F5 APM Office 365 Access

Hi guys:

I am deploying an F5 box with APM 14.1.0 and I am having issues to allow users to connect to Office 365 suite. I created a Webtop and a Portal Access with the https://www.office.com/?auth=2 as the URI and the www.office.com as the server with paths like /*. I have not succeeded with such configuration. I have an AD server that allows me to authenticate users and no more. The users need to enter the APM VS and click in the button of Office 365 and then go outside to the Office 365 platform. I know that Portal Access is a feature used to access an internal service, but I need to give the users access to Office 365 in the Internet. I have just found information about F5 APM IdP and SAML, but I think it is not what I am looking for as I just need to allow users to access Office 365 across the F5 APM. I found this article, but it is not quite clear https://www.theinsecurewire.com/configuring-f5-big-ip-apm-webtop-with-office-365/. Do you know a simple method to achieve this requirement?

Thanks

Luis
