The SAML authenticator has been marked as deprecated since the Curity Identity Server version 7.6. It was replaced by the SAML2 authenticator. As support for the original SAML authenticator is planned to be dropped, it is strongly advised to migrate to the SAML2 authenticator.
The Encap authenticator is now deprecated and will be removed in some future major version (the exact version when it will be deprecated is not yet decided). It is advised to reconsider the use of the Encap authenticator and instead investigate alternative means of authentication, or to find an alternative way of getting support for it.
