I have a vague memory of dealing with this issue (ldap/apache); I
think the problem was a mismatch of Berkeley DB libraries (sleepycat).
I had built openldap against the latest sleepycat distro, but apache
was built against my standard RedHat distro.  No faster way to core
dump apache!

Make sure apache/python-ldap/openldap are all in sync.  The ldd
utility can help you figure out which binary/library is dependent on
what.
