[Bug 1866303] Re: slapd crash with pwdAccountLockedTime and stacked overlays
We're no longer looking at backporting fixes for disco.
This looks suitable for SRU so the other proposed series tasks are
valid, and this is already in the server-next queue.
** Changed in: openldap (Ubuntu Disco)

Bug 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
