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

Tue Aug 13 19:38:06 UTC 2019

What's the difference between:

"Redistributions in binary form must reproduce ... this list of conditions, and the following disclaimer"

and

"Redistributions must contain a verbatim copy of this document"?

Seems like the same obligation, recited twice using different language.

Also, are there any substantive differences between this license and BSD-3 clause?

----------------

Rationale:

The OpenLDAP Public License has been in use since 1998, with this latest revision in 2003. Previous versions of the license were already OSI approved back in 2001.
https://www.openldap.org/lists/openldap-announce/200206/msg00001.html
I am not aware of the circumstances why the license was de-listed.

It is essentially a BSD 3-clause license. It is currently an FSF-approved license.

----------------

Proliferation category:
Licenses that are redundant with more popular licenses (BSD 3-clause)
