Thank you for your submission. I must compliment you on providing such a
comprehensive and well-written contribution. Unfortunately the feature itself
is clearly not useful. Perhaps you should have raised this topic on the
openldap-devel list for discussion before spending your time writing it.
All your feature does is embed the encryption key in the filesystem, so an
encrypted private key is still no more secure than an unencrypted one. It
still just depends on setting proper file access permissions, and the current
documentation already makes that point.
Indeed, all it does is give the false illusion of enhancing security, and
followups like email@example.com's shows that people will easily fall for
I regret having to reject such a well written contribution, but we cannot in
good conscience accept a security feature that doesn't actually improve security.
