Q's about UserAuthenticators and getName()

[Darren Shepherd]

DefaultUserAuthenticator masks the _name variable in 
ComponentLifecycleBase effectively making it so that no 
UserAuthenticator gets the default name of getClass().getSimpleName().

Then each authenticator, except LDAP, does something like
if (name == null) {
  name = "MD5";
}

So instead of the default MD5UserAuthenticator it comes up with MD5 as 
its name.

So my problem is that LDAP currently has a null name on getName().  So 
which should I do?  Add

if (name == null) {
  name = "LDAP";
}

Or remove the masked variable in DefaultUserAuthenticator such that all 
authenticators names will become the classname.  I just need it to be 
consistent for what I'm doing at the moment.  I'd personally prefer that 
they all just get the default name of getSimpleName().  But I don't know 
if there was some reason it was done this way.
