Quoting masarati@aero.polimi.it:
Perhaps someone at Debian could. You need to explicitly request "make test" to run the test suite using OpenLDAP's make. That's all that ships with OpenLDAP. The rest isn't ours.
I think I found the cause. It's the last three lines in Makefile.in (Apr 13 2010):
check: test
test: FORCE
cd tests; make test
I suspect that if I remove them, the tests may be disabled.
This file also contains an OpenLDAP Foundation copyright notice, so I
guess the Debian maintainers added those lines. On the other hand,
these lines also appear in the copy of Makefile.in (same date)
included in the openldap_2.4.23.orig.tar.gz file.
