RE: ldap.ENCODING_ERROR when trying to use SimplePageResultsControl

[<pyl...@ne...>]

Michael,

I've run into the same problem as Joel on basically an identical setup
- CentOS 5.2, openldap 2.3.27-8.el5_2.4, python 2.4.3-21.el5,
python-ldap 2.2.0-2.1. This of course being on a 64 bit release of
CentOS.

I did as you suggested and updated openldap to 2.4.12-1, and
python-ldap to 2.3.5-1, but I still received the exact same error.

Because you mentioned that you had never tested python-ldap on a 64
bit machine, I duplicated my setup in a VirtualBox VM only using a
i686 release of CentOS rather than x64.

I ran my python program using the old versions of software ( openldap
2.3.27-8.el5_2.4, python 2.4.3-21.el5, python-ldap 2.2.0-2) and it ran
without any problems whatsoever.

Any suggestions on how to fix this?

Let me know if you need any other info.

Dominic

These releases are old:
OpenLDAP 2.3.27 was released 2006-08-19
python-ldap 2.2.0 was released 2006-04-10

There have been numerous bug fixes to both packages since then. While I
don't have a 64-bit box myself there were several related fixes
contributed and tested by others. So I suggest to build recent releases
of both from source and test with that.

Whatever stable means to Red Hat for these particular packages. Sorry,
if you insist on using these ancient versions I have to point you to Red
Hat's support.

Ciao, Michael.
