Are you looking to have APM act as SAML SP and be able to use ACS Service Index? Can you please describe your desired use case and why your IDP is using this? APM does not support this today for SP side(it can though use multiple ACS indexes when acting as IDP). Please open support case with F5 and ask for your request to be linked to bug id 572455 which tracks this as an RFE

Thanks Michael. That this is not supported pretty much answers my question. The use case is that we are using an external IdP that not only supports the use of ACS indexes, but prefers their use over directly adding the ACS URL to AuthnRequest. They have just sent me an email asking that I use them. I'll take a look at the bug id you just mentioned.
