Temporary MFA bypass in CAS 5.1

[Adam Causey]

Is there a way to programmatically temporarily disable MFA in CAS 5.1?

We need to write a custom module that decides if the user should see the MFA prompt.  We have tried adding a Groovy script to set a user attribute of 'bypass=true' and then filtering, however since the user attributes are cached we are running into roadblocks.

Is there a way to clear the attributes cache and/or some other way to temporarily bypass the MFA webflow?

Thanks,

Adam
