[Zope] ZopeLDAP with Zope 2.2 - verify_watermark ImportError

I just installed ZopeLDAP in Zope 2.2 and I am getting the following message: Traceback (innermost last): File "/usr/local/Zope-2.2.0-src/lib/python/OFS/Application.py", line 396, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/usr/local/Zope-2.2.0-src/lib/python/Products/ZLDAPMethods/__init__.py", line 24, in ? import LM File "/usr/local/Zope-2.2.0-src/lib/python/Products/ZLDAPMethods/LM.py", line 42, in ? from AccessControl.User import verify_watermark ImportError: cannot import name verify_watermark Is there a patch available? If not, does anyone know a work around? Thanks.
