We are setting up and testing adfs version 3.0 on windows 2012 r2.
If I goto the following url's it works
https://adfs.domain.com/adfs/ls/idpinitiatedsignon.htm
https://adfs.domain.com/federationmetadata/2007-06/federationmetadata.xml
https://adfs.domain.com/adfs/services/trust/mex
But if I goto
https://adfs.domain.com/adfs/adfs/services/trust
https://adfs.domain.com/adfs/adfs/ls
https://adfs.domain.com/adfs/adfs/ls/federationserverservice.asmx
