public abstract class AuthenticatorBase
extends ValveBase
implements Authenticator, RegistrationListener
Basic implementation of the Valve interface that enforces the 
<security-constraint>
 elements in the web application deployment descriptor. This functionality is implemented as a Valve so that it can be
 omitted in environments that do not require these features. Individual implementations of each supported
 authentication method can subclass this base class as required.
 USAGE CONSTRAINT: When this class is utilized, the Context to which it is attached (or a parent Container in a hierarchy) must have an associated Realm that can be used for authenticating users and enumerating the roles to which they have been assigned.
USAGE CONSTRAINT: This Valve is only useful when processing HTTP requests. Requests of any other type will simply be passed through.

Field Details- 
smThe string manager for this package.
- 
AUTH_HEADER_NAMEAuthentication header- See Also:
 
- 
REALM_NAMEDefault authentication realm name.- See Also:
 
- 
alwaysUseSessionprotected boolean alwaysUseSessionShould a session always be used once a user is authenticated? This may offer some performance benefits since the session can then be used to cache the authenticated Principal, hence removing the need to authenticate the user via the Realm on every request. This may be of help for combinations such as BASIC authentication used with the JNDIRealm or DataSourceRealms. However there will also be the performance cost of creating and GC'ing the session. By default, a session will not be created.
- 
cacheprotected boolean cacheShould we cache authenticated Principals if the request is part of an HTTP session?
- 
changeSessionIdOnAuthenticationprotected boolean changeSessionIdOnAuthenticationShould the session ID, if any, be changed upon a successful authentication to prevent a session fixation attack?
- 
contextThe Context to which this Valve is attached.
- 
disableProxyCachingprotected boolean disableProxyCachingFlag to determine if we disable proxy caching, or leave the issue up to the webapp developer.
- 
securePagesWithPragmaprotected boolean securePagesWithPragmaFlag to determine if we disable proxy caching with headers incompatible with IE.
- 
secureRandomClassThe Java class name of the secure random number generator class to be used when generating SSO session identifiers. The random number generator class must be self-seeding and have a zero-argument constructor. If not specified, an instance ofSecureRandomwill be generated.
- 
secureRandomAlgorithmThe name of the algorithm to use to create instances ofSecureRandomwhich are used to generate SSO session IDs. If no algorithm is specified, SHA1PRNG is used. If SHA1PRNG is not available, the platform default will be used. To use the platform default (which may be SHA1PRNG), specify the empty string. If an invalid algorithm and/or provider is specified the SecureRandom instances will be created using the defaults. If that fails, the SecureRandom instances will be created using platform defaults.
- 
secureRandomProviderThe name of the provider to use to create instances ofSecureRandomwhich are used to generate session SSO IDs. If no provider is specified the platform default is used. If an invalid algorithm and/or provider is specified the SecureRandom instances will be created using the defaults. If that fails, the SecureRandom instances will be created using platform defaults.
- 
jaspicCallbackHandlerClassThe name of the JASPIC callback handler class. If none is specified the defaultCallbackHandlerImplwill be used.
- 
sendAuthInfoResponseHeadersprotected boolean sendAuthInfoResponseHeadersShould the auth information (remote user and auth type) be returned as response headers for a forwarded/proxied request? When theRemoteIpValveorRemoteIpFiltermark a forwarded request with theGlobals.REQUEST_FORWARDED_ATTRIBUTEthis authenticator can return the values ofHttpServletRequest.getRemoteUser()andHttpServletRequest.getAuthType()as response headersremote-userandauth-typeto a reverse proxy. This is useful, e.g., for access log consistency or other decisions to make.
