F5 APM /w ADFS login page

Hi all,

I'm fairly new to working with APM (and ADFS/SAML in general) so I was wondering if someone could help me figure out what I'd need to accomplish the following:

APM Policy:

Start -> ADFS login page (note 1) -> MFA verification (note 2) -> Assign SSO properties -> Allow

The stumbling block I'm currently at is I don't know how to configure either ADFS, or APM, to present the ADFS authentication portal for APM. Any hints or resources that can be used to accomplish this would be greatly appreciated!

Notes:

1: The ADFS login page, not the APM login page. Our CIO specially wants the ADFS login page to be our only authentication portal.

2: We are using DUO for MFA; I'm guessing there's a way to pull the necessary information on to some sort of landing page in order to accomplish this, like in the example that DUO gives for working with APM
