Add Outlook Web Access Login Options to the APM Logon Page

I am totally stuck trying to get the options for Light Version, Public/Private Access, and the ability to change password at logon, just like ISA serves up as OWA options, using APM. We are using APM, 11.5.2, with iApp template f5.microsoft_exchange_2010_2013_cas_v1.3.0. The Application we created using the template successfully serves out OWA access to our internal CAS servers, however, we are completely unable to pass the options for Light mode, Public/Private, and most importantly, the ability to change password at logon, which is how ISA works when providing delegated authentication as a gateway. The default SSO configuration for authentication appears to be NTLM, even though we are using FBA on all our CAS servers. Is there an official process to put in place that can make happen what we need? I need as much detail as possible in the explanation, as I am new to F5. I've tried all the steps in this post and it appears it gets stuck at the SSO configuration object.... Please help....
