Okay, so here is the deal (at least in my situation). I should have stopped after I issued the third command:
1. zmprov mc default zimbraFeatureNotebookEnabled TRUE
2. zmprov mcf zimbraNotebookAccount
wikiONE@primary.com
3. zmprov in
wikiONE@primary.com password /opt/zimbra/wiki/Template Template
It looks like irrespective of whether or not I have virtual domains installed, I only need to install the templates to
wikiONE@primary.com. Once I have this working, the wiki automatically appears for
admin@secondary.com and all of the other accounts I mentioned in the original post. Sorry to take up the bandwidth!
