command in the RADIUS server template view or run the undo hwtacacs-server user-name domain-included command in the HWTACACS server template view.
