How to enable logging in Python LDAP

When writing Python scripts which rely on python-ldap and openLDAP, it is often useful to turn on debug messages as follows:

import ldap;

# enable python-ldap logging
ldap.set_option(ldap.OPT_DEBUG_LEVEL, 4095)

# enable openLDAP logging
l = ldap.initialize('ldap://yourserver:port', trace_level=2)

This is also useful when debugging the LDAP Plugin for Trac.
