I am new to 365 Federation and am feeling quite dumb today. I have set up a test domain and federated it with Azure. Everything syncs fine between my servers and Azure. However, when attempting to authenticate remotely to Azure or remotely join a computer to the domain I get a cannot connect error. If I go to the MS page and log in with one of my domain users, the login redirects me to my external domain.com/adfs page. I obviously am missing something in my external DNS but cannot seem to find any info on where to point it.
I can't seem to find any info on where to point adfs.mydomain.com.
Please see the attached for my PS output and my current external DNS settings.
