Problem with ReturnURL Dynamics NAV 2016 with Azure AD and Office 365 login

BT_Marc

Hi all,

i am trying to configure Dynamics NAV 2016 to work with an Azure AD and the Office 365 Login. What I achieved so far is that the login works. NAV knows the users of the Azure AD and I can sign in. If we use the web client with by “httsp://NAMEOFSERVER/DynamicsNAV90/WebClient/
it directs to the Office 365 Login page. Now we sign in and get back to

"https://NAMEOFSERVER/DynamicsNAV90/WebClient/SignIn.aspx?ReturnUrl=/DynamicsNAV90/WebClient/"

Now of course we get an error message that the site can’t be displayed. If we remove manually the “SignIn.aspx?ReturnUrl=%2fDynamicsNAV90%2fWebClient%2f” it shows the WebClient and dynamics NAV works well.
My question is where dose the “SignIn.aspx?ReturnUrl=%2fDynamicsNAV90%2fWebClient%2f” come from and how do I stop IIS, NAV or Azure from adding it?

Thanks in advance.
Marc
