Hi, A while ago zope.pluggable split off reusable components from zope.app.authentication. The concrete IAuthenticatorPlugin implementations (principalfolder and groupfolder) however, were left in zope.app.authentication. I think it makes sense to move these IAuthenticatorPlugin implementations to zope.pluggableauth.plugins as well, leaving backwards compatibility imports and the browser code in zope.app.authentication. For both packages I created branches [1][2] for working on this. I moved the components and made sure the tests pass again. If there're no objections I'd like to merge these branches to the respective trunks and eventually release zope.pluggableauth 1.1.0 and zope.app.authentication 3.9.0. kind regards, jw [1] http://svn.zope.org/zope.pluggableauth/branches/jw-authenticator-plugins/ [2] http://svn.zope.org/zope.app.authentication/branches/jw-move-authenticator-p...
