Shibboleth authentication

I have nextcloud vers 15.02 installed, I’m trying to configure it for shibboleth authentication only.
I downloaded the SSO & SAML authentication app and enable it. I setup all the required paramaters within the same for acessing our iDP provider. I also modified the nextcloud virtual host configuration in order to enable shibboleth at the apache level. I restarted our shibd daemon, restarted apache but the nextcloud login page is the same , it seems that shibboleth is not enabled in nextcloud , what I’m missing?

Thanks
Marcello
