> Logic and declaration used to determine if SSO is enabled for a service needs
> to be able to handle more than a boolean property.
> The current way Ambari determines whether SSO is enabled for a service or not
> is by getting the value of the property indicated in
> {{sso/enabledConfiguration}} property in the service's metadata:
> {code:java|title=Example}
> <sso>
> <supported>true</supported>
>
> <enabledConfiguration>service-properties/sso.knox.enabled</enabledConfiguration>
> </sso>
> {code}
> Using the above example, the {{service-properties/sso.knox.enabled}} is
> checked to see if its value is "true" or "false".
> This method works for a few services, but other services require more
> elaborate checks. For example Oozie relies on the value of
> {{oozie-site/oozie.authentication.type}}. If the value is
> "org.apache.hadoop.security.authentication.server.JWTRedirectAuthenticationHandler",
> then SSO is enabled; otherwise it is not. This is different that just a
> Boolean value.
> *Solution*
> To support a more robust method to determine whether SSO is enabled or not, a
> new attribute should be added - {{ssoEnabledTest}}. The existing attribute,
> {{enabledConfiguration}}, should be available for backward compatibility -
> but converted on the backend.
> The {{ssoEnabledTest}} attribute is to contain a JSON document that can be
> _compiled_ into a {{org.apache.commons.collections.Predicate}} (ideally using
> {{org.apache.ambari.server.collections.PredicateUtils#fromJSON}}). For example
> {code:java}
> <sso>
> <supported>true</supported>
> <ssoEnabledTest>
> {
> "equals": [
> "service-properties/sso.knox.enabled",
> "true"
> ]
> }
> </sso>
> {code}
> {code:java}
> <sso>
> <supported>true</supported>
> <ssoEnabledTest>
> {
> "equals": [
> "oozie-site/oozie.authentication.type",
>
> "org.apache.hadoop.security.authentication.server.JWTRedirectAuthenticationHandler"
> ]
> }
> </ssoEnabledTest>
> </sso>{code}
