Guidance setting up a DMZ proxy for Citrix ShareFile

I am looking into setting up our F5 as the DMZ proxy for Citrix ShareFile. I have seen some discussions about some setting it up as an SAML IdP, (with issues with SLO). Is an IdP necessary as part of the proxy for ShareFile? Does anyone else have experience using F5 APM with ShareFile or can point to some F5 documentation for this? Thanks in advance for your help,
