> When I try to do a search using python-ldap:
> import ldap
> l = ldap.initialize('ldap://localhost:10389')
> l.simple_bind_s('uid=admin,ou=system', 'secret')
> l.search_s('', ldap.SCOPE_BASE, "", ('vendorName', 'vendorVersion'))
> NB: the empty string "" is normally "(objectClass=*)", but for this bug to happen, pass
an empty string, or even "()".
