[License-review] For Legacy Approval: OpenLDAP Public License

Hi Henrik,

An upgrade clause allows a licensor who is the license steward to
arbitrarily change terms in the license - for example changing a BSDish
license to a GPLish one. All licensees would automatically have "accepted"
the applicability of the new terms.

Thanks,
Van
