Hello, We're trying to convert a large site over to Zope which makes some heavy use of information stored in an RDBMS and wondered if anyone has done any work extending the BasicUserFolder/BasicUser classes so that they get their information from an RDBMS instead of Bobo? How about any pointers to code which can be used as a starting point?

How about a complete product? http://www.zope.org/Download/Prereleases/UserDB

Another question we had was if it would be possible to extend acquisition to include properties/methods defined for the currently authenticated user?

What do you mean by extend? It is possible to edit the user folder code, or to create a ZClass which subclasses it to modify the type of object returned by validate(). IMAPAdapter does this, it's validate() method actually works with a low level connection manager to return a User object which defines a whole IMAP API and a connection logic (including connection caching and automatic connection reconstruction). Thus, IMAP operations happen from the perspective of AUTHENTICATED_USER, like so: <dtml-var standard_html_header> <dtml-with AUTHENTICATED_USER> <dtml-tree expr="imapFolderTree(REQUEST)" sort=id nowrap=1> <img src=<!--#var icon>> <dtml-var shortname> <dtml-if num> (<dtml-var num>) </dtml-if> </dtml-tree> </dtml-with> <dtml-var standard_html_footer> imapFolderTree() is a method of the User object. http://www.zope.org/Download/Contrib/IMAPAdapter-0.1.0-nonbin.tgz -Michel

This would be useful for user preferences, etc...

thanks, -jeff
