Long story short: Is it appropriate to change self.REQUEST.AUTHENTICATED_USER.name to self.REQUEST.REMOTE_USER ? It appears to work but I'm not sure if there may be repercussions on this. Thomas Long story: I had to make the change in getUserVariable(self, key, default=None) to view events CorpCalender 1.4 that was exported from Zope 2.6.1 and make the change in rememberUserVariable(self, key, value) to be able to add events in CorpCalendar 1.7 newly created calendars in Zope 2.9.6. I can't manage/edit any events in the imported CorpCalendar but I'm not real concerned about that because we can add the new calendars to carry on from the last dates on the old ones.
