Local Error in simple_bind_s();

[Leons Petrazickis]

Hi Michael,

Thank you very much for the logging tip.

I've installed Thorsten Kurbad's python_ldap-2.3.1-py2.4-linux-i686.egg on
my Python 2.4 install

This is the script:

ldap.set_option(ldap.OPT_DEBUG_LEVEL,4095)

l = ldap.initialize("ldap://bluepages.ibm.com:636/",trace_level=2);
l.protocol_version = ldap.VERSION2;
l.simple_bind_s();

And this is the log output:

Does this mean that the connection is successful, but then there is a crash
in message processing? What can I do?

I have no clue which version of python-ldap Ubuntu is using. Nor do I
know whether they applied any patches *they* believe to be necessary
before packaging it. Could you please try to reproduce the problem with
a stock python-ldap 2.3.1 built from official source distribution
against recent OpenLDAP libs 2.3.x?

Another option to track down issues is to turn on debug logging in
python-ldap and also in the OpenLDAP libs:

ldap.set_option(ldap.OPT_DEBUG_LEVEL,4095)

and

l = ldap.initialize('ldap://yourserver:port',trace_level=2)

Ciao, Michael.
