Hi
I'm trying to to get the following environment going as a test Lab
- A standalone ADFS server 3.0 Windows 2012 R2
- A standalone SharePoint 2013 server setup to use ADFS
- A sample asp.net app claims aware setup to use the above ADFS.
When I try to access either SharePoint or my sample app, I get redirected to the ADFS login (which is great) but instead of asking for login details it states An error occurred !
Please help!!! I've been stuck for days and need to deliver!
Looking at the ADFS server's event logs I see the following error correlating with every time I try to login:
Encountered error during federation passive request.
