AuthenticationException thrown on invalid LDAP passwd given

I'm getting a pretty annoying reoccurring error in the
server log:

javax.naming.AuthenticationException: [LDAP: error code
49 - Invalid Credentials]

Isnt this a bit harsh to log as an error, just because
a user typed in the wrong password?

JBoss should just silently swallow this - the user is
already being notified of the mistake he/she made.
