I have an Intranet based ADFS website that uses a standard logon page.
Is it possible to change this in the claims language so that it will automatically accept the user based on the authenticated user currently logged on.
I have looked at using the claim rules language but so far all I have got is
c:[Type != ""] => issue (claim = c);
which I got from a video.
I am assuming that I can add a claim to ADFS which can be tested for the website and grant or deny access.
Any help on the claim, or the claims language would help.
Yes you can.
In the claims-rules wizard, use the middle tab - "Issuance Authorisation Rules".
Refer : Create a Rule to Permit or Deny Users Based on an Incoming Claim.
