I'm on ADFS 4.0 (Windows Server 2016).
I have an application A which doesn't want to use the ADFS login page.
I have an application B declared as "Relying Party Trust" for the ADFS.
I configure my App A as "Claims Provider Trust".
The App A creates and signs a SAMLResponse
The App A POST the signed SAMLResponse to ADFS /adfs/ls/idpinitiatedsignon
ADFS check the SAMLResponse and redirect the user to the idpinitiatedsignon and says "your are connected".
When I try to go to App B, I have to authenticate my user to ADFS
When I check the cookies, I see SamlSession, MSISIPSelectionPersistent, MSISAuthenticated and MSISLoopDetectionCookie.
Is there a way to get the ADFS MSISAuth Cookie with this flow?
In the logs I have these messages :
- A warning : SSO token is null or empty. Cannot write SSO token to Cookies.
- An error : The supplied Claims Provider Trust property https://myidp.app.A from session cookie is not valid
Thank you in advance for your help.
