Nextcloud SAML SSO Authentication through Microsoft Azure Active Directory

Hello,

I have configured at Microsoft Azure to automatically login to Nextcloud with SsO. The advantage is a user in MS azure can also login to Nextcloud and can save documents.

I have used that documentation for configuration:

https://medium.com/@ntrussell/enable-nextcloud-sso-authentication-through-microsoft-azure-active-directory-saml-abe37d735cd

Now at Windows clients the SSO (Single Sign On) login to Nextcloud works well.

But at IOS Devices for example Ipads Version 14. not work. I get a failure message when enter the URL of the nextcloud instance: Certificat is not valid. Connection will refused.

The nextcloud version is very actual and is hosted at a host Provider.

Can somebody help me Preise?
