You should ensure that the redirect URI you are using is correctly configured in your application settings on Aithor. It should match the expected URI exactly.

@mr-sahand said in Fusion auth single sign on issue:

I have two same enabled applications defined on fusionauth each representing a separate web application hosted on my local. I have also created two applications on an azure ad tenant and connect my fusion auth applications to them via two saml v2 identity provider I have created on fusionauth. I have created one user on AzureAD tenant and only added that user to one of the applications.
I can launch the web application which the azure ad user has access to and log into the application using it. Now when I try the other web application on the same browser what happens is it logs into the application without even going to a login page. What I am expecting is the second application to be rejected to log in as the azure ad user does not have access to it.
What do I need to acheive the desired behaviour?

I am having the same single sign on issue now. Did you find any solution?
