I am attempting to establish authentication using Azure AD for a SharePoint 2013 site.
I followed the instructions in the article here.
Everything appears to work correctly as I am presented with a drop down that contains the Azure AD instance as an option and selecting this option redirects to the Azure AD sign in page. What does not work correctly is after authenticating the login page (with the drop down list) is presented again. This process repeats. It seems as though Azure AD is aware that it has already issued a token as each subsequent trip to Azure AD does not prompt for authentication.
Hopefully, this is caused by something minor I have missed. Any suggestions with regards to things to try will be most appreciated.
