[~HUAWEI-hwtacacs-tac] undo hwtacas-server user-name domain-included

In V800R008C00 and later versions, an HWTACACS template having the undo hwtacacs-server user-name domain-included configuration cannot be bound to the default admin domain or a domain having the adminuser-priority level configuration (configuration restoration is not affected).
solution :
Run the hwtacacs-server user-name original command to override the undo hwtacacs-server user-name domain-included configuration.
and remember commit configuration .
