BIG-IP APM as a SAML 2.0 Identity Provider for Microsoft Office 365 - SSO Config

Hello Community,

i have successfully Configured BIG-IP APM as a SAML 2.0 Identity Provider for Microsoft Office 365 with the iApp Template .

I can login successfully from internal and external to Office 365. From external and internal I will be redirected to F5 logon Page. Than i have to type in my AD Credentials and i am logged into Office 365.

But my expectation is, when i come from internal that i dont want to type in my Domain Username/Password to authenticate, because i am already authenticated with my active directory.

So what do i need to do in this case to get SSO to my configuration?

Best regards Heiko
