Your guess is as good as ours. The people who put this licence in are no 
longer involved with the project, and the full authorship history was 
not preserved.

This was discussed in the past:
- https://mail.python.org/pipermail/python-ldap/2012q2/003119.html
- https://mail.python.org/pipermail/python-ldap/2014q2/003374.html
- https://github.com/python-ldap/python-ldap/issues/233

I assume that the license is the sentence that refers to "Python-style 
license" and assume this means a highly permissive open source license 
that only requires preservation of the text of the LICENCE file 
(including the disclaimer paragraph).
(This is based on recent legal advice, but I am not a lawyer and advice 
meant for me might not apply to you.)

I just opened a PR that:
- adds this clarification to the README
- puts future contributions under MIT

And that's the best we can currently do.
