Plone 5 compatibility

[jkubaile]

Hi,

i am trying to use plone.app.ldap in a Plone 5 environment. Installation via buildout was fine. Quick Installing in Plone works also. But using the control panel view and adding a new server or a new schema leads in the following error:

I would suggest, that it has something todo with the formlib based forms, which are used here. It was possible to set servers and schemas via the debugger. Than the access to the users and authentication seems to work also...

Here's a minimal Plone 5.1 buildout that makes this all work.
We need the BBB import to exclude some CMFDefault bits, the p.a.form overrides, and we need to mark the views as ITraversable so we use (un)restrictedTraverse to get to the main_template.

[buildout]
parts = instance
extends =
    http://dist.plone.org/release/5.1rc2/versions.cfg
versions = versions

[instance]
recipe = plone.recipe.zope2instance
user = admin:admin
eggs =
    Plone
    plone.app.ldap
    plone.app.form
zcml =
	Products.CMFPlone:meta-bbb.zcml
	plone.app.form
zcml-additional =
	<include package="plone.app.form" file="overrides.zcml" />
	<class class="plone.app.ldap.browser.baseform.Adding">
      	  <implements interface="OFS.interfaces.ITraversable" />
        </class>

I gave this minimal buildout a shot with Plone 5.1.5 but am getting these errors. It looks like it's trying to grab plone.app.ldap 1.4.3.

Hi @tkimnguyen , I'm going through this same problem in Plone version 5.1.

Any palliative solution?

[tkimnguyen]

I haven't revisited this, and unfortunately I'm not recalling what I did to get around or over this (or if I just gave up).

[almeidajeff]

I ended up giving up too and ended up using pas.plugins.ldap
