slapd crash with pwdAccountLockedTime and stacked overlays

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
