Displaying a simple error page from a flow

[Wessel, Keith]

I tried to figure this one out for myself, but when I was convinced I was taking the wrong route, well... here I am back on the list.

On the same project as I was working on earlier this week with a customized MFA flow, I want to display a message to users if they haven't enrolled for a Duo token but the SP they're signing into requires Duo. I was going to create a flow for this purpose, but after reading the V3 authentication docs, it seems like a lot of work to create a custom authn flow that simply displays a velocity template with a static message. Is there any way to throw an exception from within a script in the MFA configuration that I could map to a specific error message within error.vm and related messages?

Or is there some other easy way to have a custom message or velocity template displayed that I'm not thinking of?

I can move ahead with my flow creation, but I'm convinced I'm making the job ten times harder than it needs to be.

Thanks very much,
Keith
