Method Detail

authenticate

public javax.naming.directory.Attributes authenticate(java.lang.String user,
                                                      java.lang.Object credential,
                                                      java.lang.String[] retAttrs)
                                               throws javax.naming.NamingException

This will authenticate by binding to the LDAP with the supplied user and credential. If AuthenticatorConfig.setAuthorizationFilter(java.lang.String) has been called, then it will be used to authorize the user by performing an ldap compare. See Authenticator.authenticate(String, Object, SearchFilter, String[])

Overrides:

authenticate in class Authenticator

Parameters:

user - String username for bind

credential - Object credential for bind

retAttrs - String[] to return

Returns:

Attributes - of authenticated user

Throws:

javax.naming.NamingException - if any of the ldap operations fail

authenticate

public javax.naming.directory.Attributes authenticate(java.lang.String user,
                                                      java.lang.Object credential,
                                                      java.lang.String[] retAttrs,
                                                      AuthenticationResultHandler[] authHandler,
                                                      AuthorizationHandler[] authzHandler)
                                               throws javax.naming.NamingException

This will authenticate by binding to the LDAP with the supplied user and credential. The user's DN will be looked up before performing the bind by calling DnResolver.resolve(String). See AbstractAuthenticator.authenticateAndAuthorize(String, Object, boolean, String[], AuthenticationResultHandler[], AuthorizationHandler[]).

Overrides:

authenticate in class Authenticator

Parameters:

user - String username for bind

credential - Object credential for bind

retAttrs - String[] to return

authHandler - AuthenticationResultHandler[] to post process authentication results

authzHandler - AuthorizationHandler[] to process authorization after authentication

Returns:
