[Other Info] This was fixed in focal and "cooked" there for a long while, as suggested by the Debian maintainer. We haven't received further bug reports about this in focal+. [Original Description] Hello, Please merge openldap 2.4.49+dfsg-2 from Debian unstable to fix an issue in the ppolicy overlay that can crash slapd. Please also consider SRUing the patch after it has had some testing time. Upstream: https://openldap.org/its/?findid=9171 Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=953150 The ingredients for the crash are: 1: ppolicy overlay configured with pwdLockout: TRUE 2. smbk5pwd overlay stacked after ppolicy 3. an account locked out via pwdAccountLockedTime 4. a client binding to the locked-out account and also requesting the ppolicy control The buggy code is not as specific as the above steps, so I suspect there are probably other configurations or steps that can trigger the same crash. I will attach my test script and data for reproducing the crash. Expected output (last lines): [ ok ] Starting OpenLDAP: slapd. slapd running ldap_bind: Invalid credentials (49) slapd running Actual output (last lines): [ ok ] Starting OpenLDAP: slapd. slapd running ldap_bind: Invalid credentials (49) slapd dead To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openldap/+bug/1866303/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : firstname.lastname@example.org Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
