This codebase is no longer under seriously active development. It has has been folded into http://www.dataflake.org/software/ldapuserfolder/
which is maintained by Jens Vagelpohl. You are advised to look there if thinking about using LDAP with Zope
The new Zope 2.2.0 has modifications in the API, that makes all previous versions of LDAPAdapter break. I have just released a new version of LDAPAdapter, which supports Zope 2.2.0, but since documentation on the new interfaces in Zope is sketchy, I have been forced to guess quite a lot. Be warned. There mighht be bugs.
We have imported the sources into CVS. The initial version matches what you know as version 0.98.2. In the time that passed Ross has modified the source and that is patched into the version 0.98.2.
You can get the 0.98.2 source with tag v_0_98_2 and the version 0.98.4 with tag v_0_98_4.
I'd like to move the zope LDAPAdapter product here so we can make the development process more publicly available.
This is, after all a security add-on for zope which some people are going to depend on - the opensource saying that many eyes make bugs shallow" applies particularly to security code.
So, if you use this package, please do whatever you can to make it better. Contributions to the codebase or the documentation will be warmly welcomed.
