20 GRUF3 Feature-preview stuff.
21
22 This code shouldn't be here but allow people to preview advanced GRUF3
23 features (eg. flexible LDAP searching in 'sharing' tab, ...) in Plone 2,
24 without having to upgrade to Plone 2.1.
25
26 Methods here are monkey-patched by now but will be provided directly by
27 Plone 2.1.
28 Please forgive this 'uglyness' but some users really want to have full
29 LDAP support without switching to the latest Plone version ! ;)
30
31
32 BY DEFAULT, this thing IS enabled with Plone 2.0.x
