Hi Simon,

the difference between remote and embedded server is natural : when
using a remote server, all the messages are encoded into an ASN.1 BER
encoded byte array, and decoded on the server, but we use our home
made BasicAttributes, which is case insesitive.

Hi Alex

Your suggestion makes good sense, a developer would get early visibility of
any attempt to use the "wrong type" of BasicAttributes.

However, I now have code that used to work with DS 1.0.0 that no longer
works with DS 1.0.2, furthermore I have code that will work if used with a
remote context (i.e. via LDAP communications) and won't if I run with an
embedded directory context.

It's the inconsistent behaviour of the same interface between versions and
remote/local contexts that I have found confusing.

Is there any way we can have the old behaviour back where it didn't see to
matter what type of BasicAttributes() we used?  :o)

Kind Regards

+1 on all of Emmanuel's points.  Let me add one additional option.

We could write some protective code to detect when the BasicAttributes is
created without the
boolean argument for ignoring case.  We should have some kind of
RuntimeException for it.
Could be a ConfigurationException maybe?  Don't know exactly but basically
we need:

BasicAttributes attrs = ...
if ( ! attrs.isCaseIgnored() )
{
     throw new "something that tells the user to correct this miss
configuration of BasicAttributes";
}

WDYT?

Alex
