Hello all,
I'm currently attempting to use rlm_python to query LDAP (with python-ldap) and
then return an XML string in a VSA (SAML-AAA-Assertion). However, when I try to
load it, I get the dreaded "undefined symbol: PyExc_SystemError" error. This is
on Ubuntu 12 with, I know, I know, FreeRADIUS 2.1.10. Python-LDAP was built on
the local machine for the newest version (although the existing version in the
Ubuntu repository has the same problem).
Freeradius_samlldap exists in the correct path for Python eggs, and this is the
PYTHONPATH (when I print it with Python):
/usr/local/lib/python2.7/dist-packages/pysaml2-0.4.2-py2.7.egg,/usr/local/lib/python2.7/dist-packages/repoze.who-1.0.18-py2.7.egg,/usr/local/lib/python2.7/dist-packages/zope.interface-4.0.5-py2.7-linux-x86_64.egg,/usr/local/lib/python2.7/dist-packages/Paste-1.7.5.1-py2.7.egg,/usr/local/lib/python2.7/dist-packages/httplib2-0.8-py2.7.egg,/usr/local/lib/python2.7/dist-packages/decorator-3.4.0-py2.7.egg,/usr/local/lib/python2.7/dist-packages/freeradius_samlldap-0.0.1-py2.7.egg,/usr/local/lib/python2.7/dist-packages/python_ldap-2.4.13-py2.7-linux-x86_64.egg,/etc/freeradius/modules,/usr/local/lib/python2.7/dist-packages,/usr/lib/python2.7,/usr/lib/python2.7/plat-linux2,/usr/lib/python2.7/lib-tk,/usr/lib/python2.7/lib-old,/usr/lib/python2.7/lib-dynload,/usr/lib/python2.7/dist-packages,/usr/lib/pymodules/python2.7

The usual debug log is below:
