[Zope] Zope/Apache and Microsoft Active Directory

[Pieter Biemond prive]

Hello,

Did anybody ever get Zope and/or Apache to authenticate against a
Micrsoft Active Directory? I tried using LDAPUserfolder on Zope
2.5.1/Python 2.1.3 but I'm getting all sorts of errors, e.g.

Logging:
ldapuser not found (getUser)

User-info:
(###Error###: ldap.OPERATIONS_ERROR, {'desc': 'Operations error',
'info': '000020D6: SvcErr: DSID-03100690, problem 5012 (DIR_ERROR), data
0\n'})

Did anybody else have more luck, 
or any idea where to start debugging?

Pieter
