NextCloud SSO SAML

Hi the Teams,

I have the latest version of NextCloud (CentOS 7.9) and I search a good tuto to put SSO Oauth2 or SAML windows Microsoft Aazure. I try with this link Enable Nextcloud SAML SSO Authentication through Microsoft Azure Active Directory | by Nate Russell | Medium but i think the version of NextCloud its not the same. I have a strange error when i tried to configure it. : AADSTS700016.
Thanks for your help !
Best regards
