FYI,

conftest.c:150:2: error: #error "BerkeleyDB 6.0.20+ license is incompatible with LDAP"
 #error "BerkeleyDB 6.0.20+ license is incompatible with LDAP"

configure: error: BerkeleyDB version incompatible with BDB/HDB backends

Fixed at r14475.

Leaving open for proper rephrasing of license problem.

I think the license issue is not valid. From ​http://www.oracle.com/technetwork/database/berkeleydb/downloads/licensing-098979.html is says:

"Oracle employs a dual licensing model that offers customers a choice of either our open source license or a commercial license. Our open source license is OSI-certified and permits use of Berkeley DB in open source projects or in applications that are not distributed to third parties. Our commercial license permits closed-source distribution of an application to third parties and provides business assurance."

If it's ok for open source projects, then it's ok for openldap.

I will remove the warning and then close this ticket after commit unless I hear a different opinion first.

Fixed now at rev 14477.

Thinking about it, if there is a problem with the bdb package, the warning should have been there, not with openldap.

The problem is not in license itself, but in an incompatibility between different OSS licenses. Current AGPLv3 license is incompatible with anything that isn't GPLv3+ as far as I am aware of, and OpenLDAP license looks like kind of BSD license to me.

I believe you can't link to a GPLv3 code (AGPLv3 being GPLv3 like license) unless your code is GPLv3 too, given that GPLv3 is incompatible with GPLv2. That's why FSF came up with LGPL, a license mainly used by libraries that give an opportunity to link LGPL code even into proprietary products, while enjoying other benefits of GPL(-like) licenses.

Again, I'm not into software licensing, and this is all new to me, but I've made some assumptions in this reply from information that I gathered around web.
