In some network configurations involving a reverse proxy, the base url generated by the underlying SAML library is not consistent with the way it's generated in NextCloud.
For example, it may generate
http://
urls instead ofhttps://
when the SSL Layer is handled by a proxy, even when NextCloud URLGenerator#getAbsoluteURL effectively generateshttps://
urls.This change setup SAML library to use the Server Protocol and Server Host as returned by the NextCloud Request object to build SAML urls properly.
