Logging into the Web Isolation Cloud management console using a SAML provider results in the error 'Login denied by identity provider. Check settings.'
SAML assertion encryption is enabled in the Identity Provider's configuration with an algorithm that is not supported by Web Isolation Cloud.
Web Isolation Cloud supports the following SAML assertion encryption algorithms:
AES256-CBC
AES128-CBC
TRIPLEDES-CBC
Select one of these algorithms in the Identity Provider's settings and perform a full login (this may require clearing browser cookies for your IdP login URL).
