I am trying to use the asynchronous LDAP polling feature and have a
question about what appears to be a timing issue. When I run the code
below, I find that I must insert a sleep() before entering the while
loop or I get a ValueError exception.

File "/usr/lib/python2.4/site-packages/ldap/ldapobject.py", line 415,
in result3
rtype, rdata, rmsgid, serverctrls =
self._ldap_call(self._l.result3,msgid,all,timeout)
ValueError: need more than 3 values to unpack
Hmm, this should never happen. I guess it's caused by _ldap.result3()
returning NULL for the situation where no result was received at all. I
will look into it.
In the meantime try if the patch to LDAPObject.py attached solves your
problem.
Ciao, Michael.
