There's one sure fire way to find out...
Start it up with a syncrepl, then move the private key, and see if it syncs fine both ways.
Wait a day or so, and make a change and see if that synced.
If I had to put a dollar on it, if guess that it doesn't need the key after
startup. I could be horribly wrong though - I'm not a dev, just a user of the software.
It probably depends on which crypto library you built with. I'm pretty sure OpenSSL and GnuTLS cache the PEM credentials in memory. Not sure what MozNSS does. And of course, if you're paranoid, you can build these libraries to use smart tokens and leave the credentials there instead.

Alex, encrypting the private key really isn't necessary and I highly doubt it would work for your application nor be worth the hassel. Securing via file permisssions as mentioned previously is really the best way to tackle this. Think of 'other layers of protection' being firewalls, intrusion detection, restricted logins, chroot jails, etc., etc...
yep go those, firewalls, permissions etc.
I am not sure why every one is against me trying to use another layer of protection, just because I permission it as root.root 440, doesn't mean its safe. I could make it safer, but unecrypting the private key, starting slapd and removing the unecrypted file.
Or thing of it another way, my private key could be on a usb key, that i insert into the machine on start up and remove once slapd has started.
I have seen secure machine compromised before, somebody installed cvs forgot to change the cvs userid password, root hack and a remote user had access to the system. Some times people do silly things
on my laptop - I encrypt the fs and the swap space and my gpg key have userid/passwords and my certs have userid password protection, like to do the same for my ldap setup as well :)
I understand the reasons for encrypting and signing packets or information, just asking if slapd needs access to the private key after it has read the file on startup.
Encryption really works best for UDP like transportation like email where you cannot guarantee the recipient is the only person able to 'see' the document ;)
