how to add duo principals in mfa script

[Jim Fox]

I'm implementing a cookie-based 'remember-me' feature, so users can avoid the 2nd factor dialog when they use a previously used browser.

To do that I'd like my MFA script to be able to force all the Duo supported principals into the MFA's results. ( as if I had run the duo flow )

How can I do that in the mfa script?

Thanks,

Jim
