Error messages used to be of the flavor (this is copied from a 2.2 ITS):
Result: Internal (implementation specific) error (80)
Additional info: password hash failed

Now they look like:
ldap_bind: Server is unwilling to perform

"Additional info" is very useful. For instance, the above could be
ldap_bind: Server is unwilling to perform (53)
Additional info: unauthenticated bind (DN with no password) disallowed

Unless there was a good reason why this was taken out, I can't see how the
shortened error messages obey the principle of least surprise.
