SP2013 - ADFS Authentification fails

Question

Hi there,
for testing purposes I have set up a sharepoint farm with one sp2013-server, sql 2008R2 and one hostnamed web-application. I have also set up a new certification authority and an adfs-server, both based on windows 2012 r2.
After setting up sharepoint I created a new authentification provider like this:
http://technet.microsoft.com/de-de/library/hh305235%28v=office.15%29.aspx
But after switching my web app to adfs authentification fails with error messages like this:
error id 364:  
Exception details: 
Microsoft.IdentityServer.Web.InvalidRequestException: MSIS7042: The same client browser session has made '6' requests in the last '11' seconds. Contact your administrator for details.
Chrome shows me the ADFS landing page with "an error has occured", but IE just brings up a basic authentification and after entering credentials I see "webpage not found".
What I did:
Rechecked my whole config
Checked the thumbprint of the certificates
$sts = Get-SPSecurityTokenServiceConfig
$sts.LogonTokenCacheExpirationWindow = (New-TimeSpan –minutes 1)
$sts.Update()
Iisreset
Verified the time - is ok
Now I am out of ideas ... can somebody please help me?
Thanks
Marcel

Strange - idpinitiatedsignon.aspx works on chrome and bringt the forms logon - I can log on
Same URL in IE opens the adfs-page, when I click "login" I see a windows security-window for credentials (guess basic authentification)
- after entering I get http 400. 
So I disabled "windows authentification" in my global authentification settings on "intranet" and enabled forms -
then the login works everywhere but I have to enter credentials manually.
Switched back to windows auth - doesn't work on the sharepoint-server but works on the adfs-server itself.
