No.

Maybe. It really depends...

Note that the caching in OpenLDAP client libs was considered broken.
That's why the wrapper code for making OpenLDAP's client-side caching
available to python-ldap was removed.

I'd go for sub-classing LDAPObject and hook into method search_ext_s().
Well, caching for async search operations does not really make sense
anyway.

Issues which come to mind:
* There can be lots of subtle details to consider which might lead to
different search results (e.g. access control, the ManageDSAIT controls,
etc.)
* take care of flushing the right objects from your cache when modifying
entries
* for security reasons flush your whole cache when (re-)binding on a
given LDAP connection

I'm sure there are more issues...
