SSL VPN Kerberos delegation in sharepoint environment With multiple embedded internal resources.

I am new to F5 and I have recently downloaded a trial appliance. I come to you guys to see if APM will work in our environment before I dive in and start configuring. We have an internal sharepoint site that we would like to be able to access outside of our network. The ideal situation is to have a SSL VPN to the site that delegates kerberos tickets to all internal servers that need authentication. Our topography is a sharepoint site that has internal server resources embedded via webparts or page viewers that all require kerberos authentication. Is it possible for APM to identify and delegate kerberos tickets to any servers that request a kerberos ticket? I read in the documentation that kerberos delegation only works for IIS servers, is this true?
