It appears that the latest update of WP SAML Auth (2.2.0) causes an "Invalid provider specified for SAML authentication" error message when I try to sign in using SSO. My site uses SimpleSAMLphp v2.3.7, which is added via Composer, and was working fine with WP SAML Auth v2.1.4. Logging in manually via a username/password works fine, it's just the SSO login that fails. Any thoughts or suggestions would be greatly appreciated!
