"Certificate verify failed" when connecting via LDAPS

[Matthew X. E. <xen...@ir...>]

All,

I'm using Python-LDAP together with some additional plugins to
facilitate Plone authentication against Active Directory.  When I try
to configure the Plone software to use LDAPS, I get an error similar
to the following:

2007-08-14T15:17:20 CRITICAL event.LDAPDelegate Failure connecting,
last attempted server: ldaps://svr1.irtnog.org:636 ({'info':
'error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate
verify failed', 'desc': "Can't contact LDAP server"})

(I've elided the traceback provided by Zope.  This error is generated
by the Python-LDAP module.)

I'd like to find out how to disable the verification check or to add
my enterprise root CA certificate to Python-LDAP's notion of trusted
root certificate authorities.  Would someone point me to the relevant
documentation or code?

Thanks in advance,
Matthew
