Just as a followup. I was not able to get the OWIN version to work. Probably my own fault since I am not familiar enough with OWIN and external auth.
However, I was able to take the MVC version of their library (KentorIT.AuthServices.MVC) and modify their AuthServicesController using some of the ExternalLogin code from your existing AccountController (taken from the AbpMvcSample project). This allowed me to receive the info from our external Identity SAML Provider and add the user to the Abp Users table if it doesn't exist and log the user in.
I haven't been able to fully cleanup the combined code yet, but if anyone else needs SAML support, I would be happy to share.

Because I was using MVC, I started by trying the MVC opion for Kentor. I didn't think about trying the OWIN option (which is a different setup). I will take a look at this info and see if it integrates better and let you know.
Thanks.
