Can you confirm which of these steps you completed please?

1. Enabled Claims based authentication in the CRM deployment manager
2. in adfs, add the relying party trust for both internal and external authentication
3. for both relying party trust, added the claims rules (I think there are two) specified in the documentation.
4. Configured IFD in the CRM deployment manager.

The only thing left to do was to configure IFD in CRM , I understood the documentation in such a way that you should be able to login after the internal trust was established.
I will finish the installation and see where that leads me

Correct. You can just configure claims based authentication for internal access only without configuring IFD.

I found my solution in some KB article, I had to allow the webs Loopback access from local host, After that was done , Claims based Auth was working. I have setup the ifd part as well, and have gotten everything to work. The registry key is set as shown blow for future reference.
1: Open up the registry editor by typing regedit under Run.
2: Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0
3: Right-click MSV1_0 and click New and choose to make it a Multi-String Value.
4: Enter BackConnectionHostNames as name for the entry, and double-click it to modify it.
5: Type the hostnames you need to use ( for instance).
6: Restart IISAdmin Service (“Start” -> “Administrative Tools” -> “Services”)

Glad you found the answer, thanks for posting the registry entry. Do you have a reference to the KB article?

Did some research and found the solution
Thanks for that, that was the solution.

I am running now in 2 more problems:

1. The first time, the site opens, the dashboard shows an 404 error. I have to click on Dashboard and the dashboard loads. CRM 2011 RU2 is already installed.
2. The performance with IFD is slow, The average load time is 3 seconds and internal I have an average page load time of 0.7 - 1 second.

Do you have any ideas?
