Preparing python-ldap 2.3

[<mi...@st...>]

HI!

Thanks to David we made good progress getting current HEAD code updated
to reflect changes in OpenLDAP's C SDK.

I'd like to release 2.3 soon since there are some important improvements
in HEAD but not yet released. Therefore testing of HEAD is needed!

Please provide feedback ideally on the mailing list. Thanks.

Ciao, Michael.
