@mike-rudat Thanks for the reply, Mike. I've read up on the SAML V2 Reconcile Lambda. It seems that you can only apply that to an IdP in Home -> Settings -> Identity Providers. I'm not using and IdP setup from Home -> Settings -> Identity Providers (should I be?).

So when I go to my application Home -> Applications, I see that I can set a Populate Lambda, but not a Reconcile Lambda.

So how do I assign a Reconcile Lambda to my application? Or, is that not the right way to do it?

that last line was supposed to be...

registration.data.mobilePhone = '777-123-4567';

I have FA configured as a SAML v2 IdP. I'm trying to update the user and/or registration objects via the populate lambda. Just doing something like this doesn't seem to have any affect...

function populate(samlResponse, user, registration) {
  user.mobilePhone = '444-123-4567';
  user.data.mobilePhone = '555-123-4567';
  registration.mobilePhone = '666-123-4567';
  registration.mobilePhone = '777-123-4567';
}

Is there a 'save' step that I'm missing or some other mechanism to get those changes to 'stick'?

@mark-robustelli Thanks, Mark. After having worked with FA some more, I now realize that I don't need it to be a GET. Thanks for the response.

When setting up SAML for an application, I understand it will redirect to the first entry in the ‘Authorized redirect URLs’ config setting. When it does that redirect, it seems to do it as a POST. Is there a way to change that to a GET?
