In major linux distributions, the slapd is copmiled as shared object. There are projects (nordugrid.org arc) for example) using slapd object to build custom grid related services. Is it possible to add the pie patch to openldap ebuild (taken from fedora), verified to work well on 2.4.17-r1?

Reping
Well, I have forgotten about that. Seems some additional patches are needed to compile some of the code with fPIC. As a workaround I have created an additional ebuild to compile slapd only. Will take a look again at fedora spec file.
This pretty much timed out, right?
Well, it turned out it is much easier to build a custom slapd executable in a separate ebuild.
