OK, thanks for the info. I don't know much acout the internals of
OpenLDAP, but I can still see where non-malloc()ed memory is being passed

We use a custom plugin to keep Kerberos ACLs in sync with group
memberships. The plugin only monitors for certain changes to the
directory, it does not modify the directory in any way.
