Single Sign On(SSO) using SAML token

Cache 2017.1 supports Kerberos and OpenAM, which are both SSO methods.  You can also implement your own authentication methods using delegated authentication, or use LDAP to do logins with domain accounts (which is not full SSO since you have to type the login again, but sometimes people call it that because it's just one account.)   If you want to set up SSO via SAML, you'll need to write some code to handle that, there isn't anything that can be enabled by just configuring it.
