I scrolled down to the SAML v2 Integration details. I then copied the link for the Metadata URL. I pasted that in a browser window and got the xml.
I then copied the xml into the Upload Data text box on IAMShowcase. When I submitted that I received a url that allowed me to see the following.
Paste that url on the browser and still receive the error message from fusionauth -
"The login URL does not contain the tenant Id. Ensure your URL includes the tenantId in the format: /samlv2/login/{tenantId}."
After that, I went to WebAuthN Wizard and completed the steps and still receive the error message from fusionauth.
I looked at the SP XML configuration and saw that the destination for the login did not include the tenantId, therefore, I keep on getting the error message. Am I doing something wrong? But if I were to use the "Initiate login URL" that is in my : Application -> View -> SAMLv2 Integration section and use the login credentials, I am able to successfully access the IAMShowcase federated page.
