I'm just wondering about the dovecot part, whether dovecot will do Unexpected Things if more than one user have the same home and mail_location? If it makes any difference, the users can have separate homes, but the mailbox should be the same for usability.

Thanks, overriding the userid seems to be working fine.

After getting this to work I realized otp tokens aren't the best for use 
at the imap layer. The first authentication goes through fine. But on 
the next imap connections (parallelizing clients and typical webmails) 
the cached password/otp token has been used already and is rightfully 
rejected by the backend authentication system.

By turning on auth caching in dovecot I jury-rigged this to work (for 
the duration of the auth cache), but the clean solution would be 
something else. Anyway I think I'll settle here for now, better than a 
static password anyway. Thanks for the comments and keep up the good 
work with Dovecot!
