# Class AuthenticationException

java.lang.Throwable
java.lang.Exception
javax.naming.NamingException
javax.naming.NamingSecurityException
javax.naming.AuthenticationException

All Implemented Interfaces:
  `Serializable`

public class AuthenticationException extends NamingSecurityException
This exception is thrown when an authentication error occurs while accessing the naming or directory service. An authentication error can happen, for example, when the credentials supplied by the user program are invalid or otherwise fail to authenticate the user to the naming/directory service.

If the program wants to handle this exception in particular, it should catch AuthenticationException explicitly before attempting to catch NamingException. After catching AuthenticationException, the program could reattempt the authentication by updating the resolved context's environment properties with the appropriate credentials.

Synchronization and serialization issues that apply to NamingException apply directly here.

  1.3
