[Zope] Multiple user folders

Hi all, this is a question that arose in one client situation where part of the users were defined in LDAP and others were just defined in normal user folder. Client had created a drirectory structure where on the subfolder he had the LDAP userfolder and normal userfoder on top folder, this way authentication worked for both groups. However I started to think whether anyone had done yet a userfolder that could have multiple sources for users in one userfolder? -- -huima
