Yes, You can see the same on trap logs. But due to the line limitation on the Traps to show on WLC. Post certain messages old one will not be available on the WLC. Its better to configure a external syslog server to forward those logs.
But why you want to see on WLC, TACACS is not configured on WLC?

As far as I know successful logs you can't see on Prime.
