Hmm, I have no clue why that happens. I've never had this problem 
except with some very strange LDAP servers like bigfoot's.

Howard, how to make sure the LDAP request is flushed?

Allan, if this problem occurs again can you post the relevant 
snippets of your Python code and can you also use trace_level=1 
when calling ldap.open() or ldap.initialize() which writes a trace 
log containing all the python-ldap API calls (maybe solely on 
python-ldap-dev).

Ciao, Michael.
