Great, thanks Emmanuel!

Hm, but as a user of the API I just want to connect, I have to handle
both, the return value and the exception. When I get an Exception I can
see the reason (host not found, invalid credetials, etc). But If I just
get a "false" I don't know any details. I'd prefer to get an exception.

I'd say it's optional to refine them.

CodecService sounds ok to me.

But, I wonder if this service needs to be exposed via the LdapConnection
interface at all? Does a user of the LDAP API ever need it? I guess only
if she want to register new controls or extended operations
programatically, but that can also be done by setting system properties
