I've been trying, unsuccessfully, to set up ppolicy in my installation (2.4.21 on Ubuntu). As soon as I set up the overlay (before I even configure a user with a password policy or set up a default policy), slapcatting the database results in a segmentation fault. I tried it on 2.4.23 and 2.4.17 with the same results. Here is the configuration I'm using, and a backtrace from the 2.4.21 installation:

As soon as I remove olcOverlay={3}ppolicy from the backend database, the problem disappears. The configuration isn't anything special so I don't think it's a misconfiguration issue, but I figured I'd get a second opinion from the list before submitting this issue as a bug to the ITS. As always, all advice and input is appreciated.
