Class MultiSchemeAuthenticationHandler

java.lang.Object

org.apache.solr.servlet.authentication.MultiSchemeAuthenticationHandler

All Implemented Interfaces:

org.apache.hadoop.security.authentication.server.AuthenticationHandler

public class MultiSchemeAuthenticationHandler
extends Object
implements org.apache.hadoop.security.authentication.server.AuthenticationHandler

The MultiSchemeAuthenticationHandler supports configuring multiple authentication mechanisms simultaneously.

The supported configuration properties are:

• multi-scheme-auth-handler.schemes: A comma separated list of HTTP authentication mechanisms supported by this handler. It does not have a default value. e.g. multi-scheme-auth-handler.schemes=Basic,Negotiate
• multi-scheme-auth-handler.schemes.scheme-name.handler: The authentication handler implementation to be used for the specified authentication scheme. It does not have a default value. e.g. multi-scheme-auth-handler.schemes.negotiate.handler=kerberos It expected that for every authentication scheme specified in multi-scheme-auth-handler.schemes property, a handler needs to be configured.
