EAC Restrict Access does not work for Exchange 2016 via iApp

Added a new irule, I was hoping to display this page after the user is authenticated via the apm. Any thought's?

Thanks in advance. Josh

Hi Guys,

Any comments on the EAC function of the iapp? as per the below 2 points. Are we looking at updating the deployment guide and iapp at some point or are we missing something?

"Anyway, there seems to be 2 things here: 1) The APM acl function does not work (not matching a certain string); and 2) it seems pointless to have this function from your perspective."
