Re: LDAP Polling

[Yeargan Y. <ya...@un...>]

Hmm. That only moved the exception.

   File "/usr/lib/python2.4/site-packages/ldap/ldapobject.py", line =20
421, in result3
     rtype, rdata, rmsgid, serverctrls =3D ldap_result
ValueError: need more than 3 values to unpack

I put the statement above into a try..except block and checked the =20
value when the exception occurs. This line

ldap_result =3D self._ldap_call(self._l.result3,msgid,all,timeout)

assigns (None,None,None) to ldap_result, a 3-tuple instead of a 4-tuple.

Once data becomes available from the LDAP server, then it returns a 4-=20=

tuple as expected.
