public class DynamicAuthenticationFilter
extends org.apache.shiro.web.filter.authc.FormAuthenticationFilter

When combined with the NegotiateAuthenticationStrategy, this filter can be used to allow a client to choose which authentication filter is used at runtime. This filter assumes the shiro.ini is configured with both the NegotiateAuthenticationRealm and some User/Password Realm like: GroupMappingWaffleRealm. Requires use of NegotiateAuthenticationStrategy when more than one realm is configured in shiro.ini (which should be the case for multiple authentication type options). To use NegotiateAuthenticationRealm, the client must pass the parameter PARAM_NAME_AUTHTYPE with a value of PARAM_VAL_AUTHTYPE_NEGOTIATE. Example shiro.ini snippet below:

  # =======================
  # Shiro INI configuration
  # =======================
 
  [main]
 
  # Setup custom AuthenticationRealm
  waffleRealmSSO = waffle.shiro.negotiate.NegotiateAuthenticationRealm
  waffleUserPass = waffle.shiro.GroupMappingWaffleRealm
  securityManager.realms = $waffleRealmSSO, $waffleUserPass
 
 
  # Use the configured native session manager:
  sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager
  securityManager.sessionManager = $sessionManager
 
  # the following call is only necessary in a web-configured ShiroFilter (otherwise
  # a native session manager is already enabled):
  securityManager.sessionMode = native
 
 
  # cookie for single sign on
  cookie = org.apache.shiro.web.servlet.SimpleCookie
  cookie.name = SSOcookie
  cookie.path = /
  securityManager.sessionManager.sessionIdCookie = $cookie
 
 
  authcStrategy = waffle.shiro.negotiate.NegotiateAuthenticationStrategy
  securityManager.authenticator.authenticationStrategy = $authcStrategy
 
  # Waffle filter
  waffleFilter = waffle.shiro.dynamic.DynamicAuthenticationFilter
 
  #Configure filter chains and filter parameters
  authc.loginUrl = /login.jsp
  waffleFilter.loginUrl = /login.jsp
  logout.redirectUrl = login.jsp
 
  ...
 
  [urls]
  # The 'urls' section is used for url-based security
  /logout = logout
  /* = waffleFilter
