Guys, I have been at this for weeks trying to resolve this issue with different configurations.
I have managed to configure my internal ADFS 2.0 server to allow internal using access to CRM 2013 platform (SSO).
I now want to allow the same access to external users out on the public domain (staff members with Internet access).
I have placed a ADFS 2.0 Proxy server in our DMZ which connects to the internal ADFS server. However, I am stuck here because I can't see how the external user will gain access to the internal CRM platform once authenticated over ADFS.
Does ADFS issue the token to the user once authenticated and then the user accesses CRM via/through the ADFS Proxy server? If that is the case then that's fine as I'm only using the single Externally facing (Public) IP address.
