Vision portal SSO login

[JKalmari]

We have a working Azure SSO login to Meraki dashboard (made following the Meraki documentation) but for some reason SSO doesn't work on Vision Portal. 

After giving credentials and passing MFA I get this error:

"The server encountered an SSO error. Please contact your network administrator for assistance. For reference, your login was at Nov 25 09:54:34 UTC from xx.xxx.xxx.xxx."

I tried making another app to the Azure just for Vision SSO login, but it didn't work either. 

Any ideas welcome.

Does dashboard show anything in the SAML history log for these failed login events? And if yes, what is the error?
