Hi, I'm trying to use LDAPUserFolder with Zope 2.6.1 and python2.1.3 under RedHat 9.0. (By the way, RedHat 9.0 installed python2.2 too) I installed python-ldap-2.0.Opre13.tar.gz. The result go through /usr/lib/python2.2/site-packages/ld* files and sub directory ldap... I copied /usr/lib/python2.2/site-packages/ld* files and subdirectory ldap to /zope/lib/python2.1/site-packages. (Is it really necessary?) Now if I go to /zope/bin/python and type import _ldap I've got an error message which is: importError /usr/lib/python2.2/site-packages/_ldap.so: undefined symbol:ldap_first_reference I believed /zope/bin/python use /zope/lib/python2.1 but its seems wrong!!! Now I think I have to install an openldap package to resolve ldap_first_reference but I don't know it's name for redhat 9.0... Is there anybody to help me? Thanks. Patrick Gelin
